Configure LLDP

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.
  1. Enable LLDP on the firewall.
    Select
    Network
    LLDP
    and edit the LLDP General section; select
    Enable
    .
  2. (
    Optional
    ) Change LLDP global settings.
    1. For
      Transmit Interval (sec)
      , specify the interval (in seconds) at which LLDPDUs are transmitted. Default: 30 seconds. Range: 1-3600 seconds.
    2. 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.
    3. 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.
    4. 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.
    5. Click
      OK
      .
  3. Create an LLDP profile.
    For descriptions of the optional TLVs, see Supported TLVs in LLDP.
    1. Select
      Network
      Network Profiles
      LLDP Profile
      and
      Add
      a
      Name
      for the LLDP profile.
    2. For
      Mode
      , select
      transmit-receive
      (default),
      transmit-only
      , or
      receive-only
      .
    3. 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
      Device
      Log Settings
      System
      SNMP Trap Profile
      and
      Syslog Profile
      .
    4. For Optional TLVs, select the TLVs you want transmitted:
      • Port Description
      • System Name
      • System Description
      • System Capabilities
    5. (
      Optional
      ) Select
      Management Address
      to add one or more management addresses and
      Add
      a
      Name
      .
    6. 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.
    7. 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.
    8. Click
      OK
      .
    9. 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.
    10. Click
      OK
      .
  4. Assign an LLDP profile to an interface.
    1. Select
      Network
      Interfaces
      and select the interface where you will assign an LLDP profile.
    2. Select
      Advanced
      LLDP
      .
    3. Select
      Enable LLDP
      to assign an LLDP profile to the interface.
    4. 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.
    5. Click
      OK
      .
