Show interface command from a 2600XM router

[cboland]

I have a Cisco 2600 series router that is having "input errors" on an Ethernet Interface. When I run the "Show interface" command I get the following output:

Received 733 broadcasts, 0 runts, 0 giants, 0 throttles

77 input errors, 0 CRC, 0 frame, 0 overrun, 77 ignored

0 input packets with dribble condition detected

Is there anyway using the router to find out what is causing these errors?

Thanks.

What do you connect to this ethernet interface and what IOS are you running? You have a bunch of input errors which to be more specific are the ignored errors. The official

definition of this is as follows:

"ignored - Packets dropped because the interface hardware buffers ran low on internal buffers."

Is it possible that you are overrunning this interface with lot of traffic or bursty traffic?

Here is what the documentation says about "ignored " errors:

Number of received packets ignored by the interface because the interface hardware ran low on internal buffers. These buffers are different than the system buffers mentioned previously in the buffer description. Broadcast storms and bursts of noise can cause the ignored count to be increased.

Here is the reference:

Strange, because 733 broadcasts doesn't look like a broadcast storm to me. "bursts of noise"?
