Features
If signal strength is less than this trigger value, the client looks for a different Access Point with a
stronger signal.
Options are: -50 dBm, -55, -60, -65, -70, -75, -80, -85, -90 dBm or Custom.
Note: Available options may vary by SCU revision.
The amount by which a different Access Point signal strength must exceed the current Access
Point signal strength before roaming to the different Access Point is attempted.
Options are: 5 dBm, 10, 15, 20, 25, 30, 35 dBm or Custom.
The amount of time, after association or a roam scan with no roam, that the radio collects Received
Signal Strength Indication (RSSI) scan data before a roaming decision is made.
Options are: 5 sec, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 seconds or Custom.
Defines the 2.4GHz channels to be scanned for an AP when the radio is contemplating roaming. By
specifying the channels to search, roaming time may be reduced over scanning all channels.
Options are:
Full (all channels)
1,6,11 (the most commonly used channels)
1,7,13 (for ETSI and TELEC radios only)
Custom.
Support for 5GHZ 802.11a channels where support for DFS is required.
Options are: On, Off.
Note: Not supported (always off) in some releases.
ABG radio only. The amount of time the radio will passively scan each DFS channel to see if it will
receive a beacon.
Recommended value is 1.5 times that of the AP's beacon period.
Use this parameter when the
Specifies the channel to be used for an Ad Hoc connection to another client device. If a channel is
selected that is not supported by the by the radio, the default value is used.
Options are:
1 through 14 (the 2.4GHz channels)
36, 40, 44, 48 (the UNII-1 channels)
When set to On and the current connection to an AP weakens, the radio aggressively scans for
available APs.
Aggressive scanning works with standard scanning (set through Roam Trigger, Roam Delta and
Roam Period). Aggressive scanning should be set to On unless there is significant co-channel
interference due to overlapping APs on the same channel.
Options are: On, Off
Use of Cisco Compatible Extensions (CCX) radio management and AP specified maximum
transmit power features.
Optimized –Use Cisco IE and CCX version number, support all CCX features except AP assisted
