第1题      2020年下半年 网络工程师 下午试卷 案例

 
某校园宿舍WLAN网络拓扑结构如图1-1所示,数据规划如表1-1内容所示。该网络采用敏捷分布式组网在每个宿舍部署一个AP,AP连接到中心AP,所有AP和中心AP统一由AC进行集中管理,为每个宿舍提供高质量的WLAN网络覆盖。

 

 
问题:1.1   (10分)
补充命令片段的配置。
1.Router 的配置文件
[Huawei] sysname Router
[Router] vlan batch(1)
[Router] interface gigabitethernet 1/0/0
[Router GigabitEthernet 1/0/0] port link-type trunk
[Router GigabitEthernet 1/0/0] port trunk allow-pass vlan 101
[Router GigabitEthernet 1/0/0] quit
[Router] interface vlanif 101
[Router-Vlanifl01]ip address (2)
[Router-Vlanifl01]quit
2.AC的配置文件
#配置AC和其他网络设备互通
[HUAWEI]sysname (3)
[AC] vlan batch 100 101
[AC] interface gigabitethernet 0/0/1
[AC-GigabitEthernet0/0/1] port link -type trunk
[AC-GigabitEthernet0/0/1] port trunk pvid vlan 100
[AC-GigabitEthernet0/0/1] port trunk allow-pass vlan 100
[AC-GigabitEthernet0/0/1] port-isolate(4) //实现端口隔离
[AC-GigabitEthernet0/0/1] quit
[AC] interface gigabitethernet 0/0/2
[AC-GigabitEthernet0/0/2] port link-type trunk
[AC-GigabitEthernet0/0/2] port trunk allow-pass vlan 101
[AC-GigabitEthernet0/0/2] quit
#配置中心AP和AP上线
[AC] wlan
[AC-wlan-view] ap-group name ap-groupl
[AC-wlan-ap-group-ap-group1] quit
[AC-wlan-view] regulatory-domain-profile name default
[AC-wlan-regulate-domain-default] country-code (5)
[AC-wlan-regulate domain-default] quit
[AC-wlan-view]ap-group name ap-group1
[AC-wlan-ap-group-ap-group1] regulatory-domain-profile(6)
Warning: Modifying the country code will clear channel, power and antenna gain config
Of the config send reset the AP Continue?[Y/N]:y
[AC-wlan-ap-group-ap-group1]quit
[AC-wlan-view]quit
[AC]capwap source interface(7)
[AC] wlan
[AC-wlan-view] ap auth mode mac-auth
[AC-wlan-view] ap-id 0 ap-mac 68a8-2845-62fd//中心AP的MAC地址
[AC-wlan-ap-0] ap-name central AP
Warning: This operation may cause AP reset Continue?[Y/N]:y
[AC-wlan-ap-0] ap-group ap-group1
Warning: This operation may cause AP reset.If the country code changes,it will clear channel,power and antenna gain configuration s of the radio,Whether to continue?[Y/N]:y
[AC- wlan-ap-0] quit
其他相同配置略去
#配置WLAN业务参数
[AC-wlan-view] security-profile name wlan-net
[AC-wlan-sec-prof-wlan-net] security wpa-wpa2 psk pass-phrase(8) aes
[AC-wlan-sec-prof-wlan-net] quit
[AC-wlan-view] ssid-profile name wlan-net
[AC-wlan-ssid-prof-wlan-net] ssid(9)
[AC-wlan-ssid-prof-wlan-net] quit
[AC-wlan-view] vap-profile name wlan-net
[AC-wlan-vap-prof-wlan-net] forward-mode tunnel
[AC-wlan-vap-prof-wlan-net] service-vlan vlan-id(10)
[AC-wlan-vap-prof-wlan-net] security-profile wlan-net
[AC-wlan-vap-prof-wlan-net] ssid-profile wlan-net
[AC-wlan-vap-prof-wlan-net] quit
[AC-wlan-view] ap-group name ap-group1
[AC-wlan-ap-group-ap-groupl] vap-profile wlan-net wlan 1 radio 0
[AC-wlan-ap-group-ap-group1] vap-profile wlan-net wlan 1 radio 1
[AC-wlan-ap-group-ap-group1] quit
