Chapter 5: Operation
Figure 5-1. Auto Failover and Manual Recovery.
NOTE: The A/B Switch monitors the WAN connections by PINGing the far side router through the primary WAN
link. If the primary WAN link fails, the A/B Switch auto switches to the backup WAN link. Auto recovery is
disabled in this configuration to prevent flapping.
Figure 5-2. Auto Failover and Auto Recovery.
NOTE: The A/B Switch monitors the WAN connections by PINGing the far side router through the primary WAN
link. If the primary WAN link fails, the A/B Switch auto switches to the backup WAN link. When the
primary WAN link is available again, the A/B Switch auto switches back to the primary.
The monitorip address and monitormac address parameters can be configured to allow the A/B Switch to
monitor connectivity to any device within, or outside of the A/B Switch’s subnet. If monitoring connectivity to a
device on the same subnet as the A/B Switch’s internal Ethernet node, set the A/B Switch’s monitorip address
and monitormac address parameters to the IP address and MAC address of the device being monitored. If
monitoring connectivity to a device on a different subnet/network than the A/B Switch’s internal Ethernet node,
set the A/B Switch’s monitormac address parameter to the MAC address of the gateway router on the A/B
Switch’s subnet, and set the monitorip address parameter to the IP address of the device being monitored. This
allows the PING packet issued by the A/B Switch to be routed through the gateway router to the target device
on a different subnet/network. If you don’t know the MAC address of the target device or the gateway router on
the A/B Switch’s subnet, one method is to open a command prompt window on a P.C. attached to that same
subnet and use the “arp -a” command to retrieve this information from the P.C.’s arp cache (you may need to
PING the IP address first before the entry will appear in the arp cache).
In most network environments, rather than manually configuring the monitormac address, you can configure
the A/B Switch to automatically determine the proper MAC address required for the PING packet. Enter the
monitorip address information as noted above, and then set the monitormac address parameter to 00 00 00 00
00 00. This causes the A/B Switch to issuing an ARP request to the gateway router which will respond with the
appropriate MAC address information needed.
NOTE: When the Auto Switch feature is enabled, manual switching can be performed, but will be overridden by
any auto switching commands that are subsequently issued by the A/B Switch.
