lldp message-transmission transmit-delay

Function

The lldp message-transmission transmit-delay command sets the delay for sending LLDP packets to the neighbor node.

The undo lldp message-transmission transmit-delay command restores the delay for sending LLDP packets to the neighbor node to the default value.

Format

lldp message-transmission transmit-delay interval

undo lldp message-transmission transmit-delay

Parameters

Parameter Description Value

interval

Specifies the delay for sending LLDP packets to the neighbor node.

The value ranges from 1 to 8192, in seconds. The default value is 2.

Default Level

2: Configuration level

Usage Guidelines

Both the LLDP packet sending interval and delay should be shorter than the time that device information is held in neighbors (TTL). Otherwise, the neighbor device cannot receive the LLDP packets sent by the FW after the information about the FW ages on the neighbor device. And TTL = Min (65535, (interval x hold)), so when adjusting the value of Interval between sending LLDP packets, delay in sending LLDP packets, or hold time multiplier of device information on neighbors, you should consider the other values because they are restricted.

The LLDP transmission interval must be set properly and adjusted according to network loads.

  • A large value reduces the LLDP packet transmission frequency. This helps save system resources. However, if the value is too large, the device cannot notify neighbors of its status in a timely manner, and the NMS cannot discover the network topology changes in real time.
  • A short interval increases the LLDP packet transmission frequency and enables the NMS to discover network topology changes in real time. However, if the interval is too short, LLDP packets are exchanged frequently, increasing the system load.
  • The default value is recommended.

Example

# Set the delay for sending LLDP packets to the neighbor node to 10 seconds.
