With dual-link backup enabled, an AP establishes a master CAPWAP tunnel and a backup CAPWAP tunnel with the master AC and the backup AC, respectively. The master and backup ACs cannot detect each other's link state in real time. When the backup AC takes over traffic forwarding upon a master AC failure, temporary communication interruption occurs. When the failed master AC recovers, the master CAPWAP tunnel preemption feature determines the master CAPWAP tunnel based on the AP connection priority.

Dual-link backup is applicable to networks that are service continuity insensitive.

Figure 1 Network diagram for dual-link backup

‌

Restrictions and guidelines: Dual-link backup configuration

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."

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

3. (Optional.) Enabling client persistence

4. (Optional.) Configuring configuration synchronization between ACs in a dual-link backup system

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 a 10-minute delay 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.

Enabling client persistence

About this task

In a dual-link network, when the backup AC becomes the master AC, it synchronizes all client entries with the master AC. During the synchronization, wireless clients will go offline simultaneously and it will take a long time for them to come online again. With this feature enabled, the backup AC synchronizes entries with the master AC slowly, allowing wireless clients to slowly go offline and come online, thereby keeping clients online. This function is supported only when the client data packet forwarding location is on the AP.

To use this feature together with portal authentication, configure MAC-based quick portal authentication for users to complete authentication without awareness.

During master/backup switchover, the backup AC uses temporary client data to ensure that clients do not disconnect. After the switchover, you must execute wlan persistent-client reconnect on the new master AC to log off clients in batches and delete their temporary data. After the clients come online again, the new master AC regenerates normal client data.

Procedure

1. Enter system view.

system-view

2. Enter global configuration view.

wlan global-configuration

3. Enable client persistence.

client-persistence enable

By default, client persistence is disabled.

4. (Optional.) Configure delayed client reconnection for client persistence.

Configuring configuration synchronization between ACs in a dual-link backup system

Configuring synchronizing WLAN configuration between ACs in a dual-link backup system

About this task

As a best practice to ensure configuration consistency between the two ACs in a dual-link backup system, configure WLAN settings on the AC with the TM role and then use this function to synchronize the WLAN settings to the AC with the TC role.

WLAN settings includes settings in AP view, AP group view, global configuration view, radio view, an AP group's radio view, and service template view, as well as settings related to authentication.

The following conditions might occur if you enable this feature:

· When the two ACs have the same WLAN settings, WLAN configuration synchronization is not performed.

· When the two ACs have different WLAN settings, the system generates a diff file named wlan_cfgsync.diff on the AC with the TM role and then automatically performs configuration synchronization. To view the WLAN configuration differences between the two ACs, use the more command.

Restrictions and guidelines

To use this feature, first set up a SmartMC network. This feature is supported only on the AC with the TM role.

Procedures

1. Enter system view.

system-view

2. Configure synchronizing WLAN configuration between ACs in a dual-link backup system.

wlan sync-configuration { from | to } peer-ac mac-address

Triggering consistency check on the WLAN configuration between the two ACs in a dual-link backup system

About this task

Perform this task to verify if the WLAN settings on the two ACs in a dual-link backup system are consistent. If an inconsistency is found, the AC with the TM role generates a diff file named wlan_cfgsync.diff. You can use the more command to view the diff file and determine whether to perform WLAN configuration synchronization and the synchronization direction.

Restrictions and guidelines

To use this feature, first set up a SmartMC network. This feature is supported only on the AC with the TM role.

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 High Availability Configuration Guide.

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 track configuration in High Availability Configuration Guide.

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 3, 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.
