Configuring LLDP

• 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 4 to 12
The VLAN name will appear similar to the following on the remote device, and in the CLI display
output on the 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.
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 4 to 12
The untagged VLAN ID will appear similar to the following on the remote device, and in the CLI
display output on the device (Refer to show lldp local-info command on page 625).
Port VLAN ID: 99
Syntax: [no] lldp advertise port-vlan-id ports ethernet <port-list> | all
802.3 capabilities
Except for Power-via-MDI information, the device will advertise the following 802.3 attributes when
LLDP is enabled on a global basis:
• Link aggregation information
• MAC/PHY configuration and status
• Maximum frame size
• Power-via-MDI information (not automatically advertised)
Link aggregation
The link-aggregation TLV indicates the following:
• Whether the link is capable of being aggregated
• Whether the link is currently aggregated
• The primary trunk port
Devices advertise link aggregation information about standard link aggregation (LACP) as well as
static trunk configuration.
By default, link-aggregation information is automatically advertised when LLDP is enabled on a
global basis. To disable this advertisement, enter a command such as the following.
