My customer has software that is supposed to generate multicast traffic, but it may be faulty. Tcpdump prints out a description of the contents of packets on a network interface that match the boolean expression; the description is preceded by a time stamp, printed, by default, as hours, minutes, seconds, and fractions of a second since midnight. address LLADDRESS (default) the link layer multicast address. The VLAN ID used to get VXLAN vmknic multicast group info. Click Details. If necessary, convert the switch port to individual interfaces. x releases, the capture filter dialog box is no longer available in the capture options window. In MoveIt!, the simplest user interface is through the MoveGroup class. I made a Windows console application in C++. I need the multicast to only be available on this vlan. Partitioning instances. create ip igmp destination=224. I just need to make sure that the interfaces are active, have viable configurations, are multi-cast enabled, that the routing is applicable, that each machine is a member of the same multi-cast group, that there are no iptables rules preventing communication, and that no active device between them is preventing communication. which uses corosync and cman, and would apply to any other solution which utilizes those clustering tools. don’t forward if interface has been pruned 4. From this RedHat mailing list entry. IP_MULTICAST_IF: Sets the interface over which outgoing multicast datagrams are sent. Add a firewall multicast policy to forward the stream from the loopback interface to the physical outbound interface. 0/8) traffic). netstat command – It is used to display network connections, routing tables, interface statistics, masquerade connections, and multicast memberships. An interface index is a 24-bit number, and the 0. Add a Description. The Algo IP voice paging and notification system is a network-based fully scalable solution for any size room, building, campus or enterprise environment. An interface that is not operational is, for example, an ethernet port on a switch with no cable plugged in. Select the Interfaces from the drop-down menu and add it to the group. When I check the multicast group ip address which the two machine joins (command used: " netsh interface ip show joins" ), it shows different group of multicast group ip address. Multicast Configuration Comparison of Cisco IOS and Nexus OS Carol Kavalla, CCSI, CCNP, CCDP Introduction Multicast is supported in the Cisco IOS, IOS XR, IOS XE, and in the Nexus OS. You can manually add a multicast group to individual ports only. 3ad standard defines a means to bundle multiple Ethernet interfaces into an aggregate group. With this configuration, traffic can flow between both routers’ VLAN 26, but can’t escape since there is no L3 gateway. The IP Multicast Interface Settings window appears. A multicast MAC address is used in HP Network Adapter Teaming for the purpose of transmitting and receiving heartbeat frames (refer to “Heartbeats. Any pre-existing elements at or beyond the point of insertion are shifted up. Note: The group configuration window gives you an option to select the version of the OPC interface to use. Multicast packets are kind of a mixture between those two concepts. An IPv6 multicast address is an identifier for a group of interfaces (typically on different nodes). To create a multicast scope, follow these steps: Within the DHCP management console, right-click the DHCP server and choose the New Multicast Scope option. 1) is joined on the local 9. VideoLan media player (VLC) is an incredibly versatile media player available for Windows, Linux and other *Nix clones. Choose from: Show alarm for all "disconnected" states: The sensor for the interface will always turn into a Down status for a disconnected interface. ) This type of interface is usually a NIC connected to the network by a category 5 cable.

Blocked Causes the switch to drop all IGMP transmissions received from a specific port,. Click Account Setup, and then Shared Contacts. Various RP discovery mechanisms are used, including static configuration, Bootstrap Router, Auto-RP, Anycast RP, and Embedded RP. Applying Interface Group to a WLAN. Each membership is associated with a single interface. eligible to receive multicast data it must become part of the Multicast Group. wlan0 is the name of the first wireless network interface on the system. Further reading. If netstat -ng shows multicast groups being registered to, it means multicast support is available in kernel. Key concepts in IP multicast include an IP multicast group address, [2] a multicast distribution tree and receiver driven tree creation. I've been banging my head against the desk for a while now with this problem, but hopefully one of you can help me. 125 , then alias ip address must be 172. The multicast traffic is spread by multicast routers across the network from source to destinations. x releases, the capture filter dialog box is no longer available in the capture options window. If optval is zero , the default interface for receiving multicast is specified for sending multicast traffic. On the Cisco ® switch, add the FastEthernet0/1 and FastEthernet0/2 interfaces to channel group 1: interface FastEthernet0/1 channel-group 1 mode active channel-protocol lacp!. ConfigurePIM on S-Series interfaces routing multicast interface vlan. You can add up to 10 people to your Group at once. Here, if an interface is indeed an output interface for a particular multicast address, its TTL threshold is set to the real value; otherwise it is set to zero. On a node which is part of the cluster after setting up the environment variables like the Oracle Base, Grid home, Path and ASM SID, run the addnode. dev NAME the device to join/leave this multicast address. Step 3) In this step, Add a description for your network interface; Select the subnet where you want to create your network interface. dev NAME the device to join/leave this multicast address. The newer IGMP proxy feature and the older IGMP snooping feature cannot be enabled at the same time, as both features add membership information to multicast group table. 1 will be translated as unicast to 22. This means that IGMP traffic will be forwarded on a specific port only if an IGMP host or multicast router is connected to the port. IP_DROP_MEMBERSHIP: Leaves the multicast group specified. For me ping of multicast address works always, even if sender uses incorrect interface, but changing routing tables might help. This displays the statistics page for existing Multicast groups configured for a specific site in the SD-WAN GUI. The multicast group and port used by the repeater correspond to the default SPDP multicast group and port. To remove the host from the multicast host group you must issue a SETSOCKOPT call with the IP_DROP_MEMBERSHIP option. NOTE: In this chapter, the word "router" and the router icon used in figures refer to a conventional router or a Layer 3 switch. Set how members will get email from the. Also, as you’ve probably guessed, IPv6 isn’t enabled by default on any interfaces either, so we have to go to each interface individually and enable it. Example for a wired connection: ip maddr add ff02::fb dev eth0 Example for a wireless connection: ip maddr add 224. This allows multiple interfaces separated by comma. pppx(4) interfaces are members of the pppx interface group. Plays audio from multicast; SIP endpoint or multicast group member; Supports up to 10 multicast paging groups; Add an optional SL-2 blue, green, red or amber strobe light (see DOD 242) Blue call status LED indicator; Automatic Noise Canceling (ANC) feature for operation in noisy environments. Only those nodes that subscribe to a group receive packets communicated to the group. The multicast group is configured (or assigned) a specific multicast address. The guest cannot see multicast traffic by default if you use the VMXNET 3. IGMP is an asymmetric protocol and is specified here from the point of view of a host, rather than a multicast router. hi,bro: From output from 45001-E1-CORESW1#show ip igmp groups 232. set pim-mode sparse-mode. When troubleshooting a Multicast issue in KB21586 - Resolution Guide - Troubleshoot Multicast issue with Junos OS device configured as Layer 3 (running PIM protocol) you may need to check if the LHR has received the Multicast stream (traffic) from the source address S, for the Multicast Group G. In our example, the security policy allows multicast packets received by the internal interface to exit to the external interface. About the Author: JOHN MOY is a senior staff engineer at Proteon, Inc. To join a multicast group you must issue an IGMP join command. It should instead look like this: sudo route -nv add -net 228. Locate the contact that needs the new group member. dwIfNextHopIPAddr. IP Classes. 1 as a default gateway. If optval is zero , the default interface for receiving multicast is specified for sending multicast traffic. Use IP_ADD_MEMBERSHIP and IP_DROP_MEMBERSHIP to switch multicast groups "listened" for by the recieving socket. Only VLAN aware devices can accept them if. Introduction. If no interface is specified, then the multicast group is joined on INADDR_ANY, meaning that multicast transmissions received on any of the host's network interfaces will be forwarded to the socket. Click Next. txt-file and the third field remains empty. Adding a line such as this to the /etc/firewall. Multicasts are used a lot between routers so they can discover each other on an IP network. If netstat -ng shows multicast groups being registered to, it means multicast support is available in kernel. Multicast Server (Source): The Multicast source sends the stream on a Multicast group address, for which the client has requested. (A "multicast group membership" indicates that a machine is listening to messages for a specific multicast IP address. For instance, if you would like to change the multicast flag on or off for your interface, you can type: ip link set eth1 multicast on ip link set eth1. 119/16 net0/v4 #ipadm create-addr -T static […]. Various RP discovery mechanisms are used, including static configuration, Bootstrap Router, Auto-RP, Anycast RP, and Embedded RP. IP Multicast Boundary In this post we'll take a look at the ip multicast boundary interface-level command. This will cause multicast UDP packets to have a TTL of 2 prior to being routed by OpenWrt allowing them to be sent out the LAN interface with TTL=1. Click Next. A multicast application need only increase the Internet Protocol (IP) time-to-live (TTL) value to more than 1 (the default value) to allow outgoing datagrams to traverse routers. Specify a range of IP addresses and a TTL (see Figure 3. It should instead look like this: sudo route -nv add -net 228. The TTL in the IP header will be reduced by 1. check incoming interface: discard if not on shortest path to source 2. The multicast configuration on the CE router will be the standard type of enterprise multicast configuration. The default installation uses the Proxmox VE Firewall, which is not activated by default. Restarted application and client and still the same issue. To leave a group, use.

Multicast group capacity: Extreme comes out on top and ISPs with IPTV offerings use multicast to add and remove subscribers. 255 is reserved to reach multicast groups on a local network. VXLAN and Multicast A VTI is treated as an L2 interface in the VLAN for handling multicast traffic, which is mapped from the VLAN to the multicast group associated with the VTI. This is the main interface that Windows 8 user's use to launch applications. UTC In some situations it is desirable to manually configure multicast group membership on a router interface, particularly during testing and in the absence of IGMP-capable recipients. I want to join multicast group. The simplest way would be appreciated. Describe the types of IP multicast addresses. Add a Description.

The value range for this field is 5 to 60 (minutes). Add the physical interfaces to the bridge group. In the box under “Name” enter the new group contact member name. For each interface, choose how the interface is associated with the IP multicast. These query messages occur after a IGMP leave message is received by the router. Finally we will look at how we can map these interfaces or interface group to a WLAN. Current research interests include routing and multicast in datagram internetworks. Microchip's USB solutions are designed to support the growing needs of these markets with a full complement of robust, highly integrated USB PIC ® MCUs and dsPIC ® DSCs and USB Hubs and devices. Sparse mode In order to identify whether router that acts as default gateway should or should not send multicast traffic out of any interfaces, IGMP is used. About the Author: JOHN MOY is a senior staff engineer at Proteon, Inc. If no interface is specified, then the multicast group is joined on INADDR_ANY, meaning that multicast transmissions received on any of the host's network interfaces will be forwarded to the socket. Last week we reviewed all the tips & tricks to troubleshoot Open vSwitch and OpenStack Neutron. Paging Multicast - is suitable for large paging groups and requires phones supporting multicast, on the same local subnet as 3CX. To authenticate themselves, users must have access to an authentication client. 13) so that PIM routers may discover neighbors on a multi-access network. UTC In some situations it is desirable to manually configure multicast group membership on a router interface, particularly during testing and in the absence of IGMP-capable recipients. config interface. Multicast group list: Specify multicast group IP address or network address separated by a comma that will be served by given RP. route add -net 224. ConfigurePIM on S-Series interfaces routing multicast interface vlan. Static IGMP and MLD group memberships can be configured so that multicast forwarding can be set up without any host receivers in the group. Multicast tasks will send to all the computers in the group at once, and the task will not start sending until all members of the group have connected with the server. Two primary use cases supported in SD-WAN are:. But there is currently nothing about this supposed link between the –add-interface option and the NetworkManager component in the firewall-cmd man page. ping_group_range sysctl includes the above group ID. Sources use the group address as the IP destination address in their data packets. But I really don't know how to add a group to a interface, like adding a IP address 239. Hey, Where are my clusters? • All clustering services start on demand and stop when no longer demanded –Lifecycle example •Deploy app1, starts channel and cache. On the left, click Members Direct add members. Let's find the Multicast MAC address of this address and the other Multicast IP Addresses which has the same MAC address. Each membership is associated with a single interface, and it is possible to join the same group on more than one interface. Load Balancing IIS Sites with NLB. Choose your country or region. NSX vSphere (NSX-v) is a different beast, mostly because it leverage VMware Distributed Switch (VDS) instead of Open vSwitch. Invoke this rib-group inside protocols global mode. This is just the case of VMware environment, it may vary depends on the hardware but the steps to get back ethX will be the same. After reading it several times, which shouldn’t normally be necessary, I understand a specific role of the –add-interface option. DR priority is same for both Edge-1 and Edge-2 routers and hence highest IP address wins. The Multicast Routing section will now be available.

If nothing will work, try to add 224. The concept of creating or configuring multiple IP addresses on a single network interface is called IP aliasing. Choose from: Show alarm for all "disconnected" states: The sensor for the interface will always turn into a Down status for a disconnected interface. However, it doesn't receive Multicast packets that reach the vSwitch on VLAN 60. A full list of Exchange 2013 roles. You must increase this if you want to route the traffic, otherwise the first router will drop the packets! The default value is 1. Specifies the interface on which to add the group membership. The element exists at the target and up the map, labeled with processor group LOPGB. The concept of creating or configuring multiple IP addresses on a single network interface is called IP aliasing. Identify a group by its distinguished name (DN), GUID, security identifier (SID) or Security Accounts Manager (SAM) account name. The OSPF multicast group is a link-local multicast that gets sent to every switch interface, even with IGMP snooping enabled on the switch. The IP Multicast Interface Settings window appears. Commit the changes. Notice also that the MAC address of the source in the packet in Example 2-11 is the MAC address of the switch as depicted in the show interface Gi0/12 output in Example 2-12. This document is intended to be modified by FOG users, in fact it is based on a document created by a FOG user. 0/8 IPv4 address block is not used (this range is reserved). OnSSI is creating a new era in video surveillance in which intuitive software seamlessly connects and improves security processes and makes up for the limits of human capacity. The option value is the 8-byte packed representation of the multicast group address followed by the network interface on which the server should listen for the traffic, identified by its. Setup (Updated) In wireless, basic settings: enable "optimize multicast traffic" for all wireless radios, save and apply. Nowadays, the interests of the NFV layout focus on one-to-one communication, which is costly when applied to multicast or group services directly. To change an interface: interface / [speed <10_100_1000>|duplex |autoneg |flood rate ] To switch from autonegociation to 100FD, set autoneg off; speed 100 and duplex full; If forced in 100FD while autoneg is on, the port will stay down To disable an interface: interface / admin down. channel-group 47 mode. If my interface group have 10 dynamic interfaces, I should see 10 different MGID for the same multicast group address. If this DR fails, the other peer, who was originally non-DR but becomes the new DR, may need to establish SPT trees to get the multicast traffic or at the very least, add interfaces to OIF. As recommended by you, I have added vlan 3 interface to join this group. PACKET_MR_PROMISC enables receiving all packets on a shared medium (often known as "promiscuous mode"), PACKET_MR_MULTICAST binds the socket to the physical layer multicast group specified in mr_address and mr_alen, and PACKET_MR_ALLMULTI sets the socket up to receive all multicast packets arriving at the interface. - Host keeps a table of all groups which have a reference count > 0 Host sends IGMP leave to 224. VideoLan media player (VLC) is an incredibly versatile media player available for Windows, Linux and other *Nix clones.

IP aliasing is very useful for setting up multiple virtual sites on Apache using one single network interface with different IP addresses on a single subnet network. clients that belong to the same multicast group. If only the multicast interface is enabled, I am able to play the streams, with VLC, for example. Typical Network Designs With either the static or dynamic methods, multicast traffic only reaches those nodes subscribed to a multicast group - workstations A, B, and C. If this DR fails, the other peer, who was originally non-DR but becomes the new DR, may need to establish SPT trees to get the multicast traffic or at the very least, add interfaces to OIF. In the Filter: Interface Type equals to drop-down list, Step 3. HTTP : Stream by using the HTTP protocol. The Talk-Back Speaker system easily connects with a single CAT5/6 cable from your PoE switch. Setting the interval in seconds between successive state-refresh messages originated by the routing switch35. com - online owner manuals library. To test a configuration make an interface join a group and try to ping that group from another router. The IP address used in the example was 203. As the Routers will receive the request from host to join particular multicast group, They will check the multicast routing table which is received from PIM and in case of the router is not aware, The request will be forwarded to RP (Rendezvous Point). that interface must also be configured for PIM. Multicasting is based on a group membership concept, where a multicast address represents each group. [[email protected] grid]$. A basic VC domain includes a single HP c -Class BladeSystem c7000 Enclosure for a total of 16 servers (or up to 32 servers if the double -dense option is enabled), or a single HP c -Class BladeSystem c3000 Enclosure.

Specifies the interface on which to add the group membership. The multicast space reserved by IANA is 224. NET 1 le0 224. When Spine1 receives this packet it forwards it to all other Leafs who has joined the same multicast-group, in this case Leaf3. When it gets one, it will record senders MAC address, join requested group on upstream interface a listen for incoming multicast packets. In the Filter: Interface Type equals to drop-down list, Step 3. The multicast group is configured (or assigned) a specific multicast address. The show ip pim interface command shows the interfaces enabled for PIM on the router. 1 is the all-systems multicast address: all datagram sockets appear to be automatically member of this group on all interfaces. Solicited-node multicast address is generated from the last 24-bits of an IPv6 unicast (or anycast) address of an interface. As you can see in the following command, my system is having a network adapter called ens33. Proxmox VE host needs firewall protection. in the linked example The Linux socket and network programming on multicasting client-server with C program example both sender/receiver assign to a local ip 203. 0101 which corresponds with multicast group 239. With multicast routing enabled on the router, a PC connected to the other interface will send an IGMP Join message, and the Linux Router will begin sending the multicast traffic for the requested group to the interface. This guide provides the steps needed to add the GNOME Desktop to a CentOS minimal installation where the OS was installed without the X Window System. Specify an interface index for one of the host's interfaces to choose that multicast-capable interface. To receive multicast content, extra steps must be taken to join the multicast group that you want to receive packets from. Let's find the Multicast MAC address of this address and the other Multicast IP Addresses which has the same MAC address. Dense mode Multicast. In the Open Media dialog file tab, click “add” and choose the file you want to stream and click “Open”. Sources use the group address as the IP destination address in their data packets. The next code implements a server sending to the multicast group 224. ) This is where I get a little confused on how this address comes into play. set pim-mode sparse-mode. You can configure a separate. MLDv2 allows the socket to filter the incoming multicast data based on who sent it. So we could easily add every IP address from an entire subnet using this command: FOR /L %A IN (0,1,255) DO netsh interface ipv4 add address “Local Area Connection” 192. The multicast data for the group specified by the destination parameter will be forwarded over the ports specified by the port parameter. In IPv4, any address between 224. Those are sent from a host to a so-called “multicast group”, which hosts can subscribe to. If instead of the VLAN 60 port group I connect a port group with VLAN ID All (4095) to the same virtual machine, and a VLAN 60 interface on that machine using vconfig, I can see the multicast packets. Ethernet addressing scheme used to send packets to devices of a certain type or for broadcasting to all nodes. Multicast data for the specified groups will be forwarded out over this interface. config interface. Select this checkbox to improve performance by regulating multicast data to be forwarded to only interfaces joined into a multicast group address using IGMP. Boot Images and Distribution Point Configuration For OSD In SCCM 2012 R2 In this post we will look at the steps for boot images and Distribution Point configuration for OSD In SCCM 2012 R2. As the Routers will receive the request from host to join particular multicast group, They will check the multicast routing table which is received from PIM and in case of the router is not aware, The request will be forwarded to RP (Rendezvous Point). Also add static joins to the loopback interface for any groups to be translated. Note that this may not be the same address you bound to manually if you specified 0. 0 dev eth0 This is an obscure one documented so people know how to do it. SDVC assumes that all members of the group can send and receive packets over the multicast address. By default, the router uses IGMP version 2, which maximizes functionality, because version 3 has some restrictions. Select the Interfaces from the drop-down menu and add it to the group. 1 everything going through its standard input. Go to Interfaces and click Add. It can be a little bewildering to figure out how each of the options work, so I thought I'd write up what I found. Address assignments are listed below. Paging - add the extensions to page in the section “ Group members ”. Any Source Multicast (ASM), in which a receiver joins a multicast group, and receives traffic from any senders that send to that group. This command only manages link layer addresses. How can I generate multicast traffic? My customer has software that is supposed to generate multicast traffic, but it may be faulty. Multicast-based. In the CAM table above you can see an entry for MAC address 0100. The multicast clients need a mechanism to join multicast groups. 255) are assigned to multicast. PIM is a broadcast and pruning multicast protocol that delivers IP multicast datagrams. The following output shows the status of the Pseudowire. R6 now has to figure out how to get to the RP and request it to start forwarding the multicast traffic. 61 synonyms for broadcast: transmission, show, programme, telecast, webcast, transmit, show, send. Multicast scoping determines how far a multicast stream can travel from its source. It can also be used as a standalone recipe. Multicast address config lost On Solaris OS, We use the following command to config the multicast address for NIC in order to process the multicast packets: # route add 228. Describe how receivers can learn about a scheduled multicast session. They will all receive the datagrams sent to that group via that interface. Under multicast support, select Enable multicast routing. It has happened for the second time now that my server was not reachable anymore. View online or download Yealink SIP-T46S User Manual, Manual. multicast-iface “multicast-iface” gchararray The network interface on which to join the multicast group. IGMP allows the ports to detect IGMP queries and report packets and manage IP multicast traffic through the switch. Enter the rendezvous point (RP) and multicast group information. The notion of group is essential to the concept of multicasting. What happens here is the interface acts as a host which is listening to a multicast group and the router that is pinging that group address is acting as the multicast source. Static IGMP and MLD group memberships can be configured so that multicast forwarding can be set up without any host receivers in the group. multicast group, the switch will forward the leave message to the Layer 3 device (the querier). ip igmp join-group 239. • Group firmware update—Update the firmware of a group of servers. Z - Multicast Tunnel, z - MDT-data group sender, Y - Joined MDT-data group, y - Sending to MDT-data group Outgoing interface flags: H - Hardware switched, A - Assert winner. The operating system needs more information. 255 can be used as a multicast address. A group of hosts consists of both senders and receivers.

NIC Channel Bonding in RHEL 5 & 6 (CentOS & Oracle Linux) NIC channel bonding allows multiple network cards to act as one, allowing increased bandwidth and redundancy. SMCRoute supports dynamic multicast routing with the multicast group 'join' -j and 'leave' -l commands. These interfaces are also accessible from Onboard Administrator. 5 the all OSPF routers , 224. As said before, any multicast-capable hosts join the all-hosts group at start-up , so "pinging" 224. Generally Multicast Sockets should be bound to the wildcard address [INADDR_ANY], before joining the group. VLANs and IP Routing on an Ethernet Routing Switch January 26, 2011 by Michael McNamara 80 Comments I’ve had a number of discussions recently with people asking how to configure VLANs and IP routing on the stackable Avaya Ethernet Routing Switches. To do this in Dart, you can use the RawDatagramSocket. Enter the email addresses of the people to add. Compared to broadcasting and multicasting, manycasting uses the normal server keyword, but with a multicast group address (class D) on the client. I made a Windows console application in C++. Link Aggregation. joinMulticast(InternetAddress group, {NetworkInterface interface}) method. Description In a Mlag setup with Pim SSM, one peer becomes the DR for a layer 3 interface and is responsible for routing multicast traffic on that interface. This displays the statistics page for existing Multicast groups configured for a specific site in the SD-WAN GUI. This guide also applies to adding an administrator to Office 365 Exchange. The fact-checkers, whose work is more and more important for those who prefer facts over lies, police the line between fact and falsehood on a day-to-day basis, and do a great job. Today, my small contribution is to pass along a very good overview that reflects on one of Trump’s favorite overarching falsehoods. Namely: Trump describes an America in which everything was going down the tubes under  Obama, which is why we needed Trump to make America great again. And he claims that this project has come to fruition, with America setting records for prosperity under his leadership and guidance. “Obama bad; Trump good” is pretty much his analysis in all areas and measurement of U.S. activity, especially economically. Even if this were true, it would reflect poorly on Trump’s character, but it has the added problem of being false, a big lie made up of many small ones. Personally, I don’t assume that all economic measurements directly reflect the leadership of whoever occupies the Oval Office, nor am I smart enough to figure out what causes what in the economy. But the idea that presidents get the credit or the blame for the economy during their tenure is a political fact of life. Trump, in his adorable, immodest mendacity, not only claims credit for everything good that happens in the economy, but tells people, literally and specifically, that they have to vote for him even if they hate him, because without his guidance, their 401(k) accounts “will go down the tubes.” That would be offensive even if it were true, but it is utterly false. The stock market has been on a 10-year run of steady gains that began in 2009, the year Barack Obama was inaugurated. But why would anyone care about that? It’s only an unarguable, stubborn fact. Still, speaking of facts, there are so many measurements and indicators of how the economy is doing, that those not committed to an honest investigation can find evidence for whatever they want to believe. Trump and his most committed followers want to believe that everything was terrible under Barack Obama and great under Trump. That’s baloney. Anyone who believes that believes something false. And a series of charts and graphs published Monday in the Washington Post and explained by Economics Correspondent Heather Long provides the data that tells the tale. The details are complicated. Click through to the link above and you’ll learn much. But the overview is pretty simply this: The U.S. economy had a major meltdown in the last year of the George W. Bush presidency. Again, I’m not smart enough to know how much of this was Bush’s “fault.” But he had been in office for six years when the trouble started. So, if it’s ever reasonable to hold a president accountable for the performance of the economy, the timeline is bad for Bush. GDP growth went negative. Job growth fell sharply and then went negative. Median household income shrank. The Dow Jones Industrial Average dropped by more than 5,000 points! U.S. manufacturing output plunged, as did average home values, as did average hourly wages, as did measures of consumer confidence and most other indicators of economic health. (Backup for that is contained in the Post piece I linked to above.) Barack Obama inherited that mess of falling numbers, which continued during his first year in office, 2009, as he put in place policies designed to turn it around. By 2010, Obama’s second year, pretty much all of the negative numbers had turned positive. By the time Obama was up for reelection in 2012, all of them were headed in the right direction, which is certainly among the reasons voters gave him a second term by a solid (not landslide) margin. Basically, all of those good numbers continued throughout the second Obama term. The U.S. GDP, probably the single best measure of how the economy is doing, grew by 2.9 percent in 2015, which was Obama’s seventh year in office and was the best GDP growth number since before the crash of the late Bush years. GDP growth slowed to 1.6 percent in 2016, which may have been among the indicators that supported Trump’s campaign-year argument that everything was going to hell and only he could fix it. During the first year of Trump, GDP growth grew to 2.4 percent, which is decent but not great and anyway, a reasonable person would acknowledge that — to the degree that economic performance is to the credit or blame of the president — the performance in the first year of a new president is a mixture of the old and new policies. In Trump’s second year, 2018, the GDP grew 2.9 percent, equaling Obama’s best year, and so far in 2019, the growth rate has fallen to 2.1 percent, a mediocre number and a decline for which Trump presumably accepts no responsibility and blames either Nancy Pelosi, Ilhan Omar or, if he can swing it, Barack Obama. I suppose it’s natural for a president to want to take credit for everything good that happens on his (or someday her) watch, but not the blame for anything bad. Trump is more blatant about this than most. If we judge by his bad but remarkably steady approval ratings (today, according to the average maintained by 538.com, it’s 41.9 approval/ 53.7 disapproval) the pretty-good economy is not winning him new supporters, nor is his constant exaggeration of his accomplishments costing him many old ones). I already offered it above, but the full Washington Post workup of these numbers, and commentary/explanation by economics correspondent Heather Long, are here. On a related matter, if you care about what used to be called fiscal conservatism, which is the belief that federal debt and deficit matter, here’s a New York Times analysis, based on Congressional Budget Office data, suggesting that the annual budget deficit (that’s the amount the government borrows every year reflecting that amount by which federal spending exceeds revenues) which fell steadily during the Obama years, from a peak of $1.4 trillion at the beginning of the Obama administration, to $585 billion in 2016 (Obama’s last year in office), will be back up to $960 billion this fiscal year, and back over $1 trillion in 2020. (Here’s the New York Times piece detailing those numbers.) Trump is currently floating various tax cuts for the rich and the poor that will presumably worsen those projections, if passed. As the Times piece reported:
