Hello.
There are cisco 9300 switches connected via etherchannel.
Service-policy queuing does not work on output. Or statistics are not displayed.
The settings on the switch are identical, traffic and telephony pass through them exactly
and the one in the ACL.
There are hits in the statistics for input the service policy,
But on both switches, the output is generally zero-based,
even in class-default. (0 packets hits)
Even if the traffic does not fall under the match, there should be statistics
for the default class.
Tried and set cos 5, match cos 5 instead of qos-group 3 on both switches.
Why are there no hits? (0 packets hits)?
