To configure LLDP, and create an LLDP profile, you must be a superuser or device administrator (deviceadmin). A firewall interface supports a maximum of five LLDP peers.
Enable LLDP on the firewall.

and edit the LLDP General section; select
) Change LLDP global settings.
Transmit Interval (sec), specify the interval (in seconds) at which LLDPDUs are transmitted. Default: 30 seconds. Range: 1-3600 seconds.
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
must be less than the
Transmit Interval. Default: 2 seconds. Range: 1-600 seconds.
Hold Time Multiple, specify a value that is multiplied by the
to determine the total TTL Hold Time. Default: 4. Range: 1-100. The maximum TTL Hold Time is 65535 seconds, regardless of the multiplier value.
Notification Interval, specify the interval (in seconds) at which
LLDP Syslog Messages and SNMP Traps are transmitted when MIB changes occur. Default: 5 seconds. Range: 1-3600 seconds.

Optional TLVs, select the TLVs you want transmitted:
to add one or more management addresses and
from which to obtain the management address. At least one management address is required if
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.
IPv6, and in the adjacent field, select an IP address from the drop-down (which lists the addresses configured on the selected interface), or enter an address.
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
