Configuring TotalWatch, Understanding TotalWatch Channel Types and Qualifiers

Page 561 highlights

TotalWatch allows for detecting devices that are running on typical operational channels. Tarpit Shielding provides a better way of containing devices that are deemed unauthorized. Both of these features are discussed in the sections that follow. l Configuring TotalWatch on page 561 l Administering TotalWatch on page 563 l Tarpit Shielding Overview on page 564 l Configuring Tarpit Shielding on page 564 Configuring TotalWatch Dell 802.11n APs and non-11n APs in AM-mode support for TotalWatch is the ability to scan all channels of the RF spectrum, including 2.4-and 5-GHz bands as well as the 4.9-GHz public safety band. TotalWatch also provides 5-MHz granular channel scanning of bands for rogue devices and dynamic scanning dwell times to focus on those channels with traffic. TotalWatch provides an advanced set of features to detect unauthorized wireless devices and a set of customized rules are used to highlight devices that truly pose a threat to the network. TotalWatch is supported on APs deployed in the AM-mode only. TotalWatch provides monitoring support for the entire WLAN spectrum. Dell APs in the AM-mode can monitor the following frequencies: l 2412MHz to 2472MHz in the 2.5GHz band l 5100Mhz to 5895MHz in the 5GHz band. Dell APs in AM-mode can scan the following additional frequencies: l 2484 MHz and 4900Mhz to 5000MHz (J-channels) l 5000 to 5100Mhz If the AP is HT-capable (High Throughput), these frequencies are scanned in the 40MHz mode. Understanding TotalWatch Channel Types and Qualifiers Based on the regulatory characteristics, channels are categorized into the following types: l Reg-domain Channels: A channel that belongs to the regulatory domain of the country in which the AP is deployed. The set of channels that belong to this group is a subset of the channels in the all-reg-domain channel group. l All-reg-domain Channels: A valid non-overlapping channel that is in the regulatory domain of at least one country. The channels in this category belong in the frequency ranges of: n 2412MHz to 2472MHz in the g-band n 5100Mhz to 5895MHz in the a-band. l Rare Channel: Channels that fall into a frequency range outside of the regulatory domain; 2484 MHz and 4900MHz-4995MHz (J-channels), and 5000-5100Mhz. The channels in this group do not belong to any other group. Each of these channel types can have an associated qualifier: l Active Channel: This qualifier indicates that wireless activity is detected on this channel by the presence of an AP or other 802.11 activity such as a probe request. 561 | Wireless Intrusion Prevention Dell Networking W-Series ArubaOS 6.4.x | User Guide

Dell Networking W-Series ArubaOS 6.4.x | User Guide
TotalWatch allows for detecting devices that are running on typical operational channels. Tarpit Shielding
provides a better way of containing devices that are deemed unauthorized. Both of these features are
discussed in the sections that follow.

Configuring TotalWatch
Dell 802.11n APs and non-11n APs in AM-mode support for TotalWatch is the ability to scan all channels of the
RF spectrum, including 2.4-and 5-GHz bands as well as the 4.9-GHz public safety band. TotalWatch also
provides 5-MHz granular channel scanning of bands for rogue devices and dynamic scanning dwell times to
focus on those channels with traffic. TotalWatch provides an advanced set of features to detect unauthorized
wireless devices and a set of customized rules are used to highlight devices that truly pose a threat to the
network.
TotalWatch is supported on APs deployed in the AM-mode only.
TotalWatch provides monitoring support for the entire WLAN spectrum. Dell APs in the AM-mode can
monitor
the following frequencies:
l
2412MHz to 2472MHz in the 2.5GHz band
l
5100Mhz to 5895MHz in the 5GHz band.
Dell APs in AM-mode can
scan
the following additional frequencies:
l
2484 MHz and 4900Mhz to 5000MHz (J-channels)
l
5000 to 5100Mhz
If the AP is HT-capable (High Throughput), these frequencies are scanned in the 40MHz mode.
Understanding TotalWatch Channel Types and Qualifiers
Based on the regulatory characteristics, channels are categorized into the following types:
l
Reg-domain Channels:
A channel that belongs to the regulatory domain of the country in which the AP is
deployed. The set of channels that belong to this group is a subset of the channels in the all-reg-domain
channel group.
l
All-reg-domain Channels:
A valid non-overlapping channel that is in the regulatory domain of at least one
country. The channels in this category belong in the frequency ranges of:
n
2412MHz to 2472MHz in the g-band
n
5100Mhz to 5895MHz in the a-band.
l
Rare Channel:
Channels that fall into a frequency range outside of the regulatory domain; 2484 MHz and
4900MHz-4995MHz (J-channels), and 5000-5100Mhz. The channels in this group do not belong to any
other group.
Each of these channel types can have an associated qualifier:
l
Active Channel:
This qualifier indicates that wireless activity is detected on this channel by the presence of
an AP or other 802.11 activity such as a probe request.
