[c-nsp] Problems With WS-X6324-100FX-MM on Cisco CAT 6509 Switch

[John Smith]

Greetings, 
   
  Any help on the following issue is appreciated. 
   
  Problem Summary: We have a 24-port 100BaseFX module on Cisco Catalyst 6509 Switch that keeps going unresponsive. The module in question randomly stops passing data/frames. The ports on the module stays up and connected, but there is no activity. There is absolutely nothing in the Switch logs (sh log & sh logg buff 1023). 
   
  We have had 4-5 incidence/instances since this weekend on this exact same issue. The first instance we just reset the card, the 2nd instance we swapped the card, the 3rd instance after swapping the card we reset the card again, the 4th instance we disabled all trunks going to access switches to avoid further outages. 
   
  We currently have a TAC case with Cisco and last night they recommended that we move the new module from current slot to available slot. So, we moved the module from Slot5 to Slot9. The problem still persists. Tonight, we are going to attempt to replace the whole chassis and the supervisor card; which is crazy.
   
  Has anyone run into the above issue? Are there any possibilities that we may be running into some sort of STP issue? The reason that I am pointing to/of any possible STP issue is because even though we have redundant trunks from our 2 CORE Switches (CAT 6509's) to all affected Access Switches (various CAT's), the fail over never works. We have to manually reset the card and then things go back to normal.
