Channel scanning commands -- scan idle-time

Use scan idle-time to set the service idle timeout timer.

Use undo scan idle-time to restore the default.

Syntax

scan idle-time idle-time

undo scan idle-time

Default

ACs:

In radio view, the service idle timeout timer is 100 milliseconds.

Fat APs:

The service idle timeout timer is 100 milliseconds.

Parameters

idle-time: Specifies the service idle timeout timer in the range of 60 to 5000 milliseconds. The service idle timeout timer cannot be greater than the maximum service period.

Usage guidelines

During a service period, an AP does not begin a new scanning period until the current service period exceeds the scanning period even if the specified service idle timeout expires.

The service idle timeout timer must be a multiple of the beacon interval. The value of the beacon interval is used as the service idle timeout timer if the service idle timeout timer is smaller than the beacon interval.

Examples

# (ACs.) Set the service idle timeout timer to 500 milliseconds for AP 1.

<Sysname> system-view

[Sysname] wlan ap ap1 model WA4320i-ACN

[Sysname-wlan-ap-ap1] radio 1

[Sysname-wlan-ap-ap1-radio-1] scan idle-time 500

# (Fat APs.) Set the service idle timeout timer to 500 milliseconds.

<Sysname> system-view

[Sysname] interface wlan-radio 1/0/2

[Sysname-WLAN-Radio1/0/2] scan idle-time 500

Channel scanning commands -- scan max-service-time

Use scan max-service-time to set the maximum service period.

Use undo scan max-service-time to restore the default.

Syntax

scan max-service-time { max-service-time | no-limit }

undo scan max-service-time

Default

ACs:

In radio view, the maximum service period is 5000 milliseconds.

Fat APs:

The maximum service period is 5000 milliseconds.

Parameters

max-service-time: Specifies the maximum service period in the range of 100 to 5000 milliseconds.

no-limit: Configures the radio to not limit the service period. Specify this keyword to ensure wireless service quality. The AP does not start a scanning period unless the service idle timeout expires.

Usage guidelines

When the maximum service period for an AP is reached, the AP begins a scanning period regardless of whether it has traffic to forward.

Examples

# (ACs.) Set the maximum service period to 3000 milliseconds for AP 1.

<Sysname> system-view

[Sysname] wlan ap ap1 model WA4320i-ACN

[Sysname-wlan-ap-ap1] radio 1

[Sysname-wlan-ap-ap1-radio-1] scan max-service-time 3000

# (Fat APs.) Set the maximum service period to 3000 milliseconds.

<Sysname> system-view

[Sysname] interface wlan-radio 1/0/2

[Sysname-WLAN-Radio1/0/2] scan max-service-time 3000

Channel scanning commands -- scan scan-time

Use scan scan-time to set the scanning period.

Use undo scan scan-time to restore the default.

Syntax

The scanning period is 100 milliseconds.

Parameters

scan-time: Specifies the scanning period in the range of 100 to 5000 milliseconds. The scanning period cannot be greater than the maximum service period.

Usage guidelines

During a service period, the AP scans its working channel and provides wireless services simultaneously for a time period that is the same as the scanning period. When a scanning period expires, the AP starts the next scanning period or a service period.

Examples

# (ACs.) Set the scanning period to 500 milliseconds for AP 1.

<Sysname> system-view

[Sysname] wlan ap ap1 model WA4320i-ACN

[Sysname-wlan-ap-ap1] radio 1

[Sysname-wlan-ap-ap1-radio-1] scan scan-time 500

# (Fat APs.) Set the scanning period to 500 milliseconds.
