[nsp] Catalyst6509 GE interface hang without any indication

[Joe Shen]

Hi,


We are using a Catalyst6509 as distribution layer switch which is
connected to M160 by GE interface( OSPF run on both side)..

Yesterday we noticed that no traffic occur on that GE link at some
special time. 
 When trying to "ping"  the other side on either platform,  no responds
got. 
 But, on either M160 or Catalyst6509 "sh interface"  
showed  no errors information.  When checking syslog, there is no error
record  either.  

We also checked the configuration record for both system, and found
there is no  modification in configuration at the time when
link load becomes zero.

As last resort, we solved this problem by  "shutdown"  GE VLAN interface
on Catalyst6509, and  "no shut" consequently, then everything 
come up. 

But, today another Catalyst6509 of our system hanged on its uplink GE.
We have to restarted the box to solve. Different from the catalyst6509
hanged yesterday, this catalyst6509 have netflow-export enabled for
month.  ( I included the detailed info at the end )

I tried hard to find out the reason but  can't find any information
related on Cisco's site. 



Is there anybody could do me a favor to do some help?

Each word will be highly appreciated.


regards
 
Joe Shen
