52 Switching Configuration
Link Layer Discovery Protocol
The Link Layer Discovery Protocol (LLDP) feature allows individual interfaces on the switch to advertise
major capabilities and physical descriptions. Network managers can view this information and identify
system topology and detect bad configurations on the LAN.
LLDP has separately configurable transmit and receive functions. Interfaces can transmit and receive
LLDP information.
CLI Examples
Example #1: Set Global LLDP Parameters
Use the following sequence to specify switch-wide notification interval and timers for all LLDP
interfaces.
console(config)#lldp ?
notification-interval Configure minimum interval to
send remote data
change notifications.
timers Configure the LLDP global
timer values.
console(config)#lldp notification-interval 1000
console(config)#lldp timers hold 8 reinit 5
console(config)#exit
Example #2: Set Interface LLDP Parameters
The following commands configure the Ethernet interface 1/g10 to transmit and receive LLDP
information.
console#configure
console(config)#interface ethernet 1/g10
console(config-if-1/g10)#lldp receive
console(config-if-1/g10)#lldp transmit
console(config-if-1/g10)#lldp transmit-mgmt
console(config-if-1/g10)#exit
console(config)#exit
