Changing the fast start repeat count

The fast start feature enables a Network Connectivity Device to initially advertise itself at a faster rate for a limited time when an LLDP-MED Endpoint has been newly detected or connected to the network. This feature is important within a VoIP network, for example, where rapid availability is crucial for applications such as emergency call service location (E911).

The fast start timer starts when a Network Connectivity Device receives the first LLDP frame from a newly detected Endpoint.

The LLDP-MED fast start repeat count specifies the number of LLDP packets that will be sent during the LLDP-MED fast start period. By default, the device will send three packets at one-second intervals. If desired, you can change the number of packets the device will send per second, up to a maximum of 10.

Note: The LLDP-MED fast start mechanism is only intended to run on links between Network Connectivity devices and Endpoint devices. It does not apply to links between LAN infrastructure elements, including between Network Connectivity devices, or to other types of links.

To change the LLDP-MED fast start repeat count, enter commands such as the following. 

device(config)#lldp med fast-start-repeat-count 5

The above command causes the device to send five LLDP packets during the LLDP-MED fast start period.
