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.
Select NetworkLLDP 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.
Default: 30 seconds. Range: 1-3600 seconds.
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.
Default: 2 seconds. Range: 1-600 seconds.
For Hold Time Multiple, specify
a value that is multiplied by the Transmit Interval 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.
For 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.
Select NetworkNetwork ProfilesLLDP Profile and Add a Name for
the LLDP profile.
For Mode, select transmit-receive (default), transmit-only,
or receive-only.
Select SNMP Syslog Notification to
enable SNMP notifications and syslog messages. If enabled, the global Notification
Interval is used. The firewall will send both an SNMP
trap and a syslog event as configured in the DeviceLog SettingsSystemSNMP Trap Profile and Syslog
Profile.
For Optional TLVs, select the TLVs you want transmitted:
Port Description
System Name
System Description
System Capabilities
(Optional) Select 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.
Click OK.
Assign an LLDP profile to an interface.
Select NetworkInterfaces and select the interface
where you will assign an LLDP profile.
Select AdvancedLLDP.
Select Enable LLDP to assign
an LLDP profile to the interface.
For Profile, select the profile
you created. Selecting None enables LLDP
with basic functionality: sends the three mandatory TLVs and enables transmit-receive mode.
If you want to create a new profile, click LLDP
Profile and follow the instructions steps above.
