  • Cisco Application Policy Infrastructure Controller (APIC)

Known Affected Releases

4.2(3l)

Description (partial)

Symptom:
After a switch replacement, the APIC will no longer be able to run show commands on it, e.g. "fabric 101 show int bri", where "101" is the Node ID of the replaced switch.

The APIC will be able to send the command to the switch, but the return will be empty due to an old SSH key (the one of the old switch).

Conditions:
Switch was replaced and the /home/<user>/.ssh/known_hosts file still contains SSH key of the old switch.
