the token bucket mechanism to rate limit LLDP frames. For more information about the token bucket

mechanism, see

ACL and QoS Configuration Guide

LLDP automatically enables the fast LLDP frame transmission mechanism in either of the following

cases:

•

A new LLDP frame is received and carries device information new to the local device.

•

The LLDP operating mode of the LLDP agent changes from Disable or Rx to TxRx or Tx.

The fast LLDP frame transmission mechanism successively sends the specified number of LLDP

frames at a config urable fast LLDP frame tran smission interval. The mech anism helps LLDP

neighbors discover the local device as soon as possible. Then, the normal LLDP frame transmission

interval resumes.

Receiving LLDP frames

An LLDP agent operating in TxRx mode or Rx mode confirms the validity of TLVs carried in every

received LLDP frame. If th e TLVs are valid, the LLDP agent saves the information and starts an

aging timer. The initial value of the agi ng timer is equal to the T TL value in t he Time To Live TLV

carried in the LLDP frame. When the LLDP agent receives a ne w LLDP frame, the aging timer

restarts. When the aging timer decreases to zero, all saved information ages out.
