Two aggregation methods are available: Aggregated MAC Protocol Data Unit
(A-MPDU) and Aggregated MAC Service Data Unit (A-MSDU). A-MPDU is performed in
the software whereas A-MSDU is performed in the hardware.
Aggregated MAC Protocol Data
Unit priority levels assigned per traffic type are as follows:
1—Background
2—Spare
0—Best effort
3—Excellent effort
4—Controlled load
5—Video, less than 100-ms
latency and jitter
6—Voice, less than 10-ms
latency and jitter

Allows 80-MHz 802.11ac radios to communicate using two adjacent
40-MHz channels bonded together.
Command Default
The default channel width is
20.
Command History
Release
Modification
7.6
This command was introduced in a release earlier than Release 7.6.
Usage Guidelines
This parameter can be
configured only if the primary channel is statically assigned.
Caution
We recommend
that you do not configure 40-MHz channels in the 2.4-GHz radio band because
severe co-channel interference can occur.
Statically configuring an
access point’s radio for 20- or 40-MHz mode overrides the globally configured
DCA channel width setting (configured by using the
config advanced 802.11
channel dca chan-width-11n command). If you change the static
configuration back to global on the access point radio, the global DCA
configuration overrides the channel width configuration that the access point
was previously using.
Examples
The following example shows
how to configure the channel width for access point AP01 on an 802.11 network
using 40-MHz channels:
To configure the transmit
power level for all access points or a single access point in an 802.11

Command History
Release
Modification
7.6
This command was introduced in a release earlier than Release 7.6.
Usage Guidelines
The supported power levels
depends on the specific access point used and the regulatory region. For
example, the 1240 series access point supports eight levels and the 1200 series
access point supports six levels. See the Channels and Maximum Power Settings
for Cisco Aironet Lightweight Access Points document for the maximum transmit
power limits for your access point. The power levels and available channels are
defined by the country code setting and are regulated on a country-by-country
basis.

detection value is enabled.
Command History
Release
Modification
7.6
This command was introduced in a release earlier than Release 7.6.
Usage Guidelines
If you enable coverage hole
detection, the Cisco WLC automatically determines, based on data that is
received from the access points, whether any access points have clients that
are potentially located in areas with poor coverage.
If both the number and
percentage of failed packets exceed the values that you entered in the
config advanced 802.11
coverage packet-count and
config advanced 802.11
coverage fail-rate commands for a 5-second period, the client is
considered to be in a pre-alarm condition. The controller uses this information
to distinguish between real and false coverage holes and excludes clients with
poor roaming logic. A coverage hole is detected if both the number and
percentage of failed clients meet or exceed the values entered in the
config advanced 802.11
coverage level global and
config advanced 802.11
coverage exception global commands over a 90-second period. The
Cisco WLC determines whether the coverage hole can be corrected and, if
appropriate, mitigates the coverage hole by increasing the transmit power level
for that specific access point.
Examples
The following example shows
how to enable coverage hole detection on an 802.11a network:
To specify the percentage of

network.
b
Specifies the 802.11b/g
network.
global
Configures a global Cisco
lightweight access point specific profile.
cisco_ap
Cisco lightweight access
point name.
percent
802.11a RF utilization
threshold between 0 and 100 percent.
Command Default
The default RF utilization
threshold value is 80 percent.
Command History
Release
Modification
7.6
This command was introduced in a release earlier than Release 7.6.
Examples
The following example shows
how to set the RF utilization threshold for all Cisco lightweight access points
to 0 percent:
(Cisco Controller) >config advanced 802.11 profile utilization global 0
The following example shows
how to set the RF utilization threshold for AP1 to 100 percent:
Specifies the TPC version 1
that offers strong signal coverage and stability.
2
Specifies TPC version 2 is
for scenarios where voice calls are extensively used. The Tx power is
dynamically adjusted with the goal of minimum interference. It is suitable for
dense networks. In this mode, there could be higher roaming delays and coverage
hole incidents.
Command Default
The default TPC version for a
radio is 1.
Command History
Release
Modification
7.6
This command was introduced in a release earlier than Release 7.6.
Examples
The following example shows
how to configure the TPC version as 1 for the 802.11a radio:
Configures
the maximum number of counts for association denial.
count
Maximum number of times that a client is denied for association when the association request that was sent to an access point
does not match any access point on the prediction list. The range is from 1 to 10.
floor-bias
Configures the RSSI bias for access points on the same floor.
RSSI
RSSI bias for access points on the same floor. The range is from 5 to 25. Access points on the same floor have more preference.
prediction-minimum
Configures
the minimum number of optimized access points for the assisted roaming feature.
number_of_APs
Minimum number of optimized access points for the assisted roaming feature. The range is from
1 to 6. If the number of access points in the prediction assigned to the client is smaller than this number, the assisted roaming feature does not work.
Command Default
The default RSSI bias for access points on the same floor is 15 dBm.
Usage Guidelines
802.11k allows a client to request a neighbor report that contains information about known neighbor access points, which can be used for a service set transition. The neighbor list reduces the need for active and passive scanning.
Examples
This example shows how to configure the minimum number of optimized access points for the assisted roaming feature:
> config assisted-roaming prediction-minimum 4
