Configuring a Normal Standby Circuit
For a router at the other end of a hot standby circuit to receive a call, you must
configure the router with a normal standby demand circuit configuration that
includes an IP circuit and caller resolution table.
To do this, navigate to the ppp demand circuit prompt and enter:
standby-mode
<mode>
mode
can be:
For example, to make the demand circuit from-centralbln a normal standby
circuit, enter:
ppp/from-centralbln#
standby-mode standby-normal
In addition to creating a normal standby demand circuit, the circuit’s
connection-mode must be set to collision-slave, for example:
ppp/from-centralbln#
connection-mode collision-slave
Controlling the Failback to the Primary Circuit
If you configured a demand circuit as a hot standby demand circuit, you can
control the failback from the hot standby circuit back to the primary circuit.
To configure how the router transfers from using the hot standby circuit to the
primary circuit, navigate to the ppp demand circuit prompt and enter:
standby-failback-mode
<failback_mode>
demand-normal The circuit operates as a standard demand circuit. This is the default
setting.
standby-normal The circuit is a standby circuit for incoming calls. The router activates
this type of standby circuit manually or by an incoming call.
standby-hot The circuit will back up a failed primary circuit to continue the
transmission of data.
This is a read-only option; you cannot set it manually. The BCC
automatically sets this value when you execute the command
hot-standby
<
demand_circuit_name
> for the primary circuit object.
