Example: Configuring LLDP
The following example configures LLDP on interface ge-1/1/1 but disables LLDP on all other interfaces, explicitly
configures the default values for all automatically enabled features,
and configures a value of 30 seconds for the LLDP configuration
notification interval and a value of 30 seconds for the physical
topology trap interval.
[edit]
protocols {
lldp {
advertisement-interval 30;

}
}
You verify operation of LLDP with several show commands:
show lldp <detail>show lldp neighbors interface-nameshow lldp statistics interface-nameshow lldp local-informationshow lldp remote-global-statisitics
You can clear LLDP neighbor information or statistics globally or on an interface:
clear lldp neighbors interface-nameclear lldp statistics interface-name
You can display basic information about LLDP with the show
lldp detail command:
user@host> show lldp detail
LLDP : Enabled
Advertisement interval : 30 Second(s)
