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.

(DWS-3024) #config

(DWS-3024) (Config)#lldp ?

notification-interval

Configure

minimum interval to send remote data

 

change notifications

timers

Configure

the LLDP global timer values.

(DWS-3024) (Config)#lldp notification-interval ?
