Usage guidelines

This command enables clients that are associated with the same radio to get the guaranteed bandwidth when the network is congested. To set the guaranteed bandwidth, use the bandwidth-guarantee service-template command.

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

Examples

# Enable bandwidth guaranteeing for AP ap1.

<Sysname> system-view

[Sysname] wlan ap ap1 model WA4320i-ACN

[Sysname-wlan-ap-ap1] radio 1

[Sysname-wlan-ap-ap1-radio-1] service-template 1

[Sysname-wlan-ap-ap1-radio-1] bandwidth-guarantee enable

# Enable bandwidth guaranteeing for AP group apgroup1.

Parameters

service-template service-template-name: Specifies a service template by its name, a case-insensitive string of 1 to 63 characters. Make sure the specified service template has been bound to the radio/radio interface.

percent percent: Specifies the percentage of the guaranteed bandwidth to the total bandwidth. The value range for the percent argument is 1 to 100. The total bandwidth represents the maximum bandwidth of the radio. The guaranteed bandwidth represents the minimum bandwidth for the BSS corresponding to the service template.

all: Specifies all service templates.

Usage guidelines

For this command to take effect, make sure the bandwidth guaranteeing feature is enabled.

For all service templates bound to the same radio, the sum of the guaranteed bandwidth percentages cannot exceed 100%.

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

Examples

# Set the guaranteed bandwidth percentage to 30% for service template 1 in radio view.

<Sysname> system-view

[Sysname] wlan ap ap1 model WA4320i-ACN

Predefined user roles

network-admin

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.
