Configuring LLDP
QFX Series products 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 identify a variety of devices quickly. The result is 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 on specific interfaces.
To configure basic LLDP options using the CLI:
- Configure the advertisement interval in seconds:
[edit protocols lldp]
user@switch# set advertisement-interval 45 - 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 (LLDP) all - Configure tracing operations for the LLDP protocol:
[edit protocols lldp]
user@switch# set traceoptions file lldptrace
