What types of Interface Errors lead to Input/Output Drops/Discards?

Hi All,

I was wondering if anyone knows if all of the following errors would lead to packet drops/discards.

Runts

Giants

Framing Errors

Overrun Errors

Abort Errors

Also, are there any types of interface errors that don't lead to packet drops/discards?

So if all interface errors lead to packet drops/discards, I may not have to poll for multiple OIDs for these errors, but instead just poll for packet drops/discards.

Any insight would be appreciated.

Thanks,

David

Re: What types of Interface Errors lead to Input/Output Drops/Di

ifInDrops do not related to errors.  In fact, ifInDiscards specifically count packets that were discarded without an associated error.  This could be due to a lack of buffer space (e.g. no queue slot), or there was no listener for a TCP connection.  The same is true for ifOutDiscards.

For a consolidated error count, look at ifInErrors and ifOutErrors.  It will depend on the interface/encapsulation type as to what exactly will be counted as an error, but anything that would be an encap-specific error should appear in one of the interface error counters.
