How to use "show interface" command to figure out the problem?

Hi,

The "show interface" command give out too much information. Such as "5 minutes input rate/ output rate" etc. Can anyone tell me how to identify the interface issue by those info?

Much apprecited!

Learner,

Almost every bit of information that the show interface command provides can be very valuable depending on the situation. Below is a link that will shed some light for you on what all the statistics mean.

I think the 5 minute rate is very helpful in troubleshooting the link. But if the you don't want the clutter or the all info of "show interface" use the "include" keyword to display only what your loooking for.

ex. for errors only:

switch> show interface fa2/0/3 | include errors

0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored

0 output errors, 0 collisions, 0 interface resets

substitute whatever keyword you want in place of "errors"
