Introduction

The following information provides an example of configuring remote portal authentication for clients on an AC hierarchy network where two central ACs are deployed for redundancy.

Prerequisites

The following information applies to Comware 7-based access controllers and access points. Procedures and information in the examples might be slightly different depending on the software or hardware version of the access controllers and access points.

The configuration examples were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

The following information is provided based on the assumption that you have basic knowledge of AAA, WLAN user authentication, WLAN access, and WLAN high availability.

Example: Configuring remote portal authentication on an AC hierarchy network with dual-link central AC backup

Network configuration

As shown in Figure 1, the AC hierarchy network contains two central ACs WX5560H, one local AC WX3510H, and one AP WA5320H. The AP and client obtain an IP address from the DHCP server, and the IMC server acts as both the portal authentication server and RADIUS server. Configure the devices to meet the following requirements:

·     The central ACs operate in master/backup mode and back up each other.

·     The master central AC has all licenses registered, and it can synchronize the licenses to the backup central AC by using the AP license synchronization feature.

·     The AC rediscovery feature is configured on the central ACs. For the AP to associate with the local AC, enable the AC rediscovery feature in the view of the manual AP. In addition, configure the central ACs to add the IP address of the local AC to the CAPWAP Control IP Address message element in the discovery responses sent to the AP. The AP, central ACs, and the local AC are reachable to each other so that the AP can associate with a central AC when the local AC fails.

·     Use direct portal authentication for wireless clients.

Figure 1 Network diagram

 

Analysis

·     For GigabitEthernet 1/0/1 to forward client data traffic in VLAN 200, edit the configuration file of the AP and upload the file to the central ACs.

·     For portal users that have been authenticated on an AC to roam to another AC to access the network resources without re-authentication, enable roaming for portal users.

·     To avoid portal authentication failure caused by frequent portal client onboarding and offboarding, disable the Rule ARP entry feature for portal clients.

·     For the RADIUS server to dynamically change client authorization information or forcibly disconnect a wireless client, enable the RADIUS session-control feature on the central ACs.

Software version used

This example was created and verified on Release 5426.

Restrictions and guidelines

·     Make sure the settings are the same on the primary and backup central ACs.

·     Make sure the software versions are the same for the primary and backup central ACs.

·     Central ACs on an AC hierarchy network do not support IRF.

·     Use the serial ID labeled on the AP's rear panel to specify an AP.

·     On the local AC, do not enable the auto AP feature. In addition, create a manual AP for the AP in local AC view on the central ACs for the central ACs to manage the AP.

·     For dual-link central AC backup to operate correctly, configure the local AC and manual AP settings on both central ACs. Make sure the priority settings on the local AC, the master central AC, and the backup central AC are correctly configured so that the local AC can re-associate with the master central AC when the master central AC recovers.

Configuring the RADIUS server

In this example, the RADIUS server runs IMC PLAT 7.1 (E0303p13), IMC EIA 7.1 (F0302p08), and IMC EIP 7.1 (F0302p08).

1.     Add an access device.

a.     Log in to IMC and click the User tab.

b.     From the navigation pane, select User Access Policy > Access Device Management > Access Device.

c.     Click Add.

d.     In the Device List area, click Add Manually to open the Add Access Device Manually page. Enter 2.2.2.1 in the Start IP field and then click OK.

e.     In the Access Configuration area, set the shared key to radius, which must be the same as that configured on the AC.

f.     Use the default settings for other parameters.

g.     Click OK.

Figure 2 Adding an access device

 

2.     Add an access policy.

a.     From the navigation pane, select User Access Policy > Access Policy.

b.     Click Add.

c.     Enter the access policy name.

d.     Select the Ungrouped service group.

e.     Use the default settings for other parameters.

2.     Configure an IP address group:

a.     From the navigation pane, select User Access Policy > Portal Service > IP Group.

b.     Click Add.

c.     Enter the IP group name.

d.     Enter the start IP address and end IP address of the IP group.

Make sure the client IP address is in the IP group.

e.     Select a service group.

This example uses the default group Ungrouped.

f.     Select Normal from the Action list.

g.     Click OK.

Figure 7 Adding an IP address group

 

3.     Add a portal device:

a.     From the navigation pane, select User Access Policy > Portal Service > Device.

b.     Click Add.

4.     Associate the portal device with the IP address group:

a.     Click the Port Group icon in the Operation field of device NAS.

Figure 9 Device list

 

b.     Click Add.

c.     Enter the port group name.

d.     Select the configured IP address group.

The IP address used by the user to access the network must be within this IP address group.

e.     Use the default settings for other parameters.

f.     Click OK.

Verifying the configuration

# Use the configured username and password to perform portal authentication through a Web browser on the client. Before passing portal authentication, the user can access only the authentication page http://192.168.0.111:8080/portal. All Web requests from the user will be redirected to the authentication page. After passing portal authentication, the user can access other network resources.
