Showing VXLAN Trunk Replication Counters

It is possible to display statistics (incoming and outgoing bytes, packets, etc.) for VXLAN connections (simply called tunnels) that also include the amount of head-end replication (HER) applied to the VXLAN traffic.

Currently, NetVisor OS uses vxlan-loopback-trunk port stats counters for HER replication statistics; therefore, they are cumulative not granular, but may provide a useful tool to measure the amount of vxlan-loopback-trunk bandwidth required in real world conditions.

The tunnel-stats-show command can be used to output all the statistics including the number of head-end replicated packets and the number of head-end replicated bytes. It can also be executed periodically with the show-interval seconds-interval option as shown in the example below:

CLI (network-admin@Spine1) > tunnel-stats-show show-interval 1 format all
