NPE-G1 stops forwarding traffic

Having a 7206vxr w/NPE-G1 connected with gigabit to Cat3550-12g (Layer2 only, ios 12.1(13)EA1a). After some hours the router drops all outgoing traffic to the 3550. Looks like input to the router works. Workaround: clear interface or sh/no sh. Tried both fiber and rj45. Tried different ports. Tried different 3550 switches. 7200 is running 12.3(3a).

Anyone experienced something like this?

Re: NPE-G1 stops forwarding traffic

I have seen this, and the end-all cure for this was a code upgrade. You may want to check with TAC about your issue.

Interesting. Do you know if there is any DDTS for it? Or do you know which code it is fix in?

Tac is involved in this case. Please advise.
