Yes particulary with quotes like this, that show up on a few google

"Q. Does the FWSM support traffic shaping?

A. Traffic shaping is supported via the Catalyst 6500 line cards, which
provide the VLAN interfaces to the FWSM.

Q. Does the FWSM support QoS mechanisms and rate limiting?

A. Yes, it supports all Catalyst 6500 QoS capabilities."
