Gateway: Allows connectivity to the Admin port through the IP cloud (for example,
3.
through the IP Router). The NOC station can now be several IP hops away. Having a
separate Admin Gateway also allows the Admin IP address to reside on the same IP
network (subnet) as the Protected IP address. Leave empty if you do not want the
admin port routed to remote networks.
Configuring Failover Parameters
See "Failover BSCs" on page 1-11 for background information about fail-over operation
of the BSC.
Two BlueSecure Controllers can be configured to provide high-availability redundancy
using the failover mode. In a failover configuration, a primary BSC is connected to a
secondary BSC via the Failover interface. The secondary BSC monitors a periodic
heartbeat signal on the primary. If the secondary does not detect a certain number of
heartbeats from the primary in a specified amount of time, failover occurs and the
secondary assumes all the functions of the primary.
The primary heartbeat signal will cease when the primary BSC: loses link status on the
managed or protected interface; loses power abruptly; is shutdown gracefully; exceeds a
pre-set threshold; crashes due to a software defect. Disconnecting the managed or
protected interface cable will cause a failover.
The secondary BlueSecure Controller becomes active with the same MAC addresses, the
same IP addresses, the same software and patches, the same configuration and the active
connections table as the primary BlueSecure Controller.
Failover supports redundant layer 2 switches on both managed and protected interfaces.
The controllers can be installed in different rooms, buildings and/or data centers.
Note: For best results, the BSCs should be the same platform and must be running the
same revision of system software with the same installed software patches. It is possible to
run failover between mixed BSC platforms. If this is necessary, then match Controllers as
best you can based on user and BSAP counts. For network planning and design, contact
your Bluesocket representative.
