Redundancy Groups
High Availability for Wireless Services
compare their redundancy group settings to ensure that they are the same.
If the modules are not using the same settings, they cannot establish a
functioning redundancy group.
Online state—If the modules can reach each other and they are using
the same redundancy group settings, they change their status to online.
In this state, a standby module can take over for an active module if the
active module becomes unavailable. However, you must configure the
standby modules to provide wireless services, as explained in “Creating
Matching Configurations for the Redundancy Group” on page 10-9.
If redundancy is not enabled for a module, it is in the disabled state.
Figure 10-2 illustrates the process of establishing a redundancy group
between two modules.
