Default behavior is that tag nesting is disabled (off) for all VLAN IDs.
Tag push operations apply to egress frames only when the port is configured to
transmit tagged frames for the associated VLAN. Tag nesting operations apply only to
ingress frames that contain a VLAN tag. Tag nesting operations are applied after
classification to a QoS profile.
The DiffServ and RED functions are not performed by ATM ports when frames
contain nested tags (more than one tag).
Generic VLAN Registration Protocol Functions
The Generic VLAN Registration Protocol (GVRP) is not supported on ATM module
ports, so the following command will not work if you specify an ATM port:
config gvrp {listen | send | both | none] ports <portlist>
Configuring Forwarding Database Attributes
ATM ports support all of the existing ExtremeWare forwarding database (FDB)
commands. For more information on these commands, see the ExtremeWare Software
User Guide.
