What is Interface Reset?

[norsyam21]

Hi,

I have Cisco Router 7000 series which connected its Fast Ethernet port to a Cisco Catalyst 2900 series. Currently it facing some problem. When I do a show interface command for Fast Ethernet, I found that the value of Interface Reset is so high.

What does Interface Reset means? Does it indicate physical problem or else?

Thank in advanced.

Interface resets occur as a result of too many different events for it to be relied upon as a sole troubleshooting means. I presume that you have cleared your counters and are not looking at something that happend two years ago. Resets aren't averaged over a recent period of time (like load, etc) but are counted from the last reboot or 'clear counters.'

One common cause for resets is protocol down. The router resets the interface in an attempt to start all over and get protocol negotiated. I also understand that buffer overflows, timeouts, etc. can cause resets.

take it you have checked Autonegotiation and in particular Duplex and Speed parameters on both ends ?, if not try setting to half-duplex then watch counters (having cleared first) then ramp up etc
