Network Advanced

A QoS trust boundary changed on one edge while policy-map assumptions on the WAN handoff still reflect the old marking point during a failover rehearsal

Marking is correct in one segment and wrong by the time traffic reaches the WAN policy decision. Normal traffic masked the issue until the standby or alternate path became active under rehearsal conditions.

Network Intermediate

A QoS trust boundary shifts from phone to switchport while one access stack still rewrites DSCP at ingress during a failover rehearsal

The policy is consistent in design and one stack never received the new trust assumption. Normal traffic masked the issue until the standby or alternate path became active under rehearsal conditions.

A QoS policy references the correct class map, but after a subinterface migration it is attached in the wrong direction and voice jitter returns
