Failover and Recovery (SRP 526W, SRP 527W)

An Internet connection can be established via the DSL port or a 3G wireless
modem plugged into the USB port. Refer to
details on compatible 3G USB modem devices.

used to establish a link at a time. Whenever the Internet connection fails, the
Services Ready Platform automatically attempts to bring up another connection
on another interface. This feature is called
connection recovers, the Services Ready Platform automatically attempts to bring

Description
Failover detection works by detecting the physical
connection and/or presence of traffic on the Internet
link. If the link is idle, the Services Ready Platform
attempts to ping a destination. If the ping does not reply,
the Services Ready Platform assumes the link is down
and attempts to fail over to another interface.
The time interval at which the Services Ready Platform
detects the status of the Internet connection. The default
timeout interval is 60 seconds.
A ping target for the Services Ready Platform to use to
detect the status of the Internet connection. By default
the Services Ready Platform pings the Network Time
Protocol (NTP) servers. You may specify a different IP
address as a target here.
