Example: Configuring N+1 backup and AP license synchronization

Introduction

This document provides an example for configuring N+1 backup and AP license synchronization in the multi-AC scenario. This configuration helps enhance network reliability and simplify license configuration.

Network configuration

As shown in Figure 1, AP 1 is attached to AC 1 for network access, and AP 2 is attached to AC 2 for network access. Switch 1 acts the DHCP server to assign IP addresses to both the APs and the clients. The network meets the following requirements:

·     N+1 backup is configured. AC 1 and AC 2 act as master ACs, and AC 3 acts as backup AC. When AC 1 or AC 2 fails, AC 3 takes over to provide network access for the APs and the clients.

·     AP licenses are installed on both AC 1 and AC 2. AC 3 share the AP licenses of AC 1 and AC 2. When AC 1 or AC 2 fails, the APs can continue to use the licenses on AC 3.

Figure 1 Network diagram

 

Restrictions and guidelines

·     When you configure N+1 backup, make sure the ACs are of the same AC model. This feature provides backup services for only one failed master AC at a time.

·     N+1 backup is a cold backup method. During a master/backup AC switchover, the APs and clients associated with the failed AC will be disconnected. Network services might take several minutes to recover.

·     Before you configure services, install licenses on each master AC. AP licenses are not shared between master ACs. Only the backup AC share the AP licenses of master ACs.

·     Before you enable AP license synchronization, you must specify IP addresses and roles for the AC and its member ACs in the AP license synchronization group.

·     If one AC is disconnected for more than 30 days, its AP licenses will become invalid on the member AC. Newly connected APs cannot use the shared AP licenses, but online APs will not be disconnected.

·     When you configure the serial number for an AP, make sure the serial number uniquely identifies the AP.

5.     Configure the AP license synchronization feature.

# Configure the management VLAN interface address of AC 2 as the local AC in the AP license synchronization group, configure the management VLAN interface addresses of AC 1 and AC 3 as member ACs, and configure AC 3 as backup.

[AC2-wlan-als-group] ap-license-synchronization enable

[AC2-wlan-als-group] quit

Configuring AC 3

1.     Configure interfaces on AC 3.

# Create VLAN 100 and VLAN-interface 100, and then assign IP address 10.1.1.4/16 to VLAN-interface 100. When AC 1 fails, AP 1 uses the IP address to establish a CAPWAP tunnel with AC 3.

[AC3-GigabitEthernet1/0/1] port trunk permit vlan 100 200

[AC3-GigabitEthernet1/0/1] quit

2.     Configure wireless services and AP settings as you do on AC 1 and AC 2. For more information, see "Configure a wireless service.", "Configure AP settings.", "Configure a wireless service.", and "Configure AP settings.".

3.     Decrease the connection priority of AP 1 and AP 2 for AC 3 to a value lower than that for AC 1 and AC 2. This practice ensures that the APs preferentially connect to AC 1 or AC 2, and turn to AC 3 only if AC 1 or AC 2 fails.

# Create AP group group1, and then set the AP connection priority to 3 for the AC.

[AC3] wlan ap-group group1

[AC3-wlan-ap-group-group1] priority 3

# Create AP group group2, and then set the AP connection priority to 3 for the AC.

[AC3] wlan ap-group group2

[AC3-wlan-ap-group-group2] priority 3

4.     Configure the AP license synchronization feature.

# Configure the management VLAN interface address of AC 3 as the local AC in the AP license synchronization group, configure AC 3 as backup, and configure the management VLAN interface addresses of AC 1 and AC 2 as member ACs.

[AC3] wlan ap-license-group

[AC3-wlan-als-group] local ip 10.1.1.4 backup

[AC3-wlan-als-group] member ip 10.1.1.2

[AC3-wlan-als-group] member ip 10.1.1.3

[AC3-wlan-als-group] ap-license-synchronization enable

[AC3-wlan-als-group] quit

Verifying the configuration

1.     On AC 1, execute the display wlan ap-license-group command to display AP license synchronization group information. An AP license synchronization group has been created, and the number of licenses in the AP license synchronization group equals the sum of licenses installed on AC 1 and AC 2.

<AC1> display wlan ap-license-group

 Group total licenses: 256

 Group used licenses: 1

 AP license synchronization: Enabled

 Local IP: 10.1.1.2

 Local role: Master

 Member information: 2

 10.1.1.4          0          0          Backup            UP         00hr 1min 51sec

2.     On AC 1, execute the display wlan ap all command to verify that AP 1 is in R/M state.

<AC1> display wlan ap all

3.     Shut down VLAN-interface 100 on AC 1, and then verify that AP 1 can access the wireless network via AC 3 after a period. The waiting time depends on the CAPWAP tunnel keepalive timer. The default keepalive timer is 30 seconds. In centralized forwarding mode, master/backup AC switchover will cause traffic interruption.

On AC 3, execute the display wlan ap all command to verify that AP 1 is in R/M state.
