Displays the information related to the LLDP neighbors detected on the specified port or ports.
| all | Specifies all ports on the switch. |
| port_list | Specifies one or more ports or slots and ports. |
| detailed | Shows detailed information on the neighbors. |
N/A.
You must use the detailed parameter to display detailed information about the received LLDP TLVs.
The following example displays LLDP neighbor information for all switch ports:
