7.3.4 Setting the Interval for Sending Heartbeat Packets and the
Number of Times for Retransmitting Heartbeat Packets
If a protocol stack does not detect a TCP connection that has been interrupted for a long time,
you can set the interval for sending heartbeat packets and the number of times for retransmitting
heartbeat packets on the firewall. If the firewall does not receive heartbeat packets from the peer
end in the period (product of the interval for sending heartbeat packets by the number of times
for retransmitting heartbeat packets), it receives an exception notification message and
reestablishes a channel.

retransmitting heartbeat packets at the local end and the peer end. You are advised to set the
same values of the two parameters at the two ends.
heartbeat packets take effect only after dual-system HSB is enabled.
Run the display hot-standby configuration command, and you can view the configuration
of dual-system HSB, including:
– The local and peer IP addresses, port numbers of the channel through which dual-system
HSB data is synchronized.
– The interval for transmitting heartbeat packets, number of times for retransmitting
heartbeat packets.
– The TCP connection status, packet transmission status.
– The dual-system HSB status.
– The status of active and standby devices.
