Configuring the Negotiation Polling Interval

The polling interval of an interface is the interval at which the interface sends Keepalive packets.

Keepalive packets are used to monitor and maintain the link status. If an interface does not receive any Keepalive packet after five Keepalive intervals, it considers that the link fails.

On a low-speed link, the seconds parameter cannot be set to a small value because it may take a long time to transmit oversized packets on the link. If the interval for sending Keepalive packets is set to a small value, transmission of Keepalive packets is delayed. If an interface does not receive any Keepalive packet from the remote interface after five Keepalive intervals, the interface considers that the link fails.

The negotiation polling interval must be set based on the site requirements.
