WLAN high availability commands
Dual-link backup commands
backup-ac
Use backup-ac to specify a backup AC.
Use undo backup-ac to remove the backup AC configuration.
Syntax
backup-ac { ip ipv4-address | ipv6 ipv6-address }
undo backup-ac { ip | ipv6 }
Default
In AP view, an AP uses the configuration in AP group view.
In AP group view, no backup AC is specified.
Views
AP view
AP group view
Predefined user roles
network-admin
Parameters
ip ip-address: Specifies a backup AC by its IPv4 address.
ipv6 ipv6-address: Specifies a backup AC by its IPv6 address.
Usage guidelines
You can specify only one IPv4 address or one IPv6 address in either AP view or AP group view.
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 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.
<Sysname> system-view
[Sysname] wlan ap ap1 model WA6320
[Sysname-ap-ap1] wlan tunnel-preempt enable
# Enable master CAPWAP tunnel preemption for APs in AP group group1.
<Sysname> system-view
[Sysname] wlan ap-group group1
[Sysname-wlan-ap-group-group1] wlan tunnel-preempt enable
# Enable master CAPWAP tunnel preemption globally.
<Sysname> system-view
[Sysname] wlan global-configuration
[Sysname-wlan-global-configuration] wlan tunnel-preempt enable
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
wlan uplink track track-entry-number
undo wlan uplink track
Default
WLAN uplink detection is not associated with any track entry.
Views
System view
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.
<Sysname> system-view
[Sysname] wlan uplink track 1
