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
