Scenario
After adding a switch to a stack, some ports land in the wrong VLAN or lose trunk configuration unexpectedly.
Recommended Resolution Path
- Audit the stack member role, startup config, and interface inheritance after the join.
- Compare running and startup configuration so you know whether the drift survives reboot.
- Test representative access and trunk ports before reconnecting every endpoint.
- Save and archive the corrected config once port behavior is consistent again.
Technician Notes
Document what changed, what confirmed the fix, and whether the issue points to a broader standards gap worth addressing for the client.
