10.2 Link Failure Detection

Link Failure Detection

Link Failure

Detection Time

The bonded SpeedFusion

can detect routing failures on the path between two sites

over each WAN connection. Failed WAN connections will not be used to route VPN

traffic. Health check packets are sent to the remote unit to detect any failure. The more

frequent checks it sends, the shorter detection time, but the higher bandwidth overhead

will be consumed.

When Recommended is selected, a health check packet is sent out every 5 seconds, and

the expected detection time is 15 seconds.

When Fast is selected, a health check packet is sent out every 3 seconds, and the

expected detection time is 6 seconds.

When Faster is selected, a health check packet is sent out every 1 second, and the

expected detection time is 2 seconds.

When Extreme is selected, a health check packet is sent out every 0.1 second, and the

expected detection time is under 1 second.

By default, Recommended is selected.

Important Note

Pepwave proprietary SpeedFusion

used TCP port 32015 and UDP port 4500 for establishing VPN

connections. If you have a firewall in front of the devices, you will need to add firewall rules for these port and

protocols which will allow inbound and outbound traffic pass-through the firewall.
