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.

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.

NAT translations survive failover, but route-map based NAT exemption references an old object group and VPN traffic gets translated unexpectedly
