Recovering a Disconnected Leaf: APIC

[Sureshamahadevappa]

Hi ,

Unfortunately we have disabled all the interfaces connecting from Leaf 101 to towards Spine switch; now we are not able to see leaf 101 node in APIC UI and also we tried the steps given in the link http://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/apic/sw/1-x/troubleshooting/b_APIC_Troubleshooting/b_APIC_Troubleshooting_chapter_01000.html...still we are not able to recover the node ..Please suggest if there are any other steps which we need to follow to enable the interfaces.

Regards,

Hi Suresh,

Are your APICs connected to leaf 101 or a different node? What errors did you see when following the steps in the document you linked?

Maybe it's the easiest to just reset the switch?

Suresh,

Please try the following:

1. Ensure you've unblacklisted (enabled) the ports from the APIC GUI.

2. Log into Leaf101 via console and issue 'setinservce' command.  This requires the leaf version be 11.1(1j) .  If this doesn't work, or the software is older, you can use the erase script instead 'setup-clean-config.sh' from the console CLI.

Hello Suresh,

we are having same issue.

How did you fix authentication issue, we see TACACS server authorizes but this disconnect Leaf switch does not login.

Did you reboot the Leaf switch physically?

Thanks,
