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.

8.3 This command was introduced.

Usage Guidelines

When you enable Beamforming on the network, it is automatically enabled for all the radios applicable to that network type.

Follow these guidelines for using Beamforming:

  • Beamforming is supported only for legacy orthogonal frequency-division multiplexing (OFDM) data rates (6, 9, 12, 18, 24, 36, 48, and 54 mbps).


    Note

    Beamforming is not supported for complementary-code keying (CCK) data rates (1, 2, 5.5, and 11 Mbps).

  • Beamforming is supported only on access points that support 802.11n (AP1250 and AP1140).

  • Two or more antennas must be enabled for transmission.

  • All three antennas must be enabled for reception.

  • OFDM rates must be enabled.

    If the antenna configuration restricts operation to a single transmit antenna, or if OFDM rates are disabled, Beamforming is not used.

Syntax Description

a

Specifies the 802.11a network.

b

Specifies the 802.11b/g network.

static

Enables the static CAC method for video applications on the 802.11a or 802.11b/g network.

Static or bandwidth-based CAC enables the client to specify how much bandwidth or shared medium time is required to accept a new video request and in turn enables the access point to determine whether it is capable of accommodating the request.

load-based

Enables the load-based CAC method for video applications on the 802.11a or 802.11b/g network.

Load-based or dynamic CAC incorporates a measurement scheme that takes into account the bandwidth consumed by all traffic types from itself, from co-channel access points, and by collocated channel interference. Load-based CAC also covers the additional bandwidth consumption results from PHY and channel impairment. The access point admits a new call only if the channel has enough unused bandwidth to support that call.

Load-based CAC is not supported if SIP-CAC is enabled.

Command Default

Static.

Usage Guidelines

CAC commands for video applications on the 802.11a or 802.11b/g network require that the WLAN you are planning to modify is configured for the Wi-Fi Multimedia (WMM) protocol and the quality of service (QoS) level be set to Gold.

config 802.11{ a | b} cac voice max-bandwidth bandwidth

Syntax Description

a

Specifies the 802.11a network.

b

Specifies the 802.11b/g network.

bandwidth

Bandwidth percentage value from 5 to 85%.

Command Default

The default maximum bandwidth allocated to clients for voice applications on the 802.11a or 802.11b/g network is 0%.

Usage Guidelines

The maximum radio frequency (RF) bandwidth cannot exceed 85% for voice and video. Once the client reaches the value specified, the access point rejects new calls on this network.

CAC commands require that the WLAN you are planning to modify is configured for the Wi-Fi Multimedia (WMM) protocol and the quality of service (QoS) level be set to Platinum.

Before you can configure CAC parameters on a network, you must complete the following prerequisites:

  • Disable all WLANs with WMM enabled by entering the config wlan disable wlan_id command.

  • Disable the radio network you want to configure by entering the config 802.11{a | b}  disable network command.

  • Save the new configuration by entering the save config command.

  • Enable voice or video CAC for the network you want to configure by entering the 
config 802.11{a | b}  cac voice acm enable or config 802.11{a | b}  cac video acm enable commands.

Syntax Description

a

Specifies the 802.11a network.

b

Specifies the 802.11b/g network.

default

Restores Layer 2 client roaming RF parameters to default values.

custom

Configures custom Layer 2 client roaming RF parameters.

min_rssi

Minimum received signal strength indicator (RSSI) that is required for the client to associate to the access point. If the client’s average received signal power dips below this threshold, reliable communication is usually impossible. Clients must already have found and roamed to another access point with a stronger signal before the minimum RSSI value is reached. The valid range is –80 to –90 dBm, and the default value is –85 dBm.

roam_hyst

How much greater the signal strength of a neighboring access point must be in order for the client to roam to it. This parameter is intended to reduce the amount of roaming between access points if the client is physically located on or near the border between the two access points. The valid range is 2 to 4 dB, and the default value is 2 dB.

scan_thresh

Minimum RSSI that is allowed before the client should roam to a better access point. When the RSSI drops below the specified value, the client must be able to roam to a better access point within the specified transition time. This parameter also provides a power-save method to minimize the time that the client spends in active or passive scanning. For example, the client can scan slowly when the RSSI is above the threshold and scan more rapidly when the RSSI is below the threshold. The valid range is –70 to –77 dBm, and the default value is –72 dBm.

trans_time

Maximum time allowed for the client to detect a suitable neighboring access point to roam to and to complete the roam, whenever the RSSI from the client’s associated access point is below the scan threshold. The valid range is 1 to 10 seconds, and the default value is 5 seconds.

Note 

For high-speed client roaming applications in outdoor mesh environments, we recommend that you set the transition time to 1 second.

Command Default

The default minimum RSSI is -85 dBm. The default signal strength of a neighboring access point is 2 dB. The default scan threshold value is -72 dBm. The default time allowed for the client to detect a suitable neighboring access point to roam to and to complete the roam is 5 seconds.

Usage Guidelines

For high-speed client roaming applications in outdoor mesh environments, we recommend that you set the trans_time to 1 second.

config 802.11 multicast data-rate

To configure the minimum multicast data rate, use the config 802.11 multicast data-rate command.

config 802.11{ a | b} multicast data-rate data_rate [ ap ap_name | default]

Syntax Description

data_rate

Minimum multicast data rates. The options are 6, 9, 12, 18, 24, 36, 48, 54. Enter 0 to specify that APs will dynamically adjust the number of the buffer allocated for multicast.

ap_name

default

Configures all APs radio in this data rate.

Command Default

The default is 0 where the configuration is disabled and the multicast rate is the lowest mandatory data rate and unicast client data rate.

Usage Guidelines

When you configure the data rate without the AP name or default keyword, you globally reset all the APs to the new value and update the controller global default with this new data rate value. If you configure the data rate with default keyword, you only update the controller global default value and do not reset the value of the APs that are already joined to the controller. The APs that join the controller after the new data rate value is set receives the new data rate value.
