B.7 RPM2 WI-FI SUPPORT FOR ENTERPRISE NETWORKS.
Enterprise Networks have certain limitations when it comes to Discovering/Programming Radios
in RPM2. There is a 4500 second (75 minute) caching affect inherent to implementation with the
Cisco ® Wi-Fi solution that utilizes the Access Point (AP)/Wireless LAN Controller (WLC)
components. Radios remain 'seen' in RPM2 even after the radio leaves Wi-Fi or is turned off. It
is cached in RPM2 for 4500 seconds. This issue has only been observed with the Cisco AP and
WLC solution; however, other enterprise wireless solutions may observe this caching affect.
Operation with a lower tiered Wi-Fi router that does not operate with a WLC will likely not observe
this behavior. Please see the Software Release Notes for Media Kit SK-019007-001 (14221-3100-
8110) for more information.
B.8 HELPFUL HINTS
B.8.1 Initial Setup and Configuration
Since radio discovery is dependent on if Multicast (mDNS) messages are being received by
RPM2, it is best to keep things as simple as possible. Here are the suggested steps if this is being
setup and configured for the first time.
1. Configure the Access Point with the default personality values provided in Section B.2.
2. Create a basic personality with a single system, set and channel, write it to the radio and
activate it over USB.
3. Complete Sections B.4 through B.6.
If the radio was not discovered in RPM2 but an IP address is displayed on the radio screen as
seen in Figure 12-5, this may mean that the Multicast (mDNS) messages are not making it through
the Access Point. Consult the Access Point's manual and make sure that those messages are
not being filtered out.
B.8.2 Grouping Radios by Service Name
One benefit of using a unique Service Name is that it allows the user to create logical groupings
of radios to reduce the number of radios discovered in RPM2 and help reduce the overhead of
keeping track of which radios have been configured.
For example, if there are 100 radios in Wi-Fi programming mode (see Section B.5) with the same
Service Name, all 100 radios are displayed in the Radio tab after discovery has been completed.
This makes it difficult to select and program multiple radios simultaneously. However, if the
Service Name in the active personality on 16 of the radios are set to something unique like "fire1"
and the RPM2 application Service Name (see Section B.4) is also updated to "fire1," only those
radios with a Service Name of "fire1" are discovered and displayed in the Radio tab.
