I'm having trouble with QoS marking on a Catalyst 9300 IOS XE, Version 16.08.01aI'm marking traffic on the input of the access-port's vlan and egress queueing based on a marking match on a Trunk port. I'm wondering if the trunk might be my issue?
The marking setup is by ACL ip access-list extended MISSION-CRITICAL permit ip any 10.0.1.1 255.255.255.255 class-map match-any TRANSACTIONAL match access-group name MISSION-CRITICAL policy-map LAN-TAG class TRANSACTIONAL set dscp af21The issue is that when I check via show policy-map interface I see class match packets but no marking stats Vlan20 Service-policy input: LAN-TAG Class-map: TRANSACTIONAL (match-any) 8606 packets Match: access-group name MISSION-CRITICAL QoS Set dscp af21 Class-map: class-default (match-any) 65704 packets Match: anyThis appears to be verified by Netflow data on the WAN egress interface and packet captures. However the egress queuing is registering bytes out in the P3 class but no packets.
