The configuration in AP view takes precedence over the configuration in AP group view. If you execute the undo command in AP view, the backup AC specified in AP group view will be used.

Executing the undo command also terminates the backup CAPWAP tunnel.

Examples

# Specify a backup AC for AP ap1.

<Sysname> system-view

[Sysname] wlan ap ap1 model WA6320

[Sysname-wlan-ap-ap1] backup-ac ip 192.168.1.1

# Specify a backup AC for AP group group1.

<Sysname> system-view

[Sysname] wlan ap-group 1

[Sysname-wlan-ap-group-1] backup-ac ip 192.168.1.1

wlan tunnel-preempt

Use wlan tunnel-preempt enable to enable master CAPWAP tunnel preemption.

Use wlan tunnel-preempt disable to disable master CAPWAP tunnel preemption.

Use undo wlan tunnel-preempt to restore the default.

Syntax

wlan tunnel-preempt { disable | enable }

undo wlan tunnel-preempt

Default

In AP view, an AP uses the configuration in AP group view. If no configuration exists in AP group view, the AP uses the configuration in global configuration view.

In AP group view, an AP uses the configuration in global configuration view.

In global configuration view, master CAPWAP tunnel preemption is disabled.

Usage guidelines

When this feature is enabled, the backup CAPWAP tunnel will become the master tunnel after 10 minutes if the backup AC has higher AP connection priority than the master AC.

When this feature is disabled, the backup CAPWAP tunnel becomes the master tunnel only when the master AC fails.

Examples

# Enable master CAPWAP tunnel preemption for AP ap1.

Predefined user roles

network-admin

Usage guidelines

AP backup enables the active AC (master AC) in an IRF fabric to synchronize information about connected APs to all the non-active ACs. When the active AC fails, one of the non-active ACs becomes active to provide services, ensuring service continuity.

This feature does not take effect on online APs. Disabling this feature removes backup AP information from all ACs.

Examples

# Enable AP backup.

<Sysname> system-view

[Sysname] wlan ap-backup hot-backup enable global

wlan hot-backup keepalive timeout

Use wlan hot-backup keepalive timeout to set the keepalive timeout for AP backup.

Use undo wlan hot-backup keepalive timeout to restore the default.

Syntax

wlan hot-backup keepalive timeout milliseconds

undo wlan hot-backup keepalive timeout

Default

The keepalive timeout is 10000 milliseconds for AP backup.

Views

System view

Predefined user roles

network-admin

Parameters

milliseconds: Specifies the keepalive timeout for AP backup, in the range of 100 to 10000 milliseconds.

Usage guidelines

By default, member ACs use the IRF hello packet mechanism to identify AC status. You can set the keepalive timeout for AP backup as required. Each IRF member AC periodically broadcasts keepalive packets and determines that a member fails If no keepalive packets are received from that member within the keepalive timeout time.

· If the master AC fails, the system will automatically select a new master AC from the subordinate ACs.

· If a subordinate AC fails, the master AC will record the AC failure and transfer services on the subordinate AC to another subordinate AC.

Examples

# Set the keepalive timeout to 2000 milliseconds for AP backup.

<Sysname> system-view

[Sysname] wlan hot-backup keepalive timeout 2000

Client backup commands

display dot1x connection-backup

Parameters

ap ap-name: Specifies an AP by its name, a case-sensitive string of 1 to 64 characters. The string can contain letters, digits, underscores (_), dots (.), left brackets ([), right brackets (]), forward slashes (/), and hyphens (-). If you do not specify an AP, this command displays backup information about all 802.1X clients.

wlan client-backup hot-backup enable

Use wlan client-backup hot-backup enable to enable client backup in an IRF fabric.

Use undo wlan client-backup hot-backup enable to disable client backup in an IRF fabric.

Syntax

wlan client-backup hot-backup enable

undo wlan client-backup hot-backup enable

Default

Client backup is disabled in an IRF fabric.

Views

System view

Predefined user roles

network-admin

Usage guidelines

For this command to take effect, make sure AP backup is enabled.

After client backup is enabled, an active AC backs up information about associated clients to other member ACs. When the active AC fails, the associated clients can associate with another member AC so that the clients are always online.

This command takes effect only on clients that come online after client backup is enabled. Disabling client backup deletes client backup information from all member ACs.

Examples

# Enable client backup.

<Sysname> system-view

[Sysname] wlan client-backup hot-backup enable

wlan client-backup hot-backup delay

Use wlan client-backup hot-backup delay to set the client backup delay.

Use undo wlan client-backup hot-backup delay to restore the default.

Syntax

wlan client-backup hot-backup delay delay-time

undo wlan client-backup hot-backup delay

Default

The client backup delay is 60 seconds.

Views

System view

Predefined user roles

network-admin

Parameters

delay-time: Specifies the client backup delay time in the range of 0 to 300 seconds. If you set the delay time to 0, the AC backs up information changes about associated clients to other ACs in real time.

Parameters

This feature takes effect only when client backup is enabled.

This command takes effect only on clients that come online after the client backup delay is set.

If an active/standby switchover occurs during the delay time, online clients whose information has not been backed up will be logged off and need to come online again. An active/standby switchover can be triggered by a restart of the active AC process.

Examples

# Set the client backup delay to 240 seconds.

<System> system-view

[System] wlan client-backup hot-backup delay 240

WLAN uplink detection commands

wlan uplink track

Use wlan uplink track to associate a track entry with WLAN uplink detection.

Use undo wlan uplink track to restore the default.

Syntax

Default

WLAN uplink detection is not associated with any track entry.

Views

Predefined user roles

network-admin

Parameters

track-entry-number: Specifies a track entry ID in the range of 1 to 1024.

Usage guidelines

This command enables the AC to adjust radio state based on the uplink state associated with a track entry. When the track entry is in Negative state, the AC disables radios of all connected APs. When the track entry is in Positive state, the AC enables radios of all connected APs.

If you execute this command multiple times, the most recent configuration takes effect.

Examples

# Associate track entry 1 with WLAN uplink detection.
