Redundancy Groups
High Availability for Wireless Services
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.
Figure 10-2. Stages of Establishing a Redundancy Group
Creating Matching Configurations for the Redundancy
Group
To establish a redundancy group, modules must support the same redundancy group
settings. Typically, you also want all modules in the redundancy group to provide the

You can use one module’s configuration file as a starting point for configuring other
modules. You can transfer the first module’s configuration file to a TFTP or an FTP
