The link layer protocols such as PPP, FR, and HDLC adopt a polling timer to check the status
of a link. Configure identical polling interval on the both ends.
By default, the pooling interval is 10 seconds. If it is set to 0, then link detection is prohibited.
The polling interval can either use the default setting or be adjusted as required. If the network
delay is longer or the congestion degree is higher, you can increase the polling interval
appropriately to decrease the network flapping.
