OS for EX Series Ethernet Switches, Release 10.4
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.

LLDP is enabled on all interfaces by default. If it is disabled, you can enable LLDP by
configuring it on all interfaces or specific interfaces.
To configure LLDP on all interfaces or on a specific interface:
[edit protocols lldp]
user@switch# set interface all
You can specify the number of LLDP-MED advertisements sent from the switch in the
first second after it has detected an LLDP-capable device. The default is 3.
To configure the fast start value:
[edit protocols lldp]
user@switch# set fast-start 8
You can adjust the following settings for LLDP advertisements for troubleshooting or
verification purposes. For normal operations, we recommend that you do not adjust these
settings from the default values.
To specify the frequency at which LLDP advertisements are sent (in seconds):
[edit protocols lldp]
user@switch# set advertisement-interval 45
To determine the length of time LLDP information is held before it is discarded (the
multiplier value is used in combination with the
[edit protocols lldp]
user@switch# set hold-multiplier 5
advertisement-interval value):
