An engineer needs to configure LLDP to send the port description type length value (TLV). Which command sequence must be implemented?
The correct answer is A. switch(config-if)#lldp port-description
LLDP (Link Layer Discovery Protocol) is a vendor-neutral protocol that allows network devices to advertise information about themselves to other devices on the network. LLDP is used to discover network topology information and to assist with troubleshooting.
The port description TLV is used to advertise a textual description of the port. This information can be useful for network administrators to quickly identify where a particular device is connected in the network. To configure LLDP to send the port description TLV, the engineer should use the following command sequence:
switch(config)# interface <interface-id>
This command sequence will enable LLDP on the specified interface and configure it to send the port description TLV. The TLV will contain the textual description of the port as configured on the switch.
switch#lldp port-description, is incorrect as it does not specify the interface or enter interface configuration mode.
switch(config-line)#lldp port-description, is incorrect as it enters line configuration mode, which is used to configure console or VTY lines, not interface settings.
switch(config)#lldp port-description, is incorrect as it does not specify the interface or enter interface configuration mode, and it configures the global LLDP settings rather than the interface-specific settings.
