I'm not sure this method is supported on the c3550 but it could be
worth investigating --

The other thing I thought of when I saw your post was to use the
'snmpdelta' utility (bundled with net-snmp) to watch the output
discards counter for the interface(s) you're interested in. This is
essentially the same idea that others have suggested but if you have
any Linux/BSD/*NIX systems you might find 'snmpdelta' is already
installed and ready to go. It can spit results in out tabular form so
the output is easy to work with.

Cheers,
Dale
