Introduction
Redundancy Groups
Remember that standby members support all the same services as the active members,
so you must configure the same wireless settings on all members of a redundancy
group. A simple way to ensure successful failover is to upload one module’s
configuration onto each other module, edit the configuration with module-specific
settings (such as IP address and redundancy group settings), and save the edited
configurations.
A special feature of the Wireless Edge Services zl Module CLI gives you another
option. After establishing a redundancy group, you can access the redundancy group
configuration mode context through the CLI of one of the members of the group.
Any configurations entered from this mode context are pushed to all members of the
group. You can also create a text file offline and copy the file into the CLI in the
redundancy group configuration mode context. The text file can include individual
settings for a particular module and settings that apply to all members of the group.
For instructions on configuring redundancy groups, see Chapter 10: “Redundancy
Groups.”
Note You can configure multiple modules as active members of the group. Because only
one module adopts any given RP, the modules balance RPs among them as described
in Chapter 10: “Redundancy Groups.”
