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.
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
l A-band—5000-5100Mhz to 5895MHz
l J-band—4900-4995MHz
Table 110 list the frequency-to-channel mapping used by TotalWatch.
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.
dwell-time-active-channel—For channels where there is wireless activity. Default setting is 500 ms.
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.
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-profile command to set the dwell time and scan mode.
