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...

Bidirectional PIM on DCS-7020R, DCS-7280E/R/R2, DCS-7500E/R/R2

Bidirectional PIM has information on Bidirectional Protocol Independent Mulicast (PIM). Additional information applicable to DCS-7020R, DCS-7280E/R/R2 and DCS-7500E/R/R2 is documented here. Platform compatibility DCS-7020R DCS-7280E DCS-7280R DCS-7280R2 DCS-7500E DCS-7500R DCS-7500R2 Limitations “Bidirectional PIM” is incompatible with “Dot1x MAB” and “Drop Mac” features. When more than one feature is configured, “Bidirectionl PIM” gets priority followed by “Dot1x MAB” followed by “Drop Mac”. If “Bidirection PIM” is enabled on platforms using Arista Algomatch, ACLs are not supported on routed multicast traffic including sparse-mode PIM
