802.1 capabilities

Except for the VLAN name, the RUCKUS device will advertise the following 802.1 attributes when LLDP is enabled on a global basis:

  • VLAN name (not automatically advertised)
  • Untagged VLAN ID

VLAN name

The VLAN name TLV contains the name and VLAN ID of a VLAN configured on a port. An LLDPDU may include multiple instances of this TLV, each for a different VLAN.

To advertise the VLAN name, enter a command such as the following.

device(config)#lldp advertise vlan-name vlan 99 ports e 1/2/4 to 1/2/12

The VLAN name will appear similar to the following on the remote device, and in the CLI display output on the RUCKUS device (show lldp local-info ).

VLAN name (VLAN 99): "Voice-VLAN-99"

Untagged VLAN ID

The port VLAN ID TLV advertises the Port VLAN Identifier (PVID) that will be associated with untagged or priority-tagged frames. If the port is not an untagged member of any VLAN (i.e., the port is strictly a tagged port), the value zero will indicate that.

By default, the port VLAN ID is automatically advertised when LLDP is enabled on a global basis. To disable this advertisement, enter a command such as the following.

device(config)#no lldp advertise port-vlan-id ports e 1/2/4 to 1/2/12

The untagged VLAN ID will appear similar to the following on the remote device, and in the CLI display output on the RUCKUS device (show lldp local-info ).

Port VLAN ID: 99
