5.2 Failover/Load Balance
The MBR1000 can establish an uplink via the ethernet WAN port or any modems
plugged into the USB or ExpressCard ports. Although all of these devices may
be plugged in, only one of them establishes a link at a time unless load balancing
is enabled. If the WAN connection fails the router will automatically attempt to
bring up a new link on another device. This feature is called failover. You can
also manually disconnect and re-connect specific ports using icons in the
Control column. The priority table can be saved permanently via the Save
button. Priority changes take effect immediately even if they are not saved.
5.2.1
Ethernet WAN Failure Detection
WAN failure detection works by detecting the presence of traffic on the ethernet
WAN link. (Note that this only applies to the ethernet WAN link, not the
modems.) If the link is idle for too long the router will attempt to ping a target IP
address. If the ping does not reply, the router assumes the link is down and
attempts to fail over to a modem.
Enable.
This enables failure detection on the Ethernet link. Even when this is
disabled, unplugging the Ethernet cable at the WAN port will trigger failover to a
modem.
Timeout.
Enter in this field the length of time that the ping target may be unre-
sponsive before the MBR1000 will switch to the next failover connection.
Enable Ping on Idle.
When enabled, the router will send a ping after the link idle
timeout. If the ping gets a reply, the router will restart the idle timer, otherwise it
will failover to a modem.
Ping Target.
The default ping target is the rout
er‟s gateway. You may specify a
different IP address as a target here.
Enable Failback.
This enables the Ethernet WAN connection to be monitored
for usability. If the connection is usable, other WAN connections are discon-
nected and the Ethernet WAN connection is used exclusively.
