Hi

Per-Port VLAN Configuration Options
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: Appears when the switch is not GVRP-enabled; prevents the port from - or - joining that VLAN.
------------------------------------------
**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.
