統一接入CT5760無線控制器的背景資訊
CT5760 WLC是第一個使用智慧ASIC構建的基於Cisco IOS-XE®軟體的控制器，旨在作為下一代統一無線架構中的集中控制器進行部署。該平台還支援融合接入3850系列交換機的新移動功能。
CT5760控制器通常部署在核心附近。連線到核心交換機的上行鏈路埠可以配置為EtherChannel中繼埠，以確保埠冗餘。此新控制器是一個可擴展的高效能無線控制器，最多可擴展1000個AP和12,000個客戶端。控制器有六個10 Gbps資料埠，總容量為60 Gbps。
5760系列與Cisco Aironet AP、Cisco Prime Infrastructure和Cisco Mobility Services Engine配合使用，以支援業務關鍵型無線資料、語音、影片和位置服務應用。
統一接入Catalyst 3850交換機的背景資訊
Cisco Catalyst 3850系列是下一代企業級堆疊式接入層交換機，可在單個平台上實現有線和無線之間的完全融合。無線服務由IOS-XE軟體支援，通過無線接入點的控制和調配(CAPWAP)協定提供支援。思科的全新統一接入資料平面(UADP)ASIC為交換機提供支援，實現統一的有線 — 無線策略實施、應用可視性、靈活性和應用最佳化。此融合基於新型Cisco StackWise-480的恢復能力。Cisco Catalyst 3850系列交換機支援完整的IEEE 802.3at Power over Ethernet Plus(PoE+)、模組化和現場可更換網路模組、冗餘風扇和電源。
5760 WLC初始設定
本節概述成功配置5760 WLC以託管無線服務的步驟。
設定
安裝指令碼
--- 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
Current interface summary
Any interface listed with OK? value "NO" does not have a valid configuration

management network from the above interface summary: vlan1
Configuring interface Vlan1:
Configure IP on this interface? [yes]: yes
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

接入點加入所需的配置
- 配置無線先決條件。
為了啟用無線服務，3850必須運行ipservices或ipbase許可證。
- 在交換機上啟用無線。
- 啟用無線管理
sw-3850-1(config)#wireless management interface vlan <1-4095>
- 定義MC
必須定義MC才能允許AP加入。
如果此3850將是MC，請輸入wireless mobility controller指令：
sw-3850-1(config)#wireless mobility controller
- 如果這3850是作為行動代理(MA)執行，請使用以下命令將其指向MC IP位址：
sw-3850-1(config)#wireless mobility controller ip a.b.c.d
在MC上，輸入以下命令：
3850MC(config)#wireless mobility controller peer-group
3850MC(config)#wireless mobility controller peer-groupmember
ip w.x.y.z
- 啟用無線管理
- 確保許可證可用性。
確保MC上有活動的AP許可證（MA使用在MC上啟用的許可證）：
sw-3850-1#show license right-to-use summary
License Name Type Count Period left
-----------------------------------------------
ipservices permanent N/A Lifetime

License Level on Reboot: ipservices
Evaluation AP-Count: Disabled
Total AP Count Licenses: 50
AP Count Licenses In-use: 1
AP Count Licenses Remaining: 49若要啟用3850上的AP計數許可證，請輸入以下命令，並在MC上輸入所需的AP計數：
sw-3850-1#license right-to-use activate apcountslot <#> acceptEULA 配置AP發現過程。
為了讓AP加入控制器，必須將交換器連線埠組態設定為無線管理vlan中的存取連線埠：
如果VLAN 100用於無線管理介面：
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設定Web存取。
