Configuring LLDP LLDP Configurations
Configuration Guide
363
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.
