[nsp] Catalyst6509 GE interface hang without any indication

[Todd, Douglas M.]

Just some considerations:


1) do a {sh log}
This might help with the debugging situation. Pay attention to the nvram log
and the Active NMP log. They may help you.
2)If I understand the problem correctly you have a GIG E hang - not pass any
traffic? 
	you have the following: M160-GIG port->port GIG 6500, right?
3) These devices are not trunking (just to make sure)
	A: not channeling
	b: not running udld (see 3)
	c: Trunking on the port is off

3) Are you running udld on the 6500 or on the m160?
	Sounds like a udld problem where you are xmit on side tx on the
other. This can keep the port up/up and make it seem like it hangs...
	{sh udld}
	{sh udld port x/y}
	
4) do a {show port counters} {sh port x/y} on the 6500 and see if you find
any counters other than the usual mib increasing. You don't have any
align/fcs/xmit/rcv/ drops on the interface?

5) no the next reload you could run a diag complete to check for hardware
issues.

6) What is the state of both interfaces when they are hung? Do the counters
increase? Which ones increase on both sides?

Just some thoughts...
