A network engineer is implementing the Cisco ACI Fabric and notices that the Leaf-1 switch is registered, has an assigned name, but is displayed as inactive in the APIC. After further investigation, it became clear that the leaf switch was recently moved from another Cisco ACI environment. Which action resolves the problem?
A. Clean reload the Leaf-1 switch
B. Define the new TEP address for Leaf-1
C. Change the clock offset from low to high between apic 1 and Leaf-1
D. Modify the ISIS interface peering IP address between apic 1 and Leaf-1
I think should be A.
Configure
Cleanup the Replacement Switch
Once you confirm the switch is in ACI mode, these are the steps to cleanup the replacement switch.
From the new switch console run the command setup-clean-config.sh
Reload (Run the command reload) to cleanup any existing configurations on the switch.
This prevents the issue due to some existing configurations in new switch which conflicts with the current fabric, even if the new switch is configured with another ACI fabric before.
