Redundancy Groups
Configuring a Redundancy Group
Configuring a Redundancy Group
When you configure a redundancy group, you must define the following on
each module that is a member of the group:
■ the interface IP address for the module that you are configuring
■ the member IP addresses (which are the IP addresses for the other
modules in the redundancy group)
These two settings enable each module to send messages to and receive
messages from other modules. The interface IP address that you enter on the
one module should be the member IP address that you enter on each of the
other modules. Table 10-2 provides an example.
Table 10-2. Configuring IP Addresses for a Redundancy Group
For each module, you must also select either active mode or standby mode.
In addition to defining these settings, you must configure other settings for
the redundancy group, such as the length of the discovery period, the interval
between heartbeats, and the redundancy group ID. These settings must be the
same on all members of the group. If these settings do not match, the modules
cannot establish a functioning redundancy group.
After you define the redundancy group settings, you must enable redundancy.
You must perform this step last; if you try to enable the redundancy group
before you add at least one member, an error message is displayed, telling you
that you must first add a member. If you enable redundancy before configuring
other redundancy settings, the fields for these settings are dimmed, and you
cannot configure them (unless you disable redundancy once again).
