Redundancy Groups
Configuring a Redundancy Group
■ Module Authorization Level—This field displays the number of RPs this mod-
ule’s licenses allow it to adopt when it functions on its own. The authorization
level for a redundant module, however, is taken from the level of the primary
module with the most licenses.
■ Protocol Version —When the modules attempt to establish a redundancy group,
each module includes its protocol version in the update messages sent during the
discovery stage. If the modules are not all using the same protocol version, they
cannot establish a group. You should ensure that the modules are running the same
major release version of the software image. (In the software image, WT.XX.YY,
XX indicates the major release version.)
■ Group Authorization Level—This field displays the maximum number of RPs
that the group as a whole can adopt. This number matches the number for the
module with the highest module authorization level. The group authorization
level is not the sum of member’s individual authorization level. In other words,
a redundancy group that includes two primary modules, one with licenses to
adopt 36 RPs and one with licenses to adopt 12, has a group authorization level
of 36.
■ Group Connectivity Status—This field displays one of the following:
• All members connected—This is the normal state for a functioning redun-
dancy group.
• Not all members present—The modules in the group are not all communi-
cating. A module may be unavailable, or the communication links between
the modules may be disrupted.
• n/a—Redundancy is not enabled.
■ Radio Ports adopted by Group—This field displays the total number of RPs
adopted by the redundancy group. This number should equal the total number
of RPs in your network (or that are part of the group). If the number indicates
that RP has not been adopted, investigate the problem.
■ Radio Ports adopted by this module—This field displays the number of RPs that
this module has adopted. If you are viewing the Network Setup > Redundancy
Group > Configuration screen for a module that is running in standby mode, this
field will typically display 0. If the standby module has adopted an RP, determine
which active module has failed.
■ Adoption capacity in group—The group’s adoption capacity is the total number
of RPs that the group is capable of adopting. This number is a sum of the adoption
capacity of every online member of the group. Remember that the group
authorization level sets the maximum for RPs that the group can actually adopt:
a group might be capable of adopting many more RPs than its licenses allow.
■ Adoption capacity on this module—The number of RPs that this module is
capable of adopting.
