DOS Channel—A channelwhere wireless containment i s active. This channel should belongto the country-code
channel(regulatory domain).
Understand ing TotalWatch Mon itoring Features
TotalWatch enablesmonitoring of all channels includingregulatory domain and rare channels.You can select one of
the following scanningmodes for each radio AP.
lscan only the channelsthat belong to the AP’s regulatory domain
lscan channelsthat belongt o all regulatorydomains
lscan allc hannels
Understanding TotalWatchScanning Spectrum Features
TotalWatch scans the following frequencies.
lG-band—2412MHzt o 2472MHz
lJ band—2484 MHz
lA-band—5000-5100Mhz to 5895MHz
lJ-band—4900-4995MHz
Table1 10 list the frequency-to-channelmapping used by TotalWatch.

Understand ing TotalWatc h Channe l Dwell Time
Whenan AP (in am-mode) visits a channel,t heamount of ti met heA P

stays

on that channel is known as the

dwell

time

. The channeldwell time is a variable value based on the following channeltypes.
dwell-time-active-channel—Forchannels where there is wireless activity. Default setting is 500 ms.
dwell-time-reg-domainc hannel—Forchannels that belong to the AP ’s regulatorydomain group (reg-domain) with
no
wireless activity. The default setting is 250 ms.
dwell-time-other-reg-domain-channel—Forchannels that belong to the
all
regulatorydomain group (all-reg-domain)
with
no
wireless activity The default setting is 250 ms.
dwell-time-rare-channel—For channelsin t he raregroup 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.
