Redundancy Groups
High Availability for Wireless Services
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 same wireless services.
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 server and then upload the configuration file to the other
modules in the group. You can then edit module-specific settings (such as IP
addresses for virtual LANs [VLANs] and redundancy group settings) and save
the configuration to the each module’s startup-config. If you later change the
configuration of one module, you must remember to make the same change
to other modules.
Redundancy Group Configuration Mode Context
Alternatively, you can use the redundancy group configuration mode in the
CLI to configure settings that are pushed to all members of the group.
The redundancy group configuration mode is a special configuration mode
available from the enable mode context of the Wireless Edge Services xl
Module CLI. You can only access the redundancy group configuration mode,
however, in these circumstances:
■ The module is a member of a redundancy group.
■ All members of the group are in the Online state.
The redundancy group configuration mode is shared among all members,
so that must the local module must be able to communicate with them.
To enter the redundancy group configuration mode context, enter this com-
mand from the module enable mode context:
ProCurve(wireless-services-C)# redundancy-group-cli-config enable
ProCurve(wireless-services-C)redundancy-cli*#
After accessing the redundancy group configuration mode context, you can
enter almost any command that you can enter from the configuration mode
contexts of an individual module. For example, you can configure a WLAN.
However, when you enter commands, not only the local module, but all
modules in the group, receive the commands. In this way, all members of the
redundancy group enforce consistent settings.
