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.

Release Modification
8.3 This command was introduced.

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-MHz or 40-MHz mode overrides the globally configured DCA channel width setting (configured by using the config advanced 802.11 channel dca chan-width 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.

Command History

Release Modification
8.3 This command was introduced.

Usage Guidelines

Rx SOP determines the Wi-Fi signal level in dBm at which an access point's radio demodulates and decodes a packet. Higher the level, less sensitive the radio is and smaller the receiver cell size. The table below shows the Rx SOP threshold values for high, medium and low levels for each 802.11 band.

Table 1  Rx SOP Thresholds
802.11 Band High Threshold Medium Threshold Low Threshold

Syntax Description

Command History

Release Modification
8.3 This command was introduced.

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.

Usage Guidelines

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.

8.3 This command was introduced.

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.

Usage Guidelines

When you enable the assisted roaming prediction list, a warning appears and load balancing is disabled for the WLAN, if load balancing is already enabled on the WLAN.

Examples

The following example shows how to enable an 802.11k neighbor list for a WLAN:

(Cisco Controller) >config wlan assisted-roaming neighbor-list enable 1

show assisted-roaming

To display assisted roaming and 802.11k configurations, use the show assisted-roaming command.
