Multiple Cisco 881 WAN interfaces hang together

Hi

I have a Cisco 2951 at HQ and 9 Cisco 881 at outlets, connection between HQ and outlets is via fibre private network

 

For the pass 1 week, my HQ router and 5 outlet router had hang multiple times.

When the router hangs, the LAN ports are still fully functional, but unable to access outside of the WAN port

 

Attached is a copy of "SH Tech" of the outlet router when it hangs.

Please advice on the cause and resolution. Thx

Hi,Have you checked for bugs

Hi,

Have you checked for bugs on the IOS version that can cause this kind of behaviour ? we had the same kind of issue and a IOS upgrade fixed it.  Just a thought..  worth a try if you haven't done that yet. :)

Please rate helpful answers..
