VPC Missing VLANs

Hi,

 

We have deployed 2 identical fabrics in 2 different locations, both of them have an external connection to a pair of C4500 via VPC

 

The VPC to the C4500 has 22 VLANs allowed on the connection, it was working fine during staging and when the devices were moved to their final location and powered up again we noticed the VPC was missing 10 VLANS

The configuration is still there, the APIC has no configuration faults, but the VLANs simply won't show up on the trunk!

 

We have tried:

 

  • Detach AEP
  • Detach PG
  • Detach AEP
  • Create New VPC group
  • Delete PD
  • Delete PG
  • Delete Pool
  • Reboot APIC 1
  • Reboot both leafs

the output of the command below shows nothing

moquery -c fvRsPathAtt -f 'fv.RsPathAtt.encap=="vlan-xxx"'

 

The image attached shows those 10 VLANs in the trunk, it should be 22

Do you have endpoints

Do you have endpoints currently using those missing VLANs?
