This command enables the context to configure Cisco HDLC parameters. Cisco HDLC is an encapsulation protocol that governs information transfer. The protocol specifies a data encapsulation method on synchronous serial links using frame characters and checksums.

This command configures the number of keepalive intervals that must pass without receiving a keepalive packet before the link is declared down. The nodes at the two endpoints of the cHDLC link must be provisioned with the same values.
The no form of this command returns the down-count to the default value.

This command configures the interval, in seconds, used to send periodic keepalive packets. The receiver process expects to receive a keepalive packet every keepalive interval. The link is declared down if the receiver process does not receive a keepalive within the time-out interval. The link is declared up when the number of continual keepalive packets received equals the up-count. The nodes at the two endpoints of the cHDLC link must be provisioned with the same values.
The no form of this command returns the keepalive interval to the default value.

This command configures the number of continual keepalive packets that have to be received in order to declare the link up. The nodes at the two endpoints of the cHDLC link must be provisioned with the same values.
The no form of this command returns the up-count to the default value.
