Introduction

The following information provides an example of configuring the local portal service on the AC to send wireless user information to the LDAP server for authentication.

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, portal, and WLAN.

Example: Configuring local portal authentication through the LDAP server

Network configuration

As shown in Figure 1, the AP and the client obtain IP addresses from the DHCP server.

Configuration requirements are as follows:

·     Configure the local portal service on the AC to provide authentication pages for clients.

·     Use the LDAP server to authenticate the clients.

Figure 1 Network diagram

 

Restrictions and guidelines

Configure routing to make sure the devices can reach one another.

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

Edit the authentication pages, compress them to a .zip file (this example uses abc.zip), and then upload the file to the root directory of the storage medium of the AC. On the AC, you must specify this file as the default authentication page file.

To change the default authentication page file, you must first execute the undo default-logon-page command, and then specify a new default authentication page file.

Procedures

Configuring the AC

1.     Configuring VLANs and interfaces:

# Create VLAN 100 and VLAN-interface 100. Assign the VLAN interface an IP address. The AC will use this IP address to establish a CAPWAP tunnel with the AP.

<AC> system-view

[AC] vlan 100

[AC-vlan100] quit

[AC] interface vlan-interface 100

[AC-Vlan-interface100] ip address 2.2.1.1 24

[AC-Vlan-interface100] quit

# Create VLAN 200 and VLAN-interface 200. Assign the VLAN interface an IP address. This VLAN will be used for wireless client access.

[AC] vlan 200

[AC-vlan200] quit

[AC] interface vlan-interface 200

[AC-Vlan-interface200] ip address 2.2.2.1 24

[AC-Vlan-interface200] quit

# Configure GigabitEthernet 1/0/1 (the port connected to the switch) as a trunk port. Assign the port to VLAN 100 and VLAN 200.

[AC] interface gigabitethernet 1/0/1

[AC-GigabitEthernet1/0/1] port link-type trunk

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

[AC-GigabitEthernet1/0/1] quit

2.     Configure the LDAP scheme:

 # Create an LDAP server named ldap and enter its view.

[AC] ldap server ldap

# Specify the administrator DN.

[AC-ldap-server-ldap] login-dn cn=administrator,cn=users,dc=ldap,dc=com

# Specify the base DN for user search.

[AC-ldap-server-ldap] search-base-dn dc=ldap,dc=com

# Specify the IP address of the LDAP server.

[AC-ldap-server-ldap] ip 192.168.0.112

# Specify the administrator password.

[AC-ldap-server-ldap] login-password simple 123456

[AC-ldap-server-ldap] quit

# Create an LDAP scheme named ldap and enter its view.

[AC] ldap scheme ldap

# Specify ldap as the LDAP authentication server.

[AC-ldap-ldap] authentication-server ldap

[AC-ldap-ldap] quit

# Create an ISP domain named ldap and enter its view.

[AC] domain ldap

# Configure the authentication method as LDAP and the authentication and accounting methods as none for portal users in ISP domain ldap.

[AC-isp-ldap]authentication portal ldap-scheme ldap

[AC-isp-ldap] authorization portal none

[AC-isp-ldap] accounting portal none

# Configure the idle cut feature for users in ISP domain ldap. Log out a user if the user's traffic is less than 1024 bytes in 15 minutes.

[AC-isp-ldap] authorization-attribute idle-cut 15 1024

[AC-isp-ldap] quit

3.     Configure portal authentication:

# Create a portal Web server named newpt and specify http://2.2.2.1/portal as the server's URL.

[AC] portal web-server newpt

[AC-portal-websvr-newpt] url http://2.2.2.1/portal

[AC-portal-websvr-newpt] quit

# Create an HTTP-based local portal Web service.

[AC] portal local-web-server http

# Specify file abc.zip as the default authentication page file. (The file must already exist in the root directory of the storage medium of the AC.)

[AC–portal-local-websvr-http] default-logon-page abc.zip

[AC–portal-local-websvr-http] quit

# Configure two destination-based portal-free rules to permit the traffic destined for the DNS server.

[AC] portal free-rule 1 destination ip any udp 53

[AC] portal free-rule 2 destination ip any tcp 53

4.     Configure the wireless service:

# Create a service template named st1 and enter its view.

[AC] wlan service-template st1

# Set the SSID of the service template to service.

[AC-wlan-st-st1] ssid service

# Assign clients coming online through the service template to VLAN 200.

[AC-wlan-st-st1] vlan 200

# Enable direct portal authentication on the service template.

[AC-wlan-st-st1] portal enable method direct

# Specify ISP domain ldap as the portal authentication domain.

[AC-wlan-st-st1] portal domain ldap

# Specify portal Web server newpt on the service template.

[AC-wlan-st-st1] portal apply web-server newpt

# Enable the service template.

[AC-wlan-st-st1] service-template enable

[AC-wlan-st-st1] quit

# Create an AP named officeap with model WA2620E-AGN, and specify the AP model and serial ID.

[AC] wlan ap officeap model WA2620E-AGN

[AC-wlan-ap-officeap] serial-id 21023529G007C000020

# Enter the view of radio 2.

[AC-wlan-ap-officeap] radio 2

# Bind service template st1 to radio 2.

[AC-wlan-ap-officeap-radio-2] service-template st1

[AC-wlan-ap-officeap-radio-2] radio enable

[AC-wlan-ap-officeap-radio-2] quit

[AC-wlan-ap-officeap] quit

Configuring the switch

# Create VLAN 100. The switch will use this VLAN to forward traffic on the CAPWAP tunnel between the AC and AP.

<Switch> system-view

[Switch] vlan 100

[Switch-vlan100] quit

# Create VLAN 200. The switch will use this VLAN to forward traffic of wireless clients.

[Switch] vlan 200

[Switch-vlan200] quit

# Configure GigabitEthernet 1/0/1 (the port connected to the AC) as a trunk port. Assign the trunk port to VLAN 100 and VLAN 200.

[Switch] interface gigabitethernet1/0/1

[Switch-GigabitEthernet1/0/1] port link-type trunk

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

[Switch-GigabitEthernet1/0/1] quit

# Configure GigabitEthernet 1/0/2 (the port connected to the AP) as an access port. Assign the access port to VLAN 100.

[Switch] interface gigabitethernet1/0/2

[Switch-GigabitEthernet1/0/2] port link-type access

[Switch-GigabitEthernet1/0/2] port access vlan 100

# Enable PoE on the access port.

[Switch-GigabitEthernet1/0/2] poe enable

[Switch-GigabitEthernet1/0/2] quit
