Parameters

channelutilization: Specifies the channel usage-based admission policy.

channelutilization-value: Specifies the maximum channel usage in percentage, in the range of 0 to 100. The maximum channel usage refers to the medium time of the accepted AC-VO and AC-VI traffic to the valid time within a certain time. The valid time refers to the time available for transmitting and receiving data. By default, the maximum channel usage is 65%.

client: Specifies the client-based admission policy.

client-number: Specifies the maximum number of clients allowed to be connected, in the range of 0 to 124. A client is counted as one client if it is using both the AC-VO and AC-VI queues.

Usage guidelines

The CAC policy takes effect only on the AC-VO and the AC-VI queues.

The configuration in radio view takes precedence over the configuration in an AP group's radio view.

Examples

# Configure the channel usage-based admission policy for CAC, and set the maximum channel usage to 70%.

<Sysname> system-view

[Sysname] wlan ap ap1 model WA6320

[Sysname-wlan-ap-ap1] radio 1

Parameters

inbound: Limits the rate of incoming traffic.

outbound: Limits the rate of outgoing traffic.

dynamic: Specifies the dynamic rate limit mode. In this mode, the maximum rate for each client is the total maximum rate divided by the number of clients.

static: Specifies the static rate limit mode. The maximum rate for each client is fixed.

cir cir: Specifies the CIR in Kbps. The value range for the cir argument is 16 to 1700000. This option sets the maximum rate for each client in static rate limit mode and sets the total maximum rate for all clients in dynamic rate limit mode.

min min-cir: Specifies the minimum CIR for a client, in the range of 16 to 1700000 Kbps.

max max-cir: Specifies the maximum CIR for a client, in the range of 16 to 1700000 Kbps. The maximum CIR must be larger than the minimum CIR.

Usage guidelines

For this command to take effect, make sure radio-based client rate limiting is enabled.

You can repeat this command multiple times to limit the rates of both the incoming and outgoing traffic.

If you specify both the minimum and maximum CIRs for dynamic rate limit, the feature operates as follows:

·     If the specified CIR divided by the total number of clients is smaller than the minimum CIR, the minimum CIR takes effect for each client.

·     If the specified CIR divided by the total number of clients is larger than the maximum CIR, the maximum CIR takes effect for each client.

·     If the specified CIR divided by the total number of clients is between the minimum and maximum CIRs, the specified CIR divided by the total number of clients takes effect for each client.

The configuration in radio view takes precedence over the configuration in an AP group's radio view.

Examples

# Configure client rate limiting for radio 1 in radio view: set the CIR to 567 Kbps for incoming traffic of each client and set the CIR to 89 Kbps for outgoing traffic of all clients.

Parameters

inbound: Limits the rate of incoming traffic.

outbound: Limits the rate of outgoing traffic.

dynamic: Specifies the dynamic rate limit mode. In this mode, the maximum rate for each client is the total maximum rate divided by the number of clients.

cir cir: Specifies the CIR in Kbps. The value range for the cir argument is 16 to 1700000. This option sets the maximum rate for each client in static rate limit mode and sets the total maximum rate for all clients in dynamic rate limit mode.

min min-cir: Specifies the minimum CIR for a client, in the range of 16 to 1700000 Kbps.

max max-cir: Specifies the maximum CIR for a client, in the range of 16 to 1700000 Kbps.

static: Specifies the static rate limit mode. The maximum rate for each client is fixed.

cbs cbs: Specifies the CBS in bytes. The value range for the cbs argument is 1 to 268435456. If you do not specify this option, the value of CBS is automatically calculated from the value of CIR.

Usage guidelines

You can repeat this command multiple times to limit the rates of both the incoming and outgoing traffic.

If you specify a minimum CIR, a maximum CIR, or both for dynamic rate limit, the feature operates as follows:

·     If the specified CIR divided by the total number of clients is smaller than the minimum CIR, the minimum CIR takes effect for each client.

·     If the specified CIR divided by the total number of clients is larger than the maximum CIR, the maximum CIR takes effect for each client.

·     If the specified CIR divided by the total number of clients is between the minimum and maximum CIRs, the calculated value takes effect for each client.

Examples

# Configure rate limiting for service template 1:

·     Enable dynamic rate limit for incoming traffic, set the CIR to 567 Kbps, the minimum CIR to 123 Kbps, and the maximum CIR to 500 Kbps.

·     Enable dynamic rate limit for outgoing traffic, set the CIR to 789 Kbps, the minimum CIR to 234 Kbps, and the maximum CIR to 600 Kbps.
