Configuring Redundancy Failover - Motorola APEX1000 Installation And Operation Manual

Configuring Redundancy Failover

You can configure the following parameters in the Redundancy Failover portion of the
Chassis Redundancy Configuration
Parameter
Force Failover
Status
Redundancy Availability
The APEX1000 reports the status of the 1:1 redundancy system, whether or not
redundancy is available. Note that the APEX can only failover when redundancy is
available; additionally, the heartbeat interface link must be detected for the system to be
available.
Not all configuration parameters are redundant; make certain to define the Gigabit
Ethernet configuration parameters (Enable, IP Address, Subnet Mask, etc.) prior to
enabling Chassis Redundancy on both units. (The same ports must be enabled for each
unit.)
Depending on the current status, the APEX reports the following values:
•
Available – Indicates that both APEXs are healthy, configurations are synchronized,
and there is no fault on either APEX.
•
Protected – Indicates that one APEX is active, and protecting an APEX in a fault
state. For example, if APEX1 is in a fault state and APEX2 is active, APEX1 will
remain protected.
•
Unavailable – Indicates that redundancy is not available, either because the
heartbeat indicates the other APEX is in fault or suspended, or because the APEX
completely fails to receive a heartbeat.
•
Synchronizing – Indicates that redundancy is unavailable until the primary and
secondary configurations are synchronized. (The secondary APEX's configuration is
being synchronized by the primary at this time.)
Synchronizing the Configuration
If the standby APEX detects that the configuration is out of sync, it will synchronize its
configuration from the active APEX.
Some configuration parameters require a reboot. For example, if the secondary APEX is
configured to use CSA encryption algorithm and the primary APEX is configured to use
DCII DES encryption algorithm, the secondary will need to reboot in order to change the
config value. In this case, it may be appropriate to copy the configuration files which are
read at boot up. The APEX-EM will configure the active APEX, which in turn will setup
the standby APEX.
