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.

Effect on port participation in designated VLAN


Allows the port to join multiple VLANs.

  • 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.


Prevents the port from joining the VLAN, even if GVRP is enabled on the switch.
