User Manual

Release/Renew: Obtain a new IP address through DHCP release/renew, and log all activity in the output
area at the bottom.
Start Ping: Start a continuous ping to the address in the edit box next to the button. Once the button is
tapped, its name and function will change to Stop Ping. Pings will continue until you tap the Stop Ping
button, move to an SCU window other than Diags or Status, exit SCU, or remove the radio. Note that, if
your device has both a Summit radio and another network adapter active, then pings may go out over the
non-Summit network adapter.
Diagnostics: Attempt to (re)connect to an AP, and provide a more thorough dump of data than is obtained
with (Re)connect. The dump will include radio state, profile settings, global settings, and a BSSID list of
APs in the area.
Save To...: Save the diagnostics output to a file.
3.6 Global Window
Global settings include radio and security settings that apply to all profiles and settings that apply to SCU itself.
An administrator can define and change most global settings on the Global window in SCU. A sample Global
window is shown in Figure 7 below:
Figure 7: Global window
The following radio global settings, which apply to all configuration profiles, can be changed in SCU:
Roam Delta: When Roam Trigger is met, second AP's signal strength (RSSI) must be Roam Delta dBm
stronger than moving average RSSI for current AP before radio will attempt to roam to second AP
Value: 5, 10, 15, 20, 25, 30, 35, or Custom (see note on Custom below the list)
Default: 10
Roam Period: After association or roam scan (with no roam), radio will collect RSSI scan data for Roam
Period seconds before considering roaming
Value: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, or Custom (see note on Custom below the list)
Default: 10
Roam Trigger:
When moving average RSSI from current AP is weaker than Roam Trigger, radio does a
roam scan where it probes for an AP with a signal that is at least Roam Delta dBm stronger
Value: -50, -55, -60, -65, -70, -75, -80, -85, -90, or Custom (see note on Custom below the list)
Default: -75
BG Channel Set: Defines the 2.4 GHz channels to be scanned when the radio is contemplating a roam and
needs to determine what APs are available.
