Parameter seconds: Time interval for the interface to send keepalive packet in seconds. The value ranges from 0 to 32767 and defaults to 10. If the value is set to 0, keepalive packet will not be sent.

Description Use the timer hold command to set the timer to send keepalive packet.

Use the undo timer hold command to restore the default value, or 10 seconds.

If the timer is set to 0 seconds, this means keepalive packets will not be sent out.

On slow links, the seconds argument must not be too small. As a slow link takes long to transmit large packets, this may cause the sending and receiving of keepalive packet to be postponed. If an interface does not receive keepalive packet from the peer device for many keepalive periods, it regards the link to be bad. If this period exceeds the value specified by the seconds argument, the link will be shut down.

When the interfaces are configured with PPP, the same keepalive interval should be configured on both sides of the link.

Example # Set the period to send keepalive packet on interface Serial 1/0 to 20 seconds.
