Transmit Interval (sec)

Transmit Delay (sec)

Specify the delay time, in seconds, between LLDP transmissions sent after a change is made in a Type-Length-Value (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 1-600; default is 2).

Hold Time Multiple

Specify a value that is multiplied by the Transmit Interval to determine the total TTL hold time (range is 1-100; default is 4).

The TTL hold time is the length of time the firewall will retain the information from the peer as valid. The maximum TTL hold time is 65,535 seconds, regardless of the multiplier value.

Notification Interval

Specify the interval, in seconds, at which syslog and SNMP Trap notifications are transmitted when MIB changes occur (range is 1-3,600; default is 5).

Interface

Name of the interfaces that have LLDP profiles assigned to them.

LLDP

LLDP status: enabled or disabled.

Mode

LLDP mode of the interface: Tx/Rx, Tx Only, or Rx Only.

Profile

Name of the profile assigned to the interface.

Total Transmitted

Count of LLDPDUs transmitted out the interface.

Dropped Transmit

Count of LLDPDUs that were not transmitted out the interface because of an error. For example, a length error when the system is constructing an LLDPDU for transmission.

Total Received

Count of LLDP frames received on the interface.

Dropped TLV

Count of LLDP frames discarded upon receipt.

Errors

Count of Time-Length-Value (TLV) elements that were received on the interface and contained errors. Types of TLV errors include: one or more mandatory TLVs missing, out of order, containing out-of-range information, or length error.

Unrecognized

Count of TLVs received on the interface that are not recognized by the LLDP local agent, for example, because the TLV type is in the reserved TLV range.

Aged Out

Count of items deleted from the Receive MIB due to proper TTL expiration.
