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.

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 max-clients

To configure the maximum number of clients per access point, use the config 802.11 max-clients command.

config 802.11{ a | b} max-clients max-clients

Syntax Description

a

Specifies the 802.11a network.

b

Specifies the 802.11b/g network.

max-clients

Configures the maximum number of client connections per access point.

max-clients

Maximum number of client connections per access point. The range is from 1 to 200.

Command Default

None

Examples

The following example shows how to set the maximum number of clients at 22: 


(Cisco Controller) > config 802.11 max-clients 22

Related Commands

show ap config 802.11a


config 802.11b rate

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

Specific AP radio in this data rate.

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.

7.6

This command was introduced in a release earlier than Release 7.6.

Examples

The following example shows how to configure minimum multicast data rate settings: 


(Cisco Controller) > config 802.11 multicast data-rate 12

config 802.11 rate

To set mandatory and supported operational data rates for an 802.11 network, use the config 802.11 rate command.

config 802.11{ a | b} rate { disabled | mandatory | supported} rate

Syntax Description

a

Specifies the 802.11a network.

b

Specifies the 802.11b/g network.

disabled

Disables a specific data rate.

mandatory

Specifies that a client supports the data rate in order to use the network.

supported

Specifies to allow any associated client that supports the data rate to use the network.

rate

Rate value of 6, 9, 12, 18, 24, 36, 48, or 54 Mbps.

Command Default

None

Usage Guidelines

The data rates set with this command are negotiated between the client and the Cisco wireless LAN controller. If the data rate is set to mandatory , the client must support it in order to use the network. If a data rate is set as supported by the Cisco wireless LAN controller, any associated client that also supports that rate may communicate with the Cisco lightweight access point using that rate. It is not required that a client is able to use all the rates marked supported in order to associate.
