Interface Overrun and Underruns - Meaning

[kfarrington]

All, I have a HSSI from LDN-NY (DS3) and I am seeing the following incrementing:-

On the London router HSSI

39100 input errors, 39100 overrun

19368 output errors, 19368 underruns

Please could some claify if this is a real issue and should I get the hardware checked out. I have had a look at the "show int" documentation and I dont find it that clear on how to proceed.

Many thx indeed.

could be due to buffering. Check out this link.

click on the output interpreter and then cut and paste the data from a "sh int" and a "sh buffer".

Hope this helps.
