In addition to the above changes, a new status was added. This is .1.3.6.1.4.1.161.19.3.1.7.32
(regFailureCount), which is the number of Registration Failures that have occurred at the
AP/BHM. This is a type of Counter32. This statistic was also added to Failure SM List Page.
2.7 AP/SMPRE‐SHAREDKEYAUTHENTICATION
Previously, in a PMP system, the only option for authenticating SMs was through the use of the
BAM Authentication function of Prizm. Now, in Release 9.5, there is a new Authentication Mode
option on the AP called “AP PreShared Key” that is an alternative to BAM Authentication to
prevent unauthorized SMs from registering to an AP.
When the Authentication Mode is set to this option, the AP will act as the authentication server to
its SMs and will make use of a user-configurable pre-shared authentication key. The operator
enters this key on both the AP and all SMs desired to register to that AP. There is also an option
of leaving the AP and SMs at their default setting of using the “Default Key”. Due to the nature of
the authentication operation, if you want to set a specific authentication key, then you MUST
configure the key on all of the SMs and reboot them BEFORE enabling the key and option on the
AP. Otherwise, if you do the AP first, none of the SMs will be able to register.
When using the new 900-MHz Limited AP (restricted to 10 SMs), consider using different keys for
different sectors to force the desired mapping of SMs to APs and avoid SMs being denied service
by their AP's 10-SM limit being filled with the "wrong" SMs.
The authentication key is a 32-character hexadecimal string.
Here is the updated option on the AP GUI:
