Cisco WLC接口解释

 接口 :

virtual interface : ( 二三层漫游)
 
用于支持移动性管理需求 (客户端漫游时的网关)
DHCP中继
嵌入式三层安全
guest web认证 (web认证重定向地址)
VPN终结
 
客户端在不同控制器和客户端之间通信
 
 
在一个网络里其他设备不同配置和virtual interface相同的地址 不能被映射到任何物理口 不能存在与路由表中所有控制器在一个移动组里virtual interface必须配置相同的IP
 
 
 
Enter the following parameters:
• Any fictitious, unassigned, and unused gateway IP address
• DNS gateway hostname
 
To ensure connectivity and web authentication, the DNS server should always point to the virtual interface.
If a DNS hostname is configured for the virtual interface, then the same DNS host name must be configured  on the DNS server(s) used by the client.
 
 
 
config interface address dynamic-interface/management/service-port/virtual x.x.x.x
config interface hostname virtual

Service-Port Interface
 
默认网关不能设置为service接口IP
控制器上可以定义远端网络到达服务接口的路由
用于控制器的带外网管
 
通常预留一个VLAN和子网供WLC和LWAPP使用,可将管理子网中的IP分配给管理接口和AP管理接口
外部管理数据流(web,telnet,ssh,aaa)和LWAPP都到达此地址
由于LAP分布于不同的位置,LAP的数据流视为外部数据流
 
config route add network-ip-addr ip-netmask gateway
可通过config route add x.x.x.x x.x.x.x来定义远程工作站到控制器的路由
 
 
show interface detailed service-port
 
Interface Name................................... service-port
MAC Address...................................... 00:0c:29:16:0c:f0
IP Address....................................... 172.16.1.254
IP Netmask....................................... 255.255.255.0
DHCP Protocol.................................... Disabled
AP Manager....................................... No
Guest Interface.................................. No
 
 
 
动态接口 : ( 桥接无线客户端的接口)
即vlan 接口,被用户创建用做客户端的vlan,也称用户口
一台控制器最多支持512个动态接口 客户端关联到无线接口的DHCP中继
二层管理口 , 三层AP管理口
所有的动态口必须在不同的VLAN或IP子网中
 
 
 
Wireless Controllers Maximum VLANs
Cisco Virtual Wireless Controller 512
Cisco Wireless Controller Module for ISR G2 16
Cisco 2500 Series Wireless Controllers 16
Cisco 5500 Series Wireless Controller 512
 
 
Cisco Catalyst 6500 Series Wireless Services Module2 (WiSM2) 512
Cisco Flex 7500 Series Cloud Controller 4,096
Cisco 8500 Series Controller 4,096
 
If you are using DHCP proxy and/or a RADIUS source interface, ensure that the dynamic interface has
a valid routable address. Duplicate or overlapping addresses across controller interfaces are not supported.
 
We recommend using tagged VLANs for dynamic interfaces
 
 
 
 
AP-manager interface
控制器和AP之间的3层通信
WLC在此接口上侦听LAP试图发现控制器时发送的子网广播 新版本复用了manage interface
用做AP到控制器之间的CAPWAP/LWAPP隧道间的关联和通信
