Usage Guidelines
Aggregation is the process of grouping packet data frames together rather than transmitting them separately. 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
7—Network control
all—Configure all of the priority levels at once.
Note
Configure the priority levels to match the aggregation method used by the clients.

config 802.11 chan_width
To configure the channel width for a particular access point, use the config 802.11 chan_width command.
Allows the radio to communicate using only 20-MHz channels.
Choose this option for legacy 802.11a radios, 20-MHz 802.11n radios, or 40-MHz 802.11n radios that you want to operate using only 20-MHz channels.
40
Allows 40-MHz 802.11n radios to communicate using two adjacent 20-MHz channels bonded together.
Command Default
The default channel width is 20.
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.

Configure Advanced 802.11 Coverage Commands
Use the config advanced 802.11 coverage commands to configure coverage hole detection settings on supported 802.11 networks.
If you enable coverage hole detection, the controller 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 controller 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
This example shows how to enable coverage hole detection on 802.11a network:
> config advanced 802.11a coverage enable

Usage Guidelines
The rssi value that you enter is used to identify coverage holes (or areas of poor coverage) within your network. If the access point receives a packet in the data or voice queue with an RSSI value that is below the value that you enter, a potential coverage hole has been detected.
The access point takes RSSI measurements every 5 seconds and reports them to the controller in 90-second intervals.
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 controller 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.
