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#configure
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 ?
