A port can learn of a dynamic VLAN through devices that are not aware of
GVRP (Switch "B", above). VLANs must be disabled in GVRP-unaware devices
to allow tagged packets to pass through.
A GVRP-aware port receiving advertisements has these options:
If there is not already a static VLAN with the advertised VID on the
■
receiving port, then dynamically create the VLAN and become a member.
If the switch already has a static VLAN assignment with the same VID as
■
in the advertisement, and the port is configured to Auto for that VLAN,
then the port will dynamically join the VLAN and begin moving that
VLAN's traffic. (For more detail on Auto, see "Per-Port Options for
Dynamic VLAN Advertising and Joining" on page 3-9.)
■ Ignore the advertisement for that VID.
Don't participate in that VLAN.

Note also that a port belonging to a Tagged or Untagged static VLAN has these
configurable options:
