FEX Stuck in Connecting State

[bret]

Hardware is 6807x with 6800ia, connecting with 10G, using WS-X6904-40G with CVR-CFP-4SFP10G. We recently had two of our fex interfaces trigger an alert Te2/1/13 & Te2/1/14. After investigating I found that an interface in two different fexs dropped into "connecting state".

PACORP-CORE#sh fex 132
FEX: 132        Description: FEX0132     state: online
  FEX version: 15.0(2)EX7
  Extender Model: C6800IA-48FPDR, Extender Serial: FDO1851I0JR
  FCP ready: yes
  Image Version Check: enforced
  Fabric Portchannel Ports: 1
  Fabric port for control traffic: Te1/1/14
  Fabric interface state:
    Po132      - Interface Up.    
    Te1/1/14   - Interface Up.      state: bound      
    Te2/1/14   - Interface Up.      state: connecting

I opened a case with TAC and provided logs, show tech etc. They suggested a shut/no shut on the interface and if that didnt work then reload the fex. After performing both steps the fex port is still in connecting state. Has anyone seen this issue, or have any suggested trouble shooting steps? Since both ports are on the same module and card, im leaning too a module restart, but because other ports on this module are active I am not sure if this is the best course of action.

Thanks in advance for you help,

Bret

Ask TAC to find the root cause and give you a reall answer with real solution.  Shut/no shut, reseating modules and rebooting the device is not a solution. The issue will reapear sooner or later.

If you are not geeting the right answer, esculate the ticket and ask to speak to a suprvisor.

You hit that right on the head Reza! That is exactly what I told my TAC engineer. Next steps is to do just that.
