Configuring LLDP (CLI Procedure)
EX-series switches use Link Layer Discovery Protocol (LLDP) and Link Layer Discovery Protocol Media Endpoint Discovery (LLDP-MED) to learn and distribute device information on network links. The information allows the switch to quickly identify a variety of devices, resulting in a LAN that interoperates smoothly and efficiently.
The LLDP protocol cannot be enabled by issuing the set protocols lldp statement at the edit hierarchy level. Enable the LLDP protocol by configuring it on all interfaces or specific interfaces.
To configure basic LLDP options using the CLI:
- Configure the advertisement interval in seconds
to specify the frequency at which LLDP advertisements are sent:
[edit protocols lldp]
user@switch# set advertisement-interval 45 - Configure the frequency in seconds at which LLDP
advertisements are sent from the switch in the first second after
it has detected an LLDP-capable device:
[edit protocols lldp]
user@switch# set fast-start 8 - Specify the multiplier used in combination with
the advertisement-interval value to determine the length
of time LLDP information is held before it is discarded:
[edit protocols lldp]
user@switch# set hold-multiplier 5 - Configure LLDP on all interfaces or on a specific
interface:
[edit protocols lldp]
user@switch# set interface all - Configure tracing operations for the LLDP protocol:
[edit protocols lldp]
user@switch# set traceoptions file lldptrace
