Multicast Route Counters

Description This feature provides per multicast route ingress packet and byte counters for multicast routed packets. Platform Compatibility DCS-7020R DCS-7280R/R2/R3 (R3 starting EOS-4.23.1F) 7500R/R2/R3 (R3 starting EOS-4.23.1F) Configuration Per multicast route ingress packet and byte counters can be enabled/disabled using the following commands: Arista(config)#[ no ] hardware counter feature multicast ipv4   On DCS-7020R, DCS-7280R/R2 and 7500R/R2 platforms, create and apply user defined Tcam profile with multicast counter feature db enabled: Example: Create a profile copying from default and modify it: Arista(config)#hardware tcam Arista(config-hw-tcam)#profile <profileName> copy default Arista(config-hw-tcam-profileName)#feature counter multicast ipv4 Arista(config-hw-tcam-profileName-feature-counter-multicast-ipv4))#exit Arista(config-hw-tcam-profileName)#no feature mirror ip Arista(config-hw-tcam-profileName)#exit Arista(config-hw-tcam)#system profile <profileName>...

Global knob to set MTU for all layer 3 interfaces

Description Global layer 3 Maximum Transfer Unit (MTU) feature provides a CLI command to set the MTU value for all layer 3 interfaces. The default value for global layer 3 MTU and for each interface layer 3 MTU is 1500, which is unchanged from previous releases. Any interface which has an MTU configured will not be affected by the global L3 MTU. If the global L3 MTU is changed, any existing interfaces which are using the default will be updated to use the new MTU.  Any additional interfaces which are configured in the future will also use the new default...

Support for L3 MTU on 7280R3/7500R3/7800R3

Add support for Layer 3 MTU on 7280R3/7500R3/7800R3 switches. Description Enforces the MTU for Layer 3 packets on 7280R3/7500R3/7800R3 switches. The MTU can be set on any SVI and the MTU of that specific SVI is enforced when the packets egress out of a trunk port.  This behavior is not supported on 7280E/R/R2 and 7500E/R/R2 line cards. MTU enforcement is done after adding all of the encapsulation headers in the Egress packet. For example, if an interface is configured with an MTU value of 1500 and the packet size is larger than 1500 with all encapsulation headers added, the packet...

SNMP IP address ACL support

Description SNMP IP address ACL support provides the ability to add access-lists to limit the source addresses that can be used to query the SNMP server, reachable on the switch through the access SNMP data (port 161).  The access-lists will contain standard permit and deny commands. Platform Compatibility This feature is platform independent. Configuration [ no | default ] snmp-server ( ( ipv4 access-list IP4_ACL )  | ( ipv6 access-list IP6_ACL ) ) [ vrf VRF ] If VRF is not specified, “default” is assumed Show Commands show snmp ( ( ipv4 access-list [ IP4ACL ] ) | ( ipv6...

TAP Aggregation Extra MPLS Pop (4 to 6 Labels)

Description Extra MPLS pop is a feature for TAP Aggregation that allows one to remove 4 to 6 MPLS labels from a packet. Previously, only 1 to 3 labels were able to be popped. When configured, popping 4 to 6 MPLS labels will work in all the cases where popping 1 to 3 MPLS labels works. Generally, it will also interact with features the same way as popping 1 to 3 MPLS labels unless specified in the Limitations section. The TOI for MPLS pop for 1 to 3 labels can be found here: https://eos.arista.com/eos-4-15-0f/tap-aggregation-mpls-pop/ Platform Compatibility DCS-7020 DCS-7280/R/R2 series DCS-7500/R/R2...

OSPF routes over GRE tunnels

Description Support for installing OSPF routes over GRE tunnels was added in the EOS 4.23.1F release.  Previous to this release, OSPF would not install routes to GRE tunnels. Platform compatibility DCS-7050X DCS-7050X2 DCS-7250X DCS-7300 DCS-7060X DCS-7060X2 DCS-7260X3 CCS-720XP (Starting in EOS 4.22.1F) DCS-7050SX3 (Starting in EOS 4.22.1F) DCS-7010T (Starting in EOS 4.23.0F)   7368 (Starting in EOS 4.23.1F)    vEOS router DPDK mode (MODE=sfe in /mnt/flash/veos-config) DCS-7020 ( Starting EOS 4.24.1F )  DCS-7280CR2 ( Starting EOS 4.24.1F )  DCS-7280R ( Starting EOS 4.24.1F )  DCS-7280R2 ( Starting EOS 4.24.1F )  DCS-7280SR ( Starting EOS 4.24.1F )  DCS-7280SR2 ( Starting EOS 4.24.1F ) ...

7800R3/7500R3/7280R3 MLAG support

Description EOS-4.23.1F added basic MLAG support for 7800R3, 7500R3 and 7280R3 platforms. The MLAG features that are currently supported are: Bridging Routing STP VARP L2 Multicast Starting in EOS-4.24.0F, the following feature is supported: Fast MLAG Unicast Convergence Platform compatibility DCS-7800R3 DCS-7500R3 DCS-7280R3 Configuration Refer to the MLAG basic configuration TOI document, as referenced below, for details on configuring a basic MLAG. Limitations The following limitations exist: Peer link must be configured as a LAG. Specifically, it cannot be a single front panel port. (BUG409958) Fast MLAG unicast convergence is not supported (BUG386201) starting in EOS-4.23.1F. In EOS-4.24.0F this limitation...

Show bgp neighbors history

Description This command stores and displays a list of failed BGP connection attempts for each peer. This may be particularly useful while troubleshooting flappy connections. If dynamic peering is enabled, the failure history will be remembered even after the peers are no longer present. Platform compatibility This feature is supported on all platforms. Configuration Relevant error messages are recorded by default, without any configuration. To clear all messages for a peer or group of peers, though, it is necessary to use the command “clear bgp history”. The syntax for this command is described as: switch#clear bgp [ PEER | PREFIX...

SNMP traps for MAC move, learn, and age events

Description This feature adds three new SNMP traps for MAC move, learn, and age events: aristaMacMove, aristaMacLearn, and aristaMacAge, respectively. These are defined in the ARISTA-BRIDGE-EXT-MIB. Platform compatibility This feature is supported on all platforms. Configuration The aristaMacMove, aristaMacLearn, and aristaMacAge traps are disabled by default. They may be enabled, like all traps, with the “snmp-server enable traps” command. They are grouped under the “bridge” category, so they can all be enabled at once with “snmp-server enable traps bridge”, or they can each be enabled/disabled individually, as shown below: switch(config)#snmp-server enable traps bridge ? arista-mac-age Enable aristaMacAge trap arista-mac-learn Enable...
