Configure LLDP

Enable LLDP on the firewall.
Select
Network
LLDP
and edit the LLDP General section; select
Enable
.
(
Optional
) Change LLDP global settings.
For
Transmit Interval (sec)
, specify the interval (in seconds) at which LLDPDUs are transmitted. Range is 1 to 3600; default is 30.
For
Transmit Delay (sec)
, specify the delay time (in seconds) between LLDP transmissions sent after a change is made in a TLV element. The delay helps to prevent flooding the segment with LLDPDUs if many network changes spike the number of LLDP changes, or if the interface flaps. The
Transmit Delay
must be less than the
Transmit Interval
. Range is 1 to 600; default is 2.
For
Hold Time Multiple
, specify a value that is multiplied by the
Transmit Interval
to determine the total TTL Hold Time. Range is 1 to 100; default is 4. The maximum TTL Hold Time is 65535 seconds, regardless of the multiplier value.
For
Notification Interval
, specify the interval (in seconds) at which LLDP Syslog Messages and SNMP Traps are transmitted when MIB changes occur. Range is 1 to 3600; default is 5.

Management Address
to add one or more management addresses and
Add
a
Name
.
Select the
Interface
from which to obtain the management address. At least one management address is required if
Management Address
TLV is enabled. If no management IP address is configured, the system uses the MAC address of the transmitting interface as the management address TLV.
Select
IPv4
or
IPv6
, and in the adjacent field, select an IP address from the list (which lists the addresses configured on the selected interface), or enter an address.
Click
OK
.
Up to four management addresses are allowed. If you specify more than one
Management Address
, they will be sent in the order they are specified, starting at the top of the list. To change the order of the addresses, select an address and use the
Move Up
or
Move Down
buttons.

mode.
If you want to create a new profile, click
