Cisco ACI Fabric Discovery issue

[Va.8427]

Hi there

I have one ACI fabric with some configuration done. When i shutdown whole Fabric including APIC Cluster and all switches. Then i power on all them again. All switches remain in Inactive status. Can somebody tell me why?

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?

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

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.

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

[Va.8427]

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?
