简介
本文档介绍在5760无线LAN控制器(WLC)和3850交换机上安装和准备无线服务的步骤。本文档介绍两个平台的初始配置和接入点(AP)加入过程。
先决条件
要求
本文档没有任何特定的要求。
使用的组件
本文档中的信息基于以下软件和硬件版本：
- 统一接入CT5760无线控制器 — 版本3.02.02SE
- 统一接入Catalyst 3850交换机 — 版本3.02.02SE
本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您使用的是真实网络，请确保您已经了解所有命令的潜在影响。
统一接入CT5760无线控制器的背景信息
CT5760 WLC是首款基于Cisco IOS-XE®软件的控制器，内置智能ASIC，旨在作为下一代统一无线架构中的集中控制器进行部署。该平台还支持融合接入3850系列交换机的新移动功能。
CT5760控制器通常部署在核心附近。连接到核心交换机的上行链路端口可以配置为EtherChannel中继端口，以确保端口冗余。这款新控制器是可扩展的高性能无线控制器，可扩展至1000个AP和12,000个客户端。控制器有6个10 Gbps数据端口，总容量为60 Gbps。
5760系列与Cisco Aironet AP、Cisco Prime基础设施和思科移动服务引擎配合使用，以支持业务关键型无线数据、语音、视频和位置服务应用。
Unified Access Catalyst 3850交换机的背景信息
Cisco Catalyst 3850系列是下一代企业级堆叠式接入层交换机，可在单一平台上提供有线和无线之间的完全融合。无线服务由IOS-XE软件支持，通过无线接入点控制和调配(CAPWAP)协议受支持。思科新的统一接入数据平面(UADP)ASIC为交换机供电，并实现统一的有线 — 无线策略实施、应用可视性、灵活性和应用优化。此融合基于新的和改进的Cisco StackWise-480的恢复能力。Cisco Catalyst 3850系列交换机支持全IEEE 802.3at增强型以太网供电(PoE+)、模块化且可现场更换的网络模块、冗余风扇和电源。
5760 WLC初始配置
本节概述成功配置5760 WLC以托管无线服务的步骤。
配置
设置脚本
--- System Configuration Dialog ---
Enable secret warning
----------------------------------
In order to access the device manager, an enable secret is required
If you enter the initial configuration dialog, you will be prompted for the
enable secret
If you choose not to enter the intial configuration dialog, or if you exit setup
without setting the enable secret,
please set an enable secret using the following CLI in configuration mode-
enable secret 0 <cleartext password>
----------------------------------
Would you like to enter the initial configuration dialog? [yes/no]: yes
At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.
Basic management setup configures only enough connectivity
for management of the system, extended setup will ask you
to configure each interface on the system
Would you like to enter basic management setup? [yes/no]: yes
Configuring global parameters:
Enter host name [Controller]: w-5760-1
The enable secret is a password used to protect access to
privileged EXEC and configuration modes. This password, after
entered, becomes encrypted in the configuration.
Enter enable secret: cisco
The enable password is used when you do not specify an
enable secret password, with some older software versions, and
some boot images.
Enter enable password: cisco
The virtual terminal password is used to protect
access to the router over a network interface.
Enter virtual terminal password: cisco
Configure a NTP server now? [yes]:
Enter ntp server address : 192.168.1.200
Enter a polling interval between 16 and 131072 secs which is power of 2:16
Do you want to configure wireless network? [no]: no
Setup account for accessing HTTP server? [yes]: yes
Username [admin]: admin
Password [cisco]: cisco
Password is UNENCRYPTED.
Configure SNMP Network Management? [no]: no

IP address for this interface: 192.168.1.20
Subnet mask for this interface [255.255.255.0] : 255.255.255.0
Class C network is 192.168.1.0, 24 subnet bits; mask is /24
Wireless management interface needs to be configured at startup
It needs to be mapped to an SVI that's not Vlan 1 (default)
Enter VLAN No for wireless management interface: 120
Enter IP address :192.168.120.94
Enter IP address mask: 255.255.255.0

接入点加入所需的配置
- 配置无线必备条件。
要启用无线服务，3850必须运行ipservices或ipbase许可证。
- 在交换机上启用无线。
- 启用无线管理
sw-3850-1(config)#wireless management interface vlan <1-4095>
- 定义MC
必须定义MC才能允许AP加入。
如果此3850将是MC，请输入无线移动控制器命令：
sw-3850-1(config)#wireless mobility controller
- 如果此3850作为移动代理(MA)运行，则使用以下命令将其指向MC IP地址：
sw-3850-1(config)#wireless mobility controller ip a.b.c.d
在MC上，输入以下命令：
3850MC(config)#wireless mobility controller peer-group
3850MC(config)#wireless mobility controller peer-groupmember
ip w.x.y.z
- 启用无线管理
- 确保许可证可用性。
确保活动AP许可证在MC上可用（MA使用在MC上激活的许可证）：

sw-3850-1#license right-to-use activate apcountslot <#> acceptEULA 配置AP发现过程。
要使AP加入控制器，必须将交换机端口配置设置为无线管理vlan中的接入端口：
如果VLAN 100用于无线管理接口：
sw-3850-1(config)#interface gigabit1/0/10
sw-3850-1(config-if)#switchport mode access
sw-3850-1(config-if)#switchport access vlan 100配置 Web 访问。
