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: “Redun-
dancy 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.”
