How to configure remote authentication for 802.1x authentication users on S series switches

8

802.1x authentication user information (including the user name, password, and other attributes) for remote authentication and authorization is configured on a remote AAA server. Remote authentication and authorization for 802.1x authentication users feature high network security.
For S series and E series switches (except the S1700) running V200R003C10 and earlier versions, NAC can be configured only in common mode. For switches running V200R005C00 and later versions, NAC can be configured in common or unified mode. Accordingly, remote authentication for 802.1x authentication users can be configured in common or unified mode. For switches running V200R009C00, the configuration model of NAC unified mode changes. Query the appropriate product manual based on the switch model and version. The following links are for reference only.

802.1x remote authentication on S series switch
In 802.1x remote authentication and authorization, user information (including the user name, password and attributes) is configured on the remote AAA server. 802.1x remote authentication and authorization feature high network security. S series switches (except S1700 switches) running V200R003C10 or an earlier version supports only traditional NAC configuration. Switches running V200R005C00 or a later version support both traditional and unified NAC configuration. By default, unified NAC configuration is used. 802.1x remote authentication also supports traditional and unified modes. 802.1x remote authentication configuration is the same on all switch models: - For the traditional 802.1x remote authentication configuration, see "Example for Configuring 802.1x Authentication to Control Internal User Access" in "Configuring NAC (Common Mode)" of Typical Configuration Examples. - For the unified 802.1x remote authentication configuration, see "Example for Configuring 802.1x Authentication to Control Internal User Access" in "Configuring NAC (Unified Mode)" of Typical Configuration Examples.

How to configure local authentication for 802.1x authentication users on S series switches
For S series switches (except the S1700), 802.1x authentication user information (including the user name, password, and other attributes of a local user) for local authentication and authorization is configured on the switches. Local authentication and authorization for 802.1x authentication users feature fast processing and low operation cost, but the amount of information that can be stored is limited by the switch hardware capacity.
Assume that a user connects to GE0/0/1 on a switch and belongs to VLAN 100. After local authentication is configured for the user on the switch, the user can access the network without being authorized. Configure local authentication for an 802.1x authentication user as follows:
1. Create VLAN 100 and add GE0/0/1 to the VLAN.
[HUAWEI] vlan batch 100 
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1] port link-type access
[HUAWEI-GigabitEthernet0/0/1] port default vlan 100 
[HUAWEI-GigabitEthernet0/0/1] quit
2. Create a local user and an authentication domain for the local user.
[HUAWEI] aaa     
[HUAWEI-aaa] local-user huawei password cipher hello@123
[HUAWEI-aaa] local-user huawei service-type 8021x
[HUAWEI-aaa] authentication-scheme test
[HUAWEI-aaa-authen-test] authentication-mode local
[HUAWEI-aaa-authen-test] quit
[HUAWEI-aaa] authorization-scheme test
[HUAWEI-aaa-author-test] authorization-mode none
[HUAWEI-aaa-author-test] quit
[HUAWEI-aaa] domain default_admin
[HUAWEI-aaa-domain-default_admin] authentication-scheme test
[HUAWEI-aaa-domain-default_admin] authorization-scheme test
3. Enable 802.1x authentication in the system view and on a specified interface.
a. In common mode (applicable to switches running all versions):
[HUAWEI] undo authentication unified-mode  //Change the NAC mode to common. This step is required only on switches running V200R005C00 and later versions.br>[HUAWEI] quit
<HUAWEI> reboot   //This step is required only on switches running V200R005C00 and later versions.

[HUAWEI] interface gigabitethernet0/0/1
[HUAWEI-GigabitEthernet0/0/1] dot1x enable
[HUAWEI-GigabitEthernet0/0/1] dot1x authentication-method eap
b. In unified mode (applicable to switches running versions from V200R005 to V200R008):
[HUAWEI] authentication unified-mode 
[HUAWEI] interface gigabitethernet0/0/1
[HUAWEI-GigabitEthernet0/0/1] authentication dot1x
[HUAWEI-GigabitEthernet0/0/1] authentication mode multi-authen max-user 100
c. In unified mode (applicable to switches running V200R009 and later versions):

How to configure remote 802.1x authentication
In remote authentication and authorization, user information including the user name, password, and attributes is configured on the remote AAA server. This mode has high network security. An example is used here to describe remote 802.1x authentication. Assume that a user connects to GE1/0/0 on an AR and belongs to VLAN 10. GE1/0/2 connects to the RADIUS server and belongs to VLAN 20. RADIUS authentication and non-accounting are used for the user, and the IP address of the RADIUS server is 192.168.2.30:1812. 1. Configure interfaces and VLANs so that the AR can communicate with the RADIUS server. [Huawei] vlan batch 10 20 [Huawei] interface gigabitethernet 1/0/1 [Huawei-GigabitEthernet1/0/1] port link-type access [Huawei-GigabitEthernet1/0/1] port default vlan 10 [Huawei-GigabitEthernet1/0/1] quit [Huawei] interface gigabitethernet 1/0/2 [Huawei-GigabitEthernet1/0/2] port link-type access [Huawei-GigabitEthernet1/0/2] port default vlan 20 [Huawei-GigabitEthernet1/0/2] quit 2. Configure a RADIUS server template, a domain, and AAA schemes. [Huawei] radius-server template rd1 [Huawei-radius-rd1] radius-server authentication 192.168.2.30 1812 [Huawei-radius-rd1] radius-server shared-key cipher Huawei@2012 [Huawei-radius-rd1] quit [Huawei] aaa [Huawei-aaa] authentication-scheme abc [Huawei-aaa-authen-abc] authentication-mode radius [Huawei-aaa-authen-abc] quit [Huawei-aaa] domain isp1 [Huawei-aaa-domain-isp1] authentication-scheme abc [Huawei-aaa-domain-isp1] radius-server rd1 [Huawei-aaa-domain-isp1] quit [Huawei-aaa] quit 3.

802.1x local authentication configuration on S series switch
For S series switches except S1700 switches, in 802.1x local authentication and authorization, user information (including the local user name, password, and attributes) is configured on the switch. 802.1x local authentication and authorization feature fast processing and low operation cost, whereas the amount of information that can be stored is limited by the switch hardware capacity.
Assume that the user connects to GE0/0/1 of the switch and belongs to VLAN 100. In addition, the user uses local authentication and can connect to the network without authorization. Configure 802.1x local authentication as follows:
1. Create VLAN 100, and add interface GE0/0/1 to this VLAN.
[HUAWEI] vlan 100 
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1] port link-type access
[HUAWEI-GigabitEthernet0/0/1] port default vlan 100 
[HUAWEI-GigabitEthernet0/0/1] quit
2. Configure the local user and the authentication domain of the user.
[HUAWEI] aaa     
[HUAWEI-aaa] local-user huawei password cipher hello@123
[HUAWEI-aaa] local-user huawei service-type 8021x
[HUAWEI-aaa] authentication-scheme test
[HUAWEI-aaa-authen-test] authentication-mode local
[HUAWEI-aaa-authen-test] quit
