Redundancy Groups
Configuring a Redundancy Group
2. Assign RPs to the modules that should adopt them. Record the Ethernet MAC
addresses for the RPs in a table such as Table 10-3 on page 10-26.
3. On every module in the redundancy group, configure the redundancy settings
and enable redundancy. Verify that all members are connected.
4. On every active module in the redundancy group, set the adoption preference ID
that you assigned that module in step 1. (See “Configure an Adoption Preference
for the Module” on page 10-27.)
5. Have one module adopt all the RPs.
For example, you could wait to set the country code on the other modules until
after the specified module has adopted all RPs. Or you could shutdown the other
modules until after the RPs have become adopted.
You can also push all RPs toward a single module by setting that module’s ID
as the ID in the radio adoption default configurations on all modules. Every time
that a new RP is added to the network, that RP is adopted by the same module
so you know where to look for it.
6. Access the Network Setup > Radio screen on the module that has adopted the
RPs. Set the correct adoption preference ID for each RP, as explained in
“Configure an Adoption Preference for Targeted Radios” on page 10-27.
For each RP, match the ID for the module that should adopt that RP. You can set
the ID for multiple radios at the same time: press the
Ctrl key, select the radios,
and click the Edit button.
For example, your Wireless LAN System includes these components:
• one Wireless Edge Services zl Module with adoption preference ID 10,
acting in active mode
• one Redundant Wireless Services zl Module with adoption preference ID
20, acting in active mode
• ten RP 230s that should be adopted by the primary module
• five RP 220 that should be adopted by the redundant module
You have the primary module adopt the 15 RPs. You select the 20 RP 230 radios
(two for each RP) and assign them adoption preference ID 10. Then you select
the 10 RP 220 radios at assign them adoption preference ID 20.
7. Copy the targeted radio configurations to every active module in the network.
You can use the redundancy group configuration mode context to speed this
process. For example, you could view the running-config of the module that
adopted the RPs and copy the radio configurations. Then paste these commands
in the global configuration mode context of the redundancy group configuration
mode.
