View

Layer 2 Ethernet interface view, port group view

Default level

2: System level

Parameters

all: Advertises all TLVs of the specified type.

basic-tlv: Advertises basic LLDP TLVs.

port-description: Advertises port description TLVs.

system-capability: Advertises system capabilities TLVs.

system-description: Advertises system description TLVs.

system-name: Advertises system name TLVs.

dot1-tlv: Advertises IEEE 802.1 organizationally specific LLDP TLVs.

port-vlan-id: Advertises port VLAN ID TLVs.

protocol-vlan-id [ vlan-id ]: Advertises port and protocol VLAN ID TLVs. The vlan-id argument specifies the ID of the VLAN to be advertised, in the range of 1 to 4094. By default, the vlan-id argument is the least VLAN ID on the port.

vlan-name [ vlan-id ]: Advertises VLAN name TLVs. The vlan-id argument specifies the ID of the VLAN to be advertised in the range of 1 to 4094. By default, the vlan-id argument is the least VLAN ID on the port.

dot3-tlv: Advertises IEEE 802.3 organizationally specific LLDP TLVs.

link-aggregation: Advertises link aggregation TLVs.

mac-physic: Advertises MAC/PHY configuration/status TLVs.

max-frame-size: Advertises maximum frame size TLVs.

power: Advertises power via MDI TLVs and power stateful control TLVs.

med-tlv: Advertises LLDP-MED TLVs.

capability: Advertises LLDP-MED capabilities TLVs.

inventory: Advertises the following TLVs: hardware revision, firmware revision, software revision, serial number, manufacturer name, model name, and asset ID.

location-id: Advertises location identification TLVs.

civic-address: Inserts the normal address information about the network device in location identification TLVs .

device-type: Sets a device type value, in the range of 0 to 2.

country-code: Sets a country code, corresponding to ISO 3166.

{ ca-type ca-value }&<1-10>: Configures address information, where ca-type represents the address information type, in the range of 0 to 255, ca-value represents address information, a string of 1 to 250 characters, and &<1-10> indicates that you can enter up to 10 parameters.

elin-address: Inserts telephone numbers for emergencies in location identification TLVs.

tel-number: Sets the telephone number for emergencies, a string of 10 to 25 characters.

network-policy: Advertises network policy TLVs.

power-over-ethernet: Advertises extended power-via-MDI TLVs.

Description

Use lldp tlv-enable to configure the types of advertisable TLVs for a port or all ports in a port group.

Use undo lldp tlv-enable to disable the advertising of specific types of TLVs.

By default, the device can advertise on a Layer 2 Ethernet port all types of LLDP TLVs, except location identification TLVs.

To enable the device to advertise LLDP-MED TLVs, you must first enable it to advertise LLDP-MED capabilities TLVs.

To disable the device from advertising LLDP-MED capabilities TLVs, you must first disable it from advertising other LLDP-MED TLVs.

To disable the device from advertising MAC/PHY configuration/status TLVs, you must first disable it from advertising LLDP-MED capabilities TLVs.

If you enable the device to advertise LLDP-MED capabilities TLVs, you also enable it to advertise MAC/PHY configuration/status TLVs.

To enable the device to advertise multiple types of TLVs, you can execute the lldp tlv-enable command repeatedly without the all keyword specified.

Examples

# Enable the device to advertise link aggregation TLVs of the IEEE 802.3 organizationally specific TLVs on Ethernet 1/0/1.
