Joseph,
It seems to me the use of the ToS bits as discussed by Solie is pretty
antique. RFC 1349 was obsoleted by RFC 2474. You can match on ToS bits in
the router IOS, but not on the Cat3550. I would bet 99.9% of L3 marking is
done using Precedence or DSCP.
Lab wording: "Use an obsolete method of Layer 3 marking that is
inconsistent with latest IOS"
