DOS Channel—A channel where wireless containment is active. This channel should belong to the country-code 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.

scan only the channels that belong to the AP’s regulatory domain

scan channels that belong to all regulatory domains

scan all channels

Understanding TotalWatch Scanning Spectrum Features

TotalWatch scans the following frequencies.

G-band—2412MHz to 2472MHz

J band—2484 MHz

A-band—5000-5100Mhz to 5895MHz

J-band—4900-4995MHz

Table 110 list the frequency-to-channel mapping used by TotalWatch.

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.

dwell-time-active-channel—For channels where there is wireless activity. Default setting is 500 ms.

dwell-time-reg-domainchannel—For channels that belong to the AP’s regulatory domain group (reg-domain) with no wireless activity. The default setting is 250 ms.

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.

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-profilecommand to set the dwell time and scan mode.
