Configuring LLDP LLDP Configurations Follow these steps to configure the LLDP feature globally. 1) In the Global Config section, enable LLDP. You can also enable the switch to forward LLDP messages when LLDP function is disabled. Click Apply. LLDP Enable LLDP function globally. LLDP Forwarding (Optional) Enable the switch to forward LLDP messages when LLDP function is disabled. 3) In the Parameter Config section, configure the LLDP parameters. Click Apply. Transmit Interval Enter the interval between successive LLDP packets that are periodically sent from the local device to its neighbors. The default is 30 seconds. Hold Multiplier This parameter is a multiplier on the Transmit Interval that determines the actual TTL (Time To Live) value used in an LLDP packet. TTL is the duration that the neighbor device should hold the received LLDP packet before discarding it. The default value is 4. TTL= Hold Multiplier * Transmit Interval. Transmit Delay Specify the amount of delay from when Admin Status of ports becomes "Disable" until reinitialization will be attempted. The default value is 2 seconds. Reinitialization Delay Specify the amount of delay from when Admin Status of ports becomes "Disable' until reinitialization will be attempted. The default value is 2 seconds. Notification Interval Enter the interval between successive in seconds Trap messages that are periodically sent from the local device to the NMS. The default value is 5. Fast Start Repeat Count Specify the number of LLDP packets that the local port sends when its Admin Status changes from Disable (or Rx_Only) to Tx&RX (or Tx_Only). The default value is 3. In this case, the local device will shorten the Transmit Interval of LLDP packets to 1 second to make it quickly discovered by its neighbors. After the specified number of LLDP packets are sent, the Transmit Interval will be restored to the specified value. User Guide 359
