Figure 11-1: LLDP Function Typical Configuration Example
In the network topology graph above, the port 1,3 of SWITCH B are connected to port 2,4 of
SWITCH A. Port 1 of SWITCH B is configured to message-receiving-only mode, Option TLV of
port 4 of SWITCH A is configured as portDes and SysCap.
SWITCH A configuration task sequence:
SwitchA(config)# lldp enable
SwitchA(config)#interface ethernet 1/4
SwitchA(Config-If-Ethernet1/4)#lldp transmit optional tlv portDesc sysCap
SwitchA(Config-If-Ethernet1/4)exit
SWITCH B configuration task sequence:
SwitchB(config)#lldp enable
SwitchB(config)#interface ethernet1/1
SwitchB(Config-If-Ethernet1/1)#lldp mode receive
SwitchB(Config-If-Ethernet1/1)#exit
11.4 LLDP Function Troubleshooting
 LLDP function is disabled by default. After enabling the global switch of LLDP, users can
enable the debug switch “debug lldp” simultaneously to check debug information.
 Using “show” function of LLDP function can display the configuration information in global
or port configuration mode.
