11.3 LLDP Function Typical Example
Figure 5-1 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:
Switch A(config)# lldp enable
Switch A(config)#interface ethernet 1/4
Switch A(Config-If-Ethernet1/4)# lldp transmit optional tlv portDesc sysCap
Switch A(Config-If-Ethernet1/4)exit
SWITCH B configuration task sequence:
Switch B(config)#lldp enable
Switch B(config)#interface ethernet1/1
Switch B(Config-If-Ethernet1/1)# lldp mode receive
Switch B(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.
