l DOS Channel: A channel where wireless containment is active. This channel should belong to the countrycode channel (regulatory domain). Understanding TotalWatch Monitoring Features TotalWatch enables monitoring of all channels including regulatory domain and rare channels. You can select one of the following scanning modes for each radio AP: l scan only the channels that belong to the AP's regulatory domain l scan channels that belong to all regulatory domains l scan all channels Understanding TotalWatch Scanning Spectrum Features TotalWatch scans the following frequencies. l G-band-2412MHz to 2472MHz l J-band-2484 MHz and 4900-4995MHz l A-band-5000-5100Mhz to 5895MHz Table 112 list the frequency-to-channel mapping used by TotalWatch. Table 112: Frequency to Channel Mapping Frequency Channel 2412 - 2472MHz (in increments of 5MHz) 1 - 13 2484MHz 14 5100 - 5895MHz (in increments of 5MHz) 20 - 179 4900 - 4995MHz (in increments of 5MHz) 180 - 199 5000 - 5100MHz 200 - 219 Understanding TotalWatch Channel Dwell Time When an AP (in am-mode) visits a channel, the amount of time the AP stays on that channel is known as the dwell time. The channel dwell time is a variable value based on the following channel types. l dwell-time-active-channel: For channels where there is wireless activity. Default setting is 500 ms. l dwell-time-reg-domain channel: For channels that belong to the AP's regulatory domain group (reg- domain) with no wireless activity. The default setting is 250 ms. l dwell-time-other-reg-domain-channel: For channels that belong to the all regulatory domain group (all- reg-domain) with no wireless activity The default setting is 250 ms. l dwell-time-rare-channel: For channels in the rare group where no wireless activity is detected. The default value is 100 ms. Use the rf am-scan-profile command to set the dwell time and scan mode. Dell Networking W-Series ArubaOS 6.4.x | User Guide Wireless Intrusion Prevention | 562
