- Web认证(内部半径)
- Web转接
Prerequisites
Requirements
Cisco推荐您有这些题目基础知识：
- 802.1x
- PSK
- RADIUS
- Web 身份验证
Components Used
本文的信息根据AP 3700版本15.3(3)JBB。
The information in this document was created from the devices in a specific lab environment.All of the devices used in this document started with a cleared (default) configuration.如果您的网络处于活动状态，请确保您了解所有命令的潜在影响。
提示： 这些示例在自动模式下也适用于AP在ASA 5506里面，区别是那而不是配置交换端口AP被连接的地方，配置适用于ASA的Gig 1/9。
Configure
Note: 属于同样VLAN的服务集标识(Ssid)不可能同时被应用于无线电。 Ssid的配置示例与同样VLAN的在同样AP同时未被启用。
配置Vlan-switch和AP
配置在AP的必需的VLAN并且交换。这些是用于此示例的VLAN ：
- VLAN 2401 (本地)
- VLAN 2402
- VLAN 2403
配置APs和VLAN
配置接口千兆以太网
# conf t # interface gig 0.2401 # encapsulation dot1q 2401 native # interface gig 0.2402 # encapsulation dot1q 2402 # bridge-group 242 # interface gig 0.2403 # encapsulation dot1q 2403 # bridge-group 243
配置接口无线电802.11a
# interface dot11radio 1.2401 # encapsulation dot1q 2401 native # interface dot11radio 1.2402 # encapsulation dot1q 2402 # bridge-group 242 # interface dot11radio 1.2403 # encapsulation dot1q 2403 # bridge-group 243
Note: 没有配置802.11b无线电(接口dot11radio 0)，因为使用AP的本地VLAN。
配置交换机VLAN
# conf t # vlan 2401-2403
配置接口AP被连接的地方：
# conf t # interface <port-id-where-AP-is-connected> # switchport trunk encapsulation dot1q # switchport mode trunk # switchport trunk native vlan 2401 # switchport trunk allowed vlan 2401-2403 # spanning-tree portfast trunk
SSID开放式验证- AP的本地VLAN
此SSID没有安全，加入WLAN播放的(可视对客户端)，并且无线客户端被分配到本地VLAN。
步骤1.配置SSID。
# dot11 ssid OPEN # authentication open # guest-mode
步骤2.分配SSID到802.11b无线电。
# interface dot11radio 0 # ssid OPEN
SSID 802.1x -内部RADIUS
此SSID使用AP作为RADIUS服务器。注意AP， RADIUS服务器只支持LEAP、EAP-FAST和MAC验证。
步骤1. Enable (event) AP作为RADIUS服务器。
网络访问Server(NAS) IP地址是AP的BVI，因为此IP地址是发送认证请求到本身的那个。并且，请创建一个用户名和密码。
# aaa new-model # radius-server local # nas <a.b.c.d> key 0 <shared-key> # user <username> password 0 <password>
步骤2.配置AP发送认证请求的RADIUS服务器，因为它是本地RADIUS， IP地址是那个分配到AP的网桥Vitrual接口(BVI)。
# radius server <radius-server-name> # address ipv4 <a.b.c.d> auth-port 1812 acct-port 1813 # timeout 10 # retransmit 3 # key 0 <shared-key>
步骤3.分配此RADIUS服务器到半径组。
# aaa group server radius <radius-group> # server name <radius-server-name>
步骤4.分配此半径组到认证方法。
# aaa authentication login <eap-method-name> group <radius-group>
步骤5.创建SSID，分配它到VLAN 2402。
# dot11 ssid internal-radius # vlan 2402 # authentication open eap <eap-method-name> # authentication network-eap <eap-method-name> # authentication key-management wpa version 2 # mbssid guest-mode
步骤6.分配ssid到接口802.11a并且指定密码模式。
# interface dot11radio 1 # mbssid # encryption vlan 2402 mode ciphers aes-ccm # ssid internal-radius
SSID 802.1x -外部RADIUS
配置几乎是相同的象内部RADIUS。
步骤1.配置aaa new-model。
而不是AP的IP地址的第2步，使用外部RADIUS IP地址。
SSID - PSK
此SSID使用此SSID的安全WPA2/PSK和用户分配到VLAN 2402。
步骤1.配置SSID。
# conf t # dot11 ssid PSK-ex # authentication open # authentication key-management wpa version 2 # wpa-psk ascii 0 <password> # mbssid guest-mode # vlan 2402
步骤2.分配SSID到无线接口并且配置密码模式。
# interface dot11radio 1 # encryption vlan 2402 mode ciphers aes-ccm # ssid PSK-ex
SSID - MAC地址验证
此SSID验证根据他们的MAC地址的无线客户端。它使用MAC地址作为用户名/密码。在本例中AP作为本地RADIUS，因此AP存储MAC地址列表。相同配置可以用外部RADIUS服务器运用。
步骤1. Enable (event) AP作为RADIUS服务器。NAS IP地址是AP的BVI。用MAC地址aaaabbbbcccc创建客户端的条目。
# aaa new-model # radius-server local # nas <a.b.c.d> key 0 <shared-key> # user aaaabbbbcccc password 0 aaaabbbbcccc mac-auth-only
步骤2.配置AP发送认证请求的RADIUS服务器(它是AP)。
# radius server <radius-server-name> # address ipv4 <a.b.c.d> auth-port 1812 acct-port 1813 # timeout 10 # retransmit 3 # key 0 <shared-key>
步骤3.分配此RADIUS服务器到半径组。
# aaa group server radius <radius-group> # server name <radius-server-name>
步骤4.分配此半径组到认证方法。
# aaa authentication login <mac-method> group <radius-group>
步骤5.创建SSID，此示例分配它到VLAN 2402。
# dot11 ssid mac-auth # vlan 2402 # authentication open mac-address <mac-method> # mbssid guest-mode
步骤6.分配SSID到接口802.11a。
# interface dot11radio 1 # mbssid # ssid mac-auth
SSID -内部Web认证
连接到此SSID的用户重定向到Web认证门户输入有效用户名/密码，如果认证是成功的，他们访问网络。在本例中，用户在本地RADIUS服务器存储。
在本例中， SSID分配到VLAN 2403。
步骤1. Enable (event) AP作为RADIUS服务器。NAS IP地址是AP的BVI。
# aaa new-model # radius-server local # nas <a.b.c.d> key 0 <shared-key>
步骤2.配置AP发送认证请求的RADIUS服务器(它是AP)。
# radius server <radius-name> # address ipv4 <a.b.c.d> auth-port 1812 acct-port 1813 # timeout 10 # retransmit 3 # key 0 <shared-key>
步骤3.分配此RADIUS服务器到半径组。
# aaa group server radius <radius-group> # server name <radius-name>
步骤4.分配此半径组到认证方法。
# aaa authentication login <web-method> group <radius-group>
步骤5.创建准入策略。
# ip admission name webauth-pol proxy http # ip admission name webauth-pol method-list authentication <web-method>
步骤6.配置SSID。
# conf t # dot11 ssid webauth-autonomous # authentication open # web-auth # vlan 2403 # mbssid guest-mode
步骤7.分配SSID到接口。
# conf t # int dot11radio 1 # ssid webauth-autonomous
步骤8.分配策略到正确的sub-interface。
# conf t # int dot11radio 1.2403 # ip admission webauth-pol
Note: 如果SSID在本地工作，则策略被运用直接地于接口，不于sub-interface (dot11radio 0或dot11radio 1)。
步骤9.创建客人身份的用户的用户名/密码。
# conf t # dot11 guest # username <username> lifetime 35000 password <password>
SSID -Web转接
当客户端连接到SSID用Web转接配置，将重定向到Web门户接受条件&网络使用的条件，如果没有，用户不能使用服务。
此示例分配SSID到本地VLAN。
步骤1.创建准入策略。
# config t # ip admission name web-passth consent
步骤2.，当客户端连接到此SSID时，请指定将显示的消息。
# ip admission consent-banner text %
======= WELCOME ======
Message to be displayed to clients
.........
.........
.........
.........
.........
%
步骤3.创建SSID。
# dot11 ssid webpassth-autonomous # web-auth # authentication open # guest-mode
步骤4.分配SSID和准入策略到无线电
# interface dot11radio { 0 | 1 }
# ssid webpassth-autonomous
# ip admission web-passth
Verify
