Configuring LLDP
To disable the default advertisement of the system description, issue the following command:
configure lldp ports [all | <port_list>] no-advertise system-description

Configuring LLDP Timers

Once you enable LLDP, the timer values assume the default values. However, if you want to change any
of these default values, use the CLI to configure the relevant timer.
NOTE
The LLDP timers apply to the entire device and are not configurable by port.
When LLDP is disabled or if the link goes down, LLDP is reinitialized. The reinitialize delay is the
number of seconds the port waits to restart LLDP state machine; the default is 2 seconds.
To change the default reinitialize delay period, use the following command:
configure lldp reinitialize-delay <seconds>
LLDP messages are transmitted at a set interval; this interval has a default value of every 30 seconds. To
change this default value, issue the following command:
configure lldp transmit-interval <seconds>
The time between triggered update LLDP messages is referred to as the transmit delay, and the default
value is 2 seconds. You can change the default transmit delay value to a specified number of seconds or
to be automatically calculated by multiplying the transmit interval by 0.25. To change the value for the
transmit delay, issue the following command:
configure lldp transmit-delay [ auto | <seconds>]
Each LLDP message contains a TTL value. The receiving LLDP agent discards all LLDP messages that
surpass the TTL value; the default value is 120 seconds.
The TTL is calculated by multiplying the transmit interval value and the transmit hold value; the
default transmit hold value is 4. To change the default transmit hold value, issue the following
command:
configure lldp transmit-hold <hold>

Configuring SNMP for LLDP

You can send SNMP traps regarding LLDP; the software supports the LLDP MIB. By default, SNMP
LLDP traps are disabled on all ports; to enable LLDP SNMP traps, issue the following command:
enable snmp traps lldp {ports [all | <port_list>]}
The traps are only sent for those ports that are both enabled for LLDP and have LLDP traps enabled.
To disable the LLDP SNMP traps, issue the following command:
disable snmp traps lldp {ports [all | <port_list>]}
