In Canopy System Release 6.0 and later releases, Canopy radios support VLAN functionality as defined in the 802.1Q specification, except for the following
* protocols:
− GARP GARV
− STP
− MSTP
− GARP GMRP
◦ embedded source routing (ERIF) in the 802.1Q header
◦ multicast pruning
◦ flooding unknown unicast frames in the downlink
As an additional exception, the Canopy AP does not flood downward the unknown unicast frames to the Canopy SM.
