We are getting an UPDOWN message for the FastEthernet interface of a 3745. The message is issued every 10 minutes (exactly) and indicates the interface is UP. We never see the interface go down. I have done all the obvious things like change the cable, change the switch port it connects to and reload the router. The problem persists. Any ideas?
Can you paste the exact message (wait for 10 min intervals and get the output in your next post). I am trying to figure out what kind of severity the syslog message has. So is this affecting traffic passing through that interface ?
I have finally discovered the cause of this problem, if not a solution - but not before it brought the Fast Ethernet interface down during prime shift. Anyway the culprit was a rougue server running IBM Director. This server was doing a client discovery every 10 minutes hammering the routers ethernet interface with over 2500 packets a second. Why this bought the ethernet interface down needs to be investigated. Note it effected both the production router and a backup router we also tried in the same way.
