cisco 800 issue!

We are experiencing speed issues to our MPLS  for some time, we had a similar problem last September which meant our MPLS  was unusable, at that time we switched off the Cisco 800 router and the MPLS was fine, switched it back on and it was ok.

At the end of last week the response on the MPLS was unusable again and we have been receiving complaints from the users. We checked out the MPLS and that was fine, rebooted the router which improves the situation.

Today  I switched off the Cisco Router, we had some ping tests running which had been failing badly, as soon as we switched off the Cisco the pings were returned perfectly. We left the router off for 10 mins and then switched the router back on; the responses for now appear to be fine.

However, there is obviously a problem with the Cisco 800 router which is causing excessive next work trouble on our network and seems to be flooding our WGuard and the Global Crossing router

(MPLS/Internet) which is not acceptable. This appears to build up over a period of time.

Likely the router needs a software update.

Either you simplify configuratio to eliminate some buggy features, or cotnact the TAC for help.

Re: cisco 800 issue!

You keep it well ventilated? what does the CPU usage look like (sh proc cpu hist)?  You can always smash it with a hammer .  All kidding aside, sounds like bad hardware.

No, things stop working after few days, and reload fixes it, mean software bug, generally a memory leak.

Re: cisco 800 issue!

IOS already updated and it didn't resolve the issue can you tell me how to check this MPLS bit you are talking about as I am

not cisco expert. But keep in mind it didn't work after a quick reboot have to switch it off for

5 to 10 minute to bring it to life any Idea and if I have to check the memory leak then

how I be able to do it?

Things so being, best is that you open a case with Cisco TAC and rely on their advice.
