For the dual-link backup feature to function correctly, configure auto AP or manual APs on the two ACs. The manual AP configuration must be identical on both ACs. For more information, see managing APs in AP and WT Management Configuration Guide.

You can configure APs by using the following methods:

· Configure APs one by one in AP view.

· Assign APs to an AP group and configure the AP group in AP group view.

· Configure all APs in global configuration view.

For an AP, the settings made in these views for the same parameter take effect in descending order of AP view, AP group view, and global configuration view.

Dual-link backup tasks at a glance

To configure dual-link backup, perform the following tasks:

1. Setting AP connection priority and specifying a backup AC

2. (Optional.) Configuring master CAPWAP tunnel preemption

Setting AP connection priority and specifying a backup AC

About this task

Set a higher AP connection priority for the master AC to ensure that APs can associate with the master AC first.

After an AP establishes a CAPWAP tunnel with the master AC, the AP will establish a backup CAPWAP tunnel with the specified backup AC.

Procedure

1. Enter system view.

system-view

2. Enter AP view or AP group view.

¡ Enter AP view.

wlan ap ap-name

¡ Enter AP group view.

wlan ap-group group-name

3. Set the AP connection priority.

priority priority

By default:

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

¡ In AP group view, the AP connection priority is 4.

4. Specify a backup AC.

backup-ac { ip ipv4-address | ipv6 ipv6-address }

By default:

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

¡ In AP group view, no backup AC is specified.

Configuring master CAPWAP tunnel preemption

About this task

This feature enables a backup CAPWAP tunnel to become a master tunnel after the specified delay time if the backup AC has higher AP connection priority than the master AC.

Procedure

1. Enter system view.

system-view

2. Enter AP view, AP group view, or global configuration view.

¡ Enter AP view.

wlan ap ap-name

¡ Enter AP group view.

wlan ap-group group-name

¡ Enter global configuration view.

wlan global-configuration

3. Configure master CAPWAP tunnel preemption.

wlan tunnel-preempt { disable | enable }

By 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.

Dual-link backup configuration examples

The AP models and serial numbers in this document are used only as examples. Support for AP models and serial numbers depends on the AC model.

Example: Configuring dual-link backup

Network configuration

As shown in Figure 2, configure AC 1 to act as the master AC and AC 2 as the backup AC. When AC 1 fails and AC 2 takes over, the AP can communicate through AC 2. Configure the master CAPWAP tunnel preemption feature on the two ACs so that the AP reconnects to AC 1 when AC 1 recovers.

Configuring AP backup

About AP backup

AP backup use IRF to enable multiple ACs to form an IRF fabric to ensure centralized AP management and avoid wireless service interruption in case of AC failures.

AC roles

An AC has the following roles:

Role	Description
Master AC	Master in an IRF fabric. A master AC manages the entire IRF fabric.
Subordinate AC	Subordinate in an IRF fabric. A subordinate AC processes services, forwards packets, and acts as a backup for the master AC. When the master AC fails, the system automatically elects a new master AC from the subordinate ACs in the IRF fabric.
Active AC	An AC that can establish CAPWAP tunnels with APs. The master AC is always an active AC.
Non-active AC	An AC that cannot establish CAPWAP tunnels with APs. Non-active ACs can only be subordinate ACs. When an active AC fails, a non-active AC will be elected as an active AC.
Directly connected AC	An AC that receives the first packet from an AP when the AP launches a CAPWAP tunnel establishment process.
Non-directly connected AC	An AC that does not receive the first packet from an AP when the AP launches a CAPWAP tunnel establishment process.

‌

AP backup and recovery

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.

AP backup tasks at a glance

To configure AP backup, perform the following tasks:

1. Enabling AP backup

2. (Optional.) Setting the keepalive timeout for AP backup

Prerequisites for AP backup

Before configuring AP backup, set up an IRF fabric for the target ACs. For information about IRF, see "Configuring an IRF fabric."

Enabling AP backup

About this task

This feature enables the active AC to synchronize information about connected APs to all the non-active ACs. When the active AC fails, one of the non-active AC becomes active to provide services.

Restrictions and guidelines

Disabling this feature removes backup AP information from all ACs.

Procedure

1. Enter system view.

system-view

2. Enable AP backup.

wlan ap-backup hot-backup enable global

By default, AP backup is disabled.

Setting the keepalive timeout for AP backup

About this task

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.

Procedure

1. Enter system view.

system-view

2. Set the keepalive timeout for AP backup.

wlan hot-backup keepalive timeout milliseconds

The default setting is 10000 milliseconds.

Configuring client backup

About client backup

Client backup enables IRF member ACs to backup client information with each other to keep clients online in case of AC failures.

Client backup must work with AP backup. After both features are enabled, active ACs back up connected AP and client information to other member ACs. When an active AC fails, the master AC will select another AC in the IRF fabric to recover information of AP and clients connected to the failed AC. For information about AP backup and AC selection, see "Configuring AP backup."

Configuring WLAN uplink detection

About WLAN uplink detection

When the uplink of an AC fails, clients cannot access external networks through the APs that are connected to the AC. WLAN uplink detection associates the uplink state of an AC with the radio state of the connected APs. When the uplink fails, the AC disables the radios of the APs. When the uplink recovers, the AC enables the radios of the APs. The association ensures that clients can associate with APs connected to another AC when the uplink of an AC fails.

This feature collaborates with a detection module and the Track module to function.

· When the track entry is in Positive state, the AC enables the radios of the connected APs.

· When the track entry is in Negative state, the AC disables the radios of the connected APs.

· When the track entry is in Invalid state, the AC does not change the radio state of the connected APs.

For more information about the track module, see "Configuring Track."

Restrictions and guidelines: WLAN uplink detection

For the WLAN uplink detection feature to function correctly, configure a detection module to detect the uplink state, and associate a track entry with the detection module. For more information, see "Configuring Track."

Configuring WLAN uplink detection

1. Enter system view.

system-view

2. Associate a track entry with the WLAN uplink detection feature.

wlan uplink track track-entry-number

By default, WLAN uplink detection is not associated with any track entry.

WLAN uplink detection configuration examples

Example: Configuring WLAN uplink detection

Network configuration

As shown in Figure 5, use an NQA operation to test the reachability of each AC's uplink. Configure WLAN uplink detection on each AC so that clients can associate with the AP connected to another AC when the uplink of an AC fails.
