VLAN Configuration
(the default)
with GVRP Enabled
Enabling GVRP causes “No” to display as “Auto”.

Parameter Effect on Port Participation in Designated VLAN
Tagged
Allows the port to join multiple VLANs.
Untagged
Allows VLAN connection to a device that is configured for an untagged
VLAN instead of a tagged VLAN. A port can be an untagged member of
only one port-based VLAN. A port can also be an untagged member of only
one protocol-based VLAN for any given protocol type. For example, if the
switch is configured with the default VLAN plus three protocol-based
VLANs that include IPX, then port 1 can be an untagged member of the
default VLAN and one of the protocol-based VLANS.
No
No
: Appears when the switch is not GVRP-enabled; prevents the port from
- or -
joining that VLAN.
Auto
Auto: Appears when GVRP is enabled on the switch; allows the port to
dynamically join any advertised VLAN that has the same VID
Forbid
Prevents the port from joining the VLAN, even if GVRP is enabled on the
switch.
