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;hold-multiplier 4;interface all {disable;}interface ge-1/1/1;lldp-configuration-notification-interval 30;ptopo-configuration-maximum-hold-time 300;ptopo-configuration-trap-interval 30;transmit-delay 2;}}
You verify operation of LLDP with several show commands:
- show lldp <detail>
- show lldp neighbors interface-name
- show lldp statistics interface-name
- show lldp local-information
- show lldp remote-global-statisitics
You can clear LLDP neighbor information or statistics globally or on an interface:
- clear lldp neighbors interface-name
- clear lldp statistics interface-name
You can display basic information about LLDP with the show lldp detail command:
user@host> show lldp detailLLDP : Enabled
Advertisement interval : 30 Second(s)
Transmit delay : 2 Second(s)
Hold timer : 4 Second(s)
Notification interval : 30 Second(s)
Config Trap Interval : 300 Second(s)
Connection Hold timer : 60 Second(s)
Interface LLDP Neighbor count
ge-1/1/1 Enabled 0
