6-15

Parameter

seconds: Specifies the interval for sending Keepalive packet to the remote end through

ISAKMP SA. It can be set to a value in the range 20 to 28800.

Description

Use the ike sa keepalive-timer interval command to configure the interval for sending

Keepalive packet to the remote end through ISAKMP SA.

Use the undo ike sa keepalive-timer interval command to disable the function.

By default, this function is disabled.

This command is used to configure the interval for sending Keepalive packet to the

remote end through ISAKMP SA. IKE maintains the link state of the ISAKMP SA by

using the Keepalive packet. In general, if a timeout is configured at the remote end by

using the ike sa keepalive-timer timeout command, an interval for sending Keepalive

packet must be configured at the local end. When the remote end in the configured

timeout time does not receive the Keepalive packet, the ISAKMP SA with the TIMEOUT

flag and the IPSec SA corresponding to it will be deleted, and otherwise the ISAKMP

SA without the TIMEOUT flag will be marked as TIMEOUT. Thus the configured timeout

should be longer than the interval for sending the Keepalive packet during

configuration.

Related command: ike sa keepalive-timer timeout.

Example

# Configure the interval as 20 seconds for the local end to send Keepalive packet to the

remote end.
