All:

What does an ifInDiscard mean on a SVI on a 6500? I did some searching
and
http://www.cisco.com/en/US/tech/tk648/tk362/technologies_q_and_a_item09186a00800b69ac.shtml
said that "ifInDiscards -  These are counted as no buffers as reflected
in the show interfaces command.". The example shows them looking at the
"ignored" counter of the interface.

This issue was brought about when the snmp counter showed a high amount,
but the corresponding interface did not.
