任务一 无线网络的基本配置

      信科公司的WLAN集群管理采用AC+FitAP的模式。在AC上面可以对AP进行基本的配置管理操作,包括向Valided AP表中添加AP、配置AP的位置信息。本任务介绍了在AC上配置AP的具体操作,网络拓扑图如图4-1所示。 

 图4-2  网络拓扑图

步骤1   安装无线路由器和无线AP,连接方式如下网络拓扑图

进行终端登录,Windows XP可以使用系统自带的管理终端进行登录,Windows 7可下载软件“SecureCRT”进行登录。登录前在“快速连接”对话框中设置软件参数并点击“连接”,如图4-3所示。 

 

步骤2  在AC上面对与之关联的AP进行配置。配置AP的位置信息为“cn”,代码如下: 

sys /*进入系统视图/ wlan /*进入到wlan视图下/ regulatory-domain-profile name domain1 /*创建域管理的模板,名称为domain1/ country-code cn /*国家编码为cn(中国)/ quit /*返回到wlan视图下/ ap-group name apg-lhh /*创建ap管理组,组名为apg-lhh/ regulatory-domain-profile domain1 /*将域管理模板引入到apg-lhh组里/ /返回系统视图下/ wlan /*进入到wlan视图下/ ap auth-mode mac-auth /*ap的认证方式为mac认证/ ap-id 1 ap-mac 00e0-fcc6-2a10 /*ap序号为1,mac地址为00e0-fcc6-2a10 / ap-name ap-wifi1 /*将此ap命名为ap-wifi1 / ap-group apg-lhh /*将此ap放入到apg-lhh组里/ /返回系统视图下/

任务二  无线网络的接入 

        信科公司部署无线网络之后,陆续因无线接入出现网络故障,影响了网络的稳定。经过分析研究,公司决定把办公无线接入和来宾接入隔离,使用两个SSID标识,负载均衡,提高网络安全,网络拓扑图如图4-4所示。具体操作如下: 

图4-4  网络拓扑图 

注:云端开启步骤:

(1)双击“云朵”,使用端口选项选择GE

(2)端口映射设置

 

步骤1 配置出口路由器/核心交换机/AC的IP地址、端口 

(1)配置出口路由器端口 

 

sys Enter system view, return user view with Ctrl+Z. [Huawei]sysname AR [AR]int g0/0/0 [AR-GigabitEthernet0/0/0]ip add 10.0.0.2 24 Oct 4 2022 19:50:58-08:00 AR %%01IFNET/4/LINK_STATE(l)[0]:The line protocol IP on the interface GigabitEthernet0/0/0 has entered the UP state. [AR-GigabitEthernet0/0/0]q [AR]

 (2)配置AC

sys Enter system view, return user view with Ctrl+Z. [AC6005]sysname AC1 [AC1]vlan ba [AC1]vlan batch 10 Info: This operation may take a few seconds. Please wait for a moment...done. [AC1]int vlan [AC1]int Vlanif 10 [AC1-Vlanif10]ip add 172.16.1.2 24 # 与核心交换机直连的IP地址 [AC1-Vlanif10]int g0/0/1 [AC1-GigabitEthernet0/0/1]port link-type trunk [AC1-GigabitEthernet0/0/1]port trunk allow-pass vlan all [AC1-GigabitEthernet0/0/1]q [AC1]

(3) 配置核心交换机

sys [Huawei]sysname LSW1 [LSW1]vlan batch 5 10 [LSW1]int vlanif 1 [LSW1-Vlanif1]ip add 10.0.0.1 24 [LSW1-Vlanif1]int vlanif 5 [LSW1-Vlanif5]ip add 192.168.0.1 24 [LSW1-Vlanif5]int vlanif 10 [LSW1-Vlanif10]ip add 172.16.1.1 24 [LSW1-Vlanif10]int g0/0/4 [LSW1-GigabitEthernet0/0/4]port link-type trunk [LSW1-GigabitEthernet0/0/4]port trunk allow-pass vlan all

 步骤2 配置AC/出口路由器的路由,使其能相互通信。

 (1)首先AC设置静态路由

sys Enter system view, return user view with Ctrl+Z. [AC1]ip route-static 0.0.0.0 0 172.16.1.1 [AC1]

(2)其次 路由器设置静态路由 

sys Enter system view, return user view with Ctrl+Z. [AR]ip route-static 0.0.0.0 0 10.0.0.1 [AR]

 (3)最后 在AC上测试连通性

## 在AC上ping一下路由器,测试网络是否联通: ping 10.0.0.2 PING 10.0.0.2: 56 data bytes, press CTRL_C to break Reply from 10.0.0.2: bytes=56 Sequence=1 ttl=254 time=60 ms Reply from 10.0.0.2: bytes=56 Sequence=2 ttl=254 time=30 ms Reply from 10.0.0.2: bytes=56 Sequence=3 ttl=254 time=40 ms Reply from 10.0.0.2: bytes=56 Sequence=4 ttl=254 time=40 ms Reply from 10.0.0.2: bytes=56 Sequence=5 ttl=254 time=50 ms ## 确认无误再进行下一步 步骤3 配置核心交换机DHCP,使其能分配IP地址给AP

## 配置与AP相连的端口 sys [LSW1]port-group group-member g0/0/1 to g0/0/3 # 端口组 [LSW1-port-group]port link-type trunk [LSW1-port-group]port trunk allow-pass vlan all [LSW1-port-group]port trunk pvid vlan 5 [LSW1-port-group]quit

## 配置DHCP地址池 [LSW1]dhcp enable # 使能DHCP [LSW1]ip pool vlan5 # 创建地址池 [LSW1-ip-pool-vlan5]network 192.168.0.0 mask 24 # 配置要分配的网段 [LSW1-ip-pool-vlan5]gateway-list 192.168.0.1 # 配置要分配的网关地址 [LSW1-ip-pool-vlan5]option 43 sub-option 3 ascii 172.16.1.2 # 将AC的IP地址下发给AP [LSW1-ip-pool-vlan5]quit [LSW1]int vlanif 5 [LSW1-Vlanif5]dhcp select global #在接口上下发IP地址

 

 查看AP的地址有没有上来;以AP1为例,双击AP设备,输入以下代码:

dis ip int bri

 ping一下AC看看通不通

ping 172.16.1.2 PING 172.16.1.2: 56 data bytes, press CTRL_C to break Reply from 172.16.1.2: bytes=56 Sequence=1 ttl=254 time=30 ms Reply from 172.16.1.2: bytes=56 Sequence=2 ttl=254 time=30 ms Reply from 172.16.1.2: bytes=56 Sequence=3 ttl=254 time=20 ms Reply from 172.16.1.2: bytes=56 Sequence=4 ttl=254 time=40 ms Reply from 172.16.1.2: bytes=56 Sequence=5 ttl=254 time=30 ms --- 172.16.1.2 ping statistics --- 5 packet(s) transmitted 5 packet(s) received 0.00% packet loss round-trip min/avg/max = 20/30/40 ms

 确认无误,进行下一步

步骤4   注册AP

注:以下配置,可能会弹出的警告,都选Y。

sys Enter system view, return user view with Ctrl+Z. #指定capwap协议的信令源地址 [AC1]capwap source interface Vlanif 10 [AC1]wlan # 进入wlan视图 [AC1-wlan-view]ap auth-mode mac-auth # 配置AC的验证方式为MAC验证 ## 创建域配置并配置国家码,使AP的射频特性符合国家的法律法规要求 [AC1-wlan-view]regulatory-domain-profile name CN # 创建域配置 [AC1-wlan-regulate-domain-CN]country-code CN # 国家码:中国 Info: The current country code is same with the input country code. [AC1-wlan-regulate-domain-CN]q ## 创建AP-group [AC1-wlan-view]ap-group name guest # 创建guest组 [AC1-wlan-ap-group-guest]regulatory-domain-profile CN # 关联刚才的域配置 Warning: Modifying the country code will clear channel, power and antenna gain c onfigurations of the radio and reset the AP. Continue?[Y/N]:y [AC1-wlan-ap-group-guest]q [AC1-wlan-view]ap-group name work # 创建work组 Info: This operation may take a few seconds. Please wait for a moment.done. [AC1-wlan-ap-group-work]regulatory-domain-profile CN # 关联刚才的域配置 Warning: Modifying the country code will clear channel, power and antenna gain c onfigurations of the radio and reset the AP. Continue?[Y/N]:y [AC1-wlan-ap-group-work]q

 查看AP的MAC地址如下:

(1)依次双击AP1,AP2,AP3,输入指令:

 

将mac地址复制备用:

AP1:00e0-fc54-49d0 

 AP2:  00e0-fc4d-4a80 

AP3: 00e0-fc15-5570

## 基于mac地址注册AP sys Enter system view, return user view with Ctrl+Z. [AC1]wlan [AC1-wlan-view]ap-id 1 ap-mac 00e0-fc54-49d0 # 加入AP。mac地址可以通过查看核心交换机的mac地址表,或者右键AP打开设置查看 [AC1-wlan-ap-1]ap-name guest1 # 将AP名字更改为guest1 [AC1-wlan-ap-1]ap-group guest # 将AP加入刚才配置的guest组 Warning: This operation may cause AP reset. If the country code changes, it will clear channel, power and antenna gain configurations of the radio, Whether to c ontinue? [Y/N]:y Info: This operation may take a few seconds. Please wait for a moment.. done. [AC1-wlan-ap-1]q [AC1-wlan-view]ap-id 2 ap-mac 00e0-fc4d-4a80 [AC1-wlan-ap-2]ap-name guest2 [AC1-wlan-ap-2]ap-group guest Warning: This operation may cause AP reset. If the country code changes, it will clear channel, power and antenna gain configurations of the radio, Whether to c ontinue? [Y/N]:y Info: This operation may take a few seconds. Please wait for a moment.. done. [AC1-wlan-ap-2]q [AC1-wlan-view]ap-id 3 ap-mac 00e0-fc15-5570 [AC1-wlan-ap-3]ap-name work1 [AC1-wlan-ap-3]ap-group work Warning: This operation may cause AP reset. If the country code changes, it will clear channel, power and antenna gain configurations of the radio, Whether to c ontinue? [Y/N]:y Info: This operation may take a few seconds. Please wait for a moment.. done. [AC1-wlan-ap-3]q [AC1-wlan-view]

 注: 到此处AP会自动重启,且AP名字会被更改(如果没有自动重启,可以自己手动重启) ; 重启完在AC上查看AP是否注册成功: 

sys Enter system view, return user view with Ctrl+Z. [AC1]wlan [AC1-wlan-view]dis ap all Info: This operation may take a few seconds. Please wait for a moment.done. Total AP information: nor : normal [3] -------------------------------------------------------------------------------- ---------- ID MAC Name Group IP Type State STA Uptime -------------------------------------------------------------------------------- ---------- 1 00e0-fc54-49d0 guest1 guest 192.168.0.254 AP2050DN nor 0 9M:21S 2 00e0-fc4d-4a80 guest2 guest 192.168.0.253 AP2050DN nor 0 8M:15S 3 00e0-fc15-5570 work1 work 192.168.0.252 AP2050DN nor 0 7M:14S -------------------------------------------------------------------------------- ---------- Total: 3 [AC1-wlan-view]

 ​​​​​​

 可以看到state为nor,说明注册成功;

等三台设备全部上线,确认无误再进行下一步

步骤5 分配无线参数 [AC1]vlan pool sta-pool101 # 新建vlan地址池,名称为sta-pool101 [AC1-vlan-pool-sta-pool101]vlan 101 [AC1-vlan-pool-sta-pool101]quit [AC1]vlan pool sta-pool102 [AC1-vlan-pool-sta-pool102]vlan 102 [AC1-vlan-pool-sta-pool102]quit ## 安全配置(WIFI密码) [AC1]wlan [AC1-wlan-view]security-profile name guest # 新建安全配置,名称为guest [AC1-wlan-sec-prof-guest]security wpa2 psk pass-phrase a12345678 aes # 配置加密方式为wpa2-psk,aes密文存放 [AC1-wlan-sec-prof-guest]quit [AC1-wlan-view]security-profile name work [AC1-wlan-sec-prof-work]security wpa2 psk pass-phrase a12345678 aes [AC1-wlan-sec-prof-work]quit ## SSID配置(WIFI名称) [AC1-wlan-view]ssid-profile name guest # 新建SSID配置,名称为guest [AC1-wlan-ssid-prof-guest]ssid guest # 配置SSID名为guest [AC1-wlan-ssid-prof-guest]quit [AC1-wlan-view]ssid-profile name work [AC1-wlan-ssid-prof-work]ssid work [AC1-wlan-ssid-prof-work]quit ## 虚拟接入点(vpa)配置 [AC1-wlan-view]vap-profile name guest # 新建vap配置,名称为guest [AC1-wlan-vap-prof-guest]service-vlan vlan-pool sta-pool101 # 应用vlan地址池 [AC1-wlan-vap-prof-guest]security-profile guest # 应用安全配置 [AC1-wlan-vap-prof-guest]ssid-profile guest # 应用SSID [AC1-wlan-vap-prof-guest]quit [AC1-wlan-view]vap-profile name work [AC1-wlan-vap-prof-work]service-vlan vlan-pool sta-pool102 [AC1-wlan-vap-prof-work]security-profile work [AC1-wlan-vap-prof-work]ssid-profile work [AC1-wlan-vap-prof-work]quit ## 开启无线电信号 [AC1-wlan-view]ap-group name guest [AC1-wlan-ap-group-guest]vap-profile guest wlan 1 radio 0 # 应用虚拟接入点配置,wlanid为1,radio 0意思是使用2.4GHz的频段 [AC1-wlan-ap-group-guest]vap-profile guest wlan 1 radio 1 # 配置双射频,radio 1=5GHz [AC1-wlan-ap-group-guest]quit [AC1-wlan-view]ap-group name work [AC1-wlan-ap-group-work]vap-profile work wlan 1 radio 0 [AC1-wlan-ap-group-work]vap-profile work wlan 1 radio 1

 

此时 网络拓扑图显示信号覆盖范围,如下图所示:

步骤6 配置客户端使用的地址池,结束。检验配置成果。 ## 配置核心交换机 [LSW1]vlan batch 101 102 [LSW1]ip pool 101 [LSW1-ip-pool-101]network 192.168.10.0 mask 24 [LSW1-ip-pool-101]gateway-list 192.168.10.1 [LSW1-ip-pool-101]quit [LSW1]ip pool 102 [LSW1-ip-pool-102]network 192.168.20.0 mask 24 [LSW1-ip-pool-102]gateway-list 192.168.20.1 [LSW1-ip-pool-102]quit [LSW1]int vlanif 101 [LSW1-Vlanif101]ip ad 192.168.10.1 24 [LSW1-Vlanif101]dhcp select global [LSW1]int vlanif 102 [LSW1-Vlanif102]ip ad 192.168.20.1 24 [LSW1-Vlanif102]dhcp select global

 

 

步骤7  在终端设备连接AP,并输入密码 

双击 phone,具体链接过程如下图:

笔记本联网模拟:

 

笔记本单独联通后拓扑图如下图:

有时间的话可以测试一下网络连通性:
