files, along with settings that apply specifically to the SCU. The Global settings in the table
below can be edited in SCU:
Table C.2 Global Tab
Global Setting Description Value Default
Roam Trigger If RSSI from AP is less than roam
trigger value, radio performs roam scan
or probes for an AP with stronger
signal. dBm: -50, -55, -60, -65,
-70, -75, Custom -75
Roam Delta Amount by which second AP’s RSSI
must exceed the moving average RSSI
for the current AP before the radio will
attempt to roam to a second AP. dBm: 5, 10, 15, 20, 25,
30, 35, Custom 10
Roam Period Following an association or roam scan
(with no roam), the number of seconds
the radio collects RSSI scan data before
considering roaming. Seconds: 5, 10, 15, 20,
25, 30, 35, 40, 45, 50,
55, 60, Custom 10
BG Channel Set Defines the 2.4 GHz channels to be
scanned when the radio is set to roam
and needs to determine what APs are
available. Full (all channels)
1, 6, 11

DFS Channels Reserved Off, On Off
Aggressive Scan When this setting is On and the current
connection to an AP becomes unrelia-
ble, the radio scans for available APs
more aggressively. Aggressive scan-
ning complements and works in con-
junction with the standard scanning
that is configured through the Roam
Trigger, Roam Delta, and Roam Period
settings. It is recommended that
Aggressive Scan is left On unless there
is significant co-channel interference
because of overlapping coverage from
APs on the same channel.
