There's not enough information provided to begin to guess.  What was the order you powered down/up fabric devices?  Which version are you running?  Can APIC see the Switches via LLDP?  How many controllers?  

Robert

I shuttdown the apic from the GUI and gracefully. Then I power off the switches.

Apic version is 5.0

Show lldp command shows nothing. I tested it using 1 apic alone and with apic cluster.

From the APIC CLI run:
acidiag run lldptool in eth2-1

acidiag run lldptool in eth2-2
Robert

Agent instance for device not found 7f

Use ifconfig, and find out the interfaces of the APIC used for fabric uplinks.  Then repeat the command above for them.

Robert

 

if you connect to each APIC, do you see the same behavior on all of them?

Yes. In addition to version 5. I have same problem with vwrsion 4.2.4

any config needed to do for apic faced interfaces?

I exactcly do nothing after fabric discovery. Something missed?
