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 you are configuring
■ the member IP address (which is the IP address for the other module in
the redundancy group)
These two settings enable each module to send messages to and receive
messages from the other module. The interface IP address you enter on the
primary module should be the member IP address you enter on the redundant
module. Likewise, the interface IP address you enter on the redundant module
should be the member IP address you enter on the primary module. Table
4-2 provides an example.
Table 4-2. 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 both the primary module and the redundant module. If these settings
do not match, the two 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 a 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 greyed out, and you
cannot configure them (unless you disable redundancy once again).
