Parameters
agent: Specifies an LLDP agent type. If you do not specify an agent type in Ethernet or management Ethernet interface view, the command configures the types of advertisable TLVs for nearest bridge agents.
nearest-customer: Specifies nearest customer bridge agents.
nearest-nontpmr: Specifies nearest non-TPMR bridge agents.
all: Advertises all TLVs of the specified type. This keyword enables the interface to advertise following TLVs:
All basic LLDP TLVs if the all keyword is specified for basic-tlv.
All IEEE 802.1 organizationally specific LLDP TLVs if the all keyword is specified for dot1-tlv.
All IEEE 802.3 organizationally specific LLDP TLVs if the all keyword is specified for dot3-tlv.
All LLDP-MED TLVs except location identification TLVs if the all keyword is specified for med-tlv.
basic-tlv: Advertises basic LLDP TLVs.
management-address-tlv [ ipv6 ] [ ip-address | interface loopback interface-number ]: Advertises management address TLVs. The ipv6 keyword indicates that the management address to be advertised is in IPv6 format. If you do not specify this keyword, the management address in IPv4 format will be advertised. The ip-address argument specifies the management address to be advertised. The interface loopback interface-number option specifies the management address as the IP address of a loopback interface specified by its number. By default, the following rules apply:
When you execute the lldp tlv-enable command:
For a Layer 2 Ethernet or aggregate interface, the management address is the IPv4 or IPv6 address of the VLAN interface that meets the following requirements:
In up state.
The corresponding VLAN ID is the lowest among the VLANs permitted on the port.
If you specify the ipv6 keyword, the management address is the IPv6 address. If you do not specify the ipv6 keyword, the management address is the IPv4 address.
If none of the VLAN interfaces of the permitted VLANs is assigned an IPv4 or IPv6 address or all VLAN interfaces are down, the MAC address of the port will be advertised.
For a Layer 3 Ethernet interface, the IPv4 or IPv6 address of the port will be advertised when the following conditions exist:
The ip-address argument is not configured.
The specified loopback interface does not have an IPv4 or IPv6 address, or the specified loopback interface does not exist.
If you specify the ipv6 keyword, the management address is the IPv6 address. If you do not specify the ipv6 keyword, the management address is the IPv4 address.
If the port does not have an IPv4 or IPv6 address, the MAC address of the port will be advertised.
For a Layer 3 aggregate interface or management Ethernet interface, the IPv4 or IPv6 address of the port will be advertised when the ip-address argument is not configured.
If you specify the ipv6 keyword, the management address is the IPv6 address. If you do not specify the ipv6 keyword, the management address is the IPv4 address.
If the port does not have an IPv4 or IPv6 address, the MAC address of the port will be advertised.
When you execute the undo lldp tlv-enable command for a Layer 2/Layer 3 Ethernet interface, management Ethernet interface, or Layer 2/Layer 3 aggregate interface:
If you do not specify ip-address, ipv6, and interface loopback interface-number, the port does not advertise any management address TLVs.
If you specify ip-address, ipv6, or interface loopback interface-number, the port advertises the default management address 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.
dcbx: Advertises the DCBX TLVs. This type of TLV is not supported in the current software version.
evb: Advertises the EVB module TLVs. This type of TLV is not supported in the current software version.
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 a VLAN ID in the TLVs to be advertised. The VLAN ID is in the range of 1 to 4094, and the default is the lowest VLAN ID on the port.
vlan-name [ vlan-id ]: Advertises VLAN name TLVs. The vlan-id argument specifies a VLAN ID in the TLVs to be advertised. The VLAN ID is in the range of 1 to 4094, and the default is the lowest VLAN ID on the port. If you do not specify a VLAN ID and the port is not assigned to any VLAN, the PVID of the port is advertised.
management-vid [ mvlan-id ]: Advertises management VLAN ID TLVs. The mvlan-id argument specifies a management VLAN ID in the TLVs to be advertised. The management VLAN ID is in the range of 1 to 4094. If you do not specify this option, the value 0 is advertised, which means that the LLDP agent is not configured with a management VLAN ID.
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 in 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 typical address information about the network device in location identification TLVs .
device-type: Sets a device type value in the range of 0 to 2:
Value 0 specifies a DHCP server.
Value 1 specifies a network device.
Value 2 specifies an LLDP-MED endpoint.
country-code: Sets a country code defined in ISO 3166.
{ ca-type ca-value }&<1-10>: Configures address information. 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. &<1-10> indicates that you can specify up to 10 ca-type ca-value pairs.
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 [ vlan-id ]: Advertises network policy TLVs. The vlan-id argument specifies the voice VLAN ID to be advertised, in the range of 1 to 4094.
power-over-ethernet: Advertises extended power-via-MDI TLVs.
Usage guidelines
Nearest bridge agents are not supported on aggregate interfaces.
You can enable the device to advertise multiple types of TLVs by using this command without the all keyword specified.
If the MAC/PHY configuration/status TLV is not advertisable, none of the LLDP-MED TLVs will be advertised whether or not they are advertisable. If the LLDP-MED capabilities TLV is not advertisable, the other LLDP-MED TLVs will not be advertised regardless of whether or not they are advertisable.
The port and protocol VLAN ID, VLAN name, and management VLAN ID TLVs in IEEE 802.1 organizationally specific LLDP TLVs can be configured only for nearest bridge agents. The configuration can be inherited by nearest customer bridge agents and nearest non-TPMR bridge agents.
