  Note:

  If the Global Status is set as ShutDown, the Module Status cannot be enabled.

• Module Status—select the administrative status of LLDP module. The list contains:
  • Enabled—indicates that LLDP is enabled in the device and can be enabled port-wise
  • Disabled—indicates that LLDP is disabled in the device and is also disabled on all ports.

• Transmit Interval—enter the time interval at which the LLDP frames are transmitted on behalf of this LLDP agent. The value should be restored from non-volatile storage after a re-initialization of the management system. The value ranges from 5 to 32768 seconds. The default value is 30.
• Holdtime Multiplier—enter the Holdtime Multiplier value, which is the amount of time for which the server should hold the LLDP. This value ranges from 2 to 10 seconds. The default value is 4. The actual time-to-live value used in LLDP frames, as transmitted on behalf of this LLDP agent, can be expressed by the following formula:

  TTL = min (65535, Transmit Interval * Holdtime Multiplier).

  • For example, if the value of Transmit Intervalis 30 and value of Holdtime Multiplieris 4, then value ‘120’ is encoded in TTL field of LLDP header. The value of this object must be restored from non-volatile storage after a re-initialization of the management system.
• Reinitialization Delay—enter the delay from when the port admin status becomes 'disabled' until re-initialization will be attempted. The value of this object must be restored from non-volatile storage after a re-initialization of the management system. This value ranges from 1 to 10 seconds. The default value is 2.

• Tx Delay—enter the delay between successive LLDP frame transmissions initiated by value / status changes in the LLDP local systems objects. This value ranges from 1 to 8192 seconds. The value should be lesser than or equal to (0.25 * Transmit Interval). The default value is 2.
• Notification Interval—enter the time interval during which the local system generates a notification event. In this specific interval, generating more than one notification event is not possible. If additional changes in lldpRemoteSystemsData object groups occur within the indicated throttling period, then these trap events must be suppressed by the agent. The value of this object must be restored from non-volatile storage after a re-initialization of the management system. This value ranges from 5 to 3600 seconds. The default value is 5.

• TxFastInit—this command configures the value used to initialize the txFast variable which determines the number of transmissions that are made in fast transmission mode. This value ranges from 1 to 8. The default value is 1 for LLDP v1 and 4 for LLDP v2.
