Interface Reset

I find that there is a interface reset on a switch. Why does it happen ? Is that normal ?

Thx

AXISHK -

Interface resets indicate a loss of carrier.  On a LAN interface it could be anything as sinister as a faulting host NIC or cabling to something as simple as the host being shutdown, disconnected or it's NIC being shutdown and brought back up.

If the interface detail above is from the interface in question, I don't think I'd be overly concerned.  There are no other errors on the interface since the switch last reboot.  If you are really worried about it, you could clear the counters on the interface and then check it over a regular interval to see if you can determine when it is happening and then investigate further.

Cheers
