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 configurable fast LLDP frame transmission interval. The mechanism 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 the TLVs are valid, the LLDP agent saves the information and starts an
aging timer. When the TTL value in the Time To Live TLV carried in the LLDP frame becomes zero,
the information ages out immediately.
