[Use Cases]
sonic(config)# lldp enablelldp mgmt-ip A.B.C.D
[Command] lldp mgmt-ip A.B.C.D
[Purpose] Configure the management IP address of LLDP
[View] System configuration view
[Usage Scenario] Configuring a management address is useful for clearly identifying a device, aiding in network topology mapping, and facilitating network management. When there's a need to advertise a specific management address to neighbors, this command is used for configuration.
[Notes] The management address is carried in the Management Address TLV field of LLDP packets, uniquely identifying a device. By default, it is set to the IP address of the management interface. If the management interface address is not configured, it will default to the Docker container's internal address.
[Use Cases]
sonic(config)# lldp mgmt-ip 10.1.0.15lldp port-id-subtype
[Command] lldp port-id-subtype {macaddress|ifname}
[Purpose] Configure the interface ID type of LLDP
[Parameter]
Parameter | Description |
|---|---|
macaddress | MAC Address |
ifname | Interface Name |
[View] System configuration view
[Usage Scenario] In the LLDP table, the interface IP used in the mode is the device's interface name. To clearly identify interconnected devices, you can configure the interface ID type as a MAC address.
By default, the interface ID type is set to "ifname.".
[Use Cases]
sonic(config)# lldp port-id-subtype macaddress
