Configuring LLDP
24
You can list all of the ports individually, use the keyword to to specify ranges of ports, or a
combination of both. To apply the configuration to all ports on the device, use the keyword all
instead of listing the ports individually. Note that using the keyword all may cause undesirable
effects on some ports. For example, if you configure all ports to advertise their VLAN name, and
the configuration includes ports that are not members of any VLAN, the system will warn of the
misconfigurations on non-member VLAN ports. The configuration will be applied to all ports,
however, the ports that are not members of any VLAN will not send VLAN name advertisements.
802.1 capabilities
Except for the VLAN name, the Dell PowerConnect 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.
PowerConnect(config)#lldp advertise vlan-name vlan 99 ports e 2/4 to 2/12
The VLAN name will appear similar to the following on the remote device, and in the CLI display
output on the Dell PowerConnect device (show lldp local-info).
VLAN name (VLAN 99): “Voice-VLAN-99”
Syntax: [no] lldp advertise vlan-name vlan <vlan ID> ports ethernet <port-list> | all
For <vlan ID>, enter the VLAN ID to advertise.
For <port-list>, specify the ports in one of the following formats:
• PowerConnect B-Series FCX stackable switches – <stack-unit/slotnum/portnum>
You can list all of the ports individually, use the keyword to to specify ranges of ports, or a
combination of both. To apply the configuration to all ports on the device, use the keyword all
instead of listing the ports individually. Note that using the keyword all may cause undesirable
effects on some ports. For example, if you configure all ports to advertise their VLAN name, and
the configuration includes ports that are not members of any VLAN, the system will warn of the
misconfigurations on non-member VLAN ports. The configuration will be applied to all ports,
however, the ports that are not members of any VLAN will not send VLAN name advertisements.
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.
PowerConnect(config)#no lldp advertise port-vlan-id ports e 2/4 to 2/12
The untagged VLAN ID will appear similar to the following on the remote device, and in the CLI
display output on the Dell PowerConnect device (show lldp local-info).
Port VLAN ID: 99
