Per-port static VLAN configuration options example

This example shows the options available to assign individual ports to a static VLAN.

GVRP, if configured, affects these options and the VLAN behavior on the switch.

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 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 or Auto

No: When the switch is not GVRP-enabled; prevents the port from joining that VLAN.

Auto: When GVRP is enabled on the switch; it 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.
