Appropriate PR in master #1600
What I did
Added possibility to calculate Priority Group drop packet counters
Why I did it
Need to merge feature from master to 201911
How I verified it
Make sure all entries for forwarding have been correctly established, ARP, routing, neighbor, …
Let’s say it’s Ethernet8, using the following command:
and then save config and reload config.
Send packets from host A to host B, make sure the DSCP is 3.
You should be able to observe discard on PG 3 soon.
