A. B. C. D.D.
The correct command sequence to configure LLDP to send the port description time length value (TLV) is A: switch(config-if)#lldp port-description.
LLDP (Link Layer Discovery Protocol) is a vendor-neutral protocol used to discover information about directly connected devices. TLVs (Type-Length-Value) are used by LLDP to carry information about the device, interface, and port. The port description TLV is used to carry a textual description of the port.
To configure LLDP to send the port description TLV, you need to enter the LLDP port description command in the interface configuration mode. The correct syntax for the command is lldp port-description.
Therefore, the correct command sequence is as follows:
- Enter global configuration mode on the switch:
switch(config)# - Enter interface configuration mode for the interface you want to configure:
switch(config)# interface interface-id - Enable LLDP on the interface:
switch(config-if)# lldp enable - Configure the port description TLV:
switch(config-if)# lldp port-description
Note that options B, C, and D are not valid because they do not include the config-if command, which is required to configure an interface-specific parameter such as the port description TLV.
