Description
Displays the current ARM channel/power assignment mode.
Shows if 40 MHz mode of operation is allowed on the 5 GHz (802.11a) or 2.4 GHz
(802.11b/g) frequency band only, on all frequency bands, or on neither frequency band.
Shows if the client aware feature is enabled or disabled. When enabled, the AP does
not change channels when there are active clients.
The highest transmit power levels for the AP, from 0-30 dBm in 3 dBm increments.
Higher power level settings may be constrained by local regulatory requirements and
AP capabilities. In the event that an AP is configured for a Max Tx Power setting it
cannot support, this value will be reduced to the highest supported power setting.
The lowest transmit power levels for the AP, from 0-30 dBm, in 3 dBm increments. Note
that power settings will not change if the Assignment option is set to disabled or
maintain.
If enabled, single-radio APs will try to scan across bands for rogue AP detection.
If enabled, Dell APs may change channels to contain off-channel rogue APs with active
clients. This security features allows APs to change channels even if the Client Aware
setting is disabled.
This setting is disabled by default, and should only be enabled in high-security
environments where security requirements are allowed to consume higher levels of
network resources. You may prefer to receive Rogue AP alerts via SNMP traps or syslog
events.
If Scanning is enabled, the Scan Interval defines how often the AP will leave its current
channel to scan other channels in the band.
Off-channel scanning can impact client performance. Typically, the shorter the scan
interval, the higher the impact on performance. If you are deploying a large number of
new APs on the network, you may want to lower the Scan Interval to help those APs find
their optimal settings more quickly. Raise the Scan Interval back to its default setting
after the APs are functioning as desired.
If enabled, the AP initiates active scanning via probe request. This option elicits more
information from nearby APs, but also creates additional management traffic on the
network. Active Scan is disabled by default, and should not be enabled except under the
