I am facing a rather strange issue. I have a 1841 running c1841-ipbase-mz.124-15.T7.
The log message of "%LINK-3-UPDOWN: Interface FastEthernet0/0, changed state to up" keep showing up every 10minutes or so:
There is no message of the interface going down.
I have rebooted the router and checked that there is no CRC, input and output errrors on the interface. May I know what might have cause this to happen?
