Información general del controlador inalámbrico Unified Access CT5760
El CT5760 WLC es el primer controlador basado en software Cisco IOS-XE® construido con ASIC inteligente y diseñado para implementarse como un controlador centralizado en la arquitectura inalámbrica unificada de próxima generación. La plataforma también es compatible con la nueva funcionalidad de movilidad con los switches de acceso convergente serie 3850.
Los controladores CT5760 se suelen implementar cerca del núcleo. Los puertos de enlace ascendente conectados al switch principal se pueden configurar como puertos troncales EtherChannel para garantizar la redundancia de puerto. Este nuevo controlador es un controlador inalámbrico extensible y de alto rendimiento, que puede ampliarse hasta 1000 AP y 12 000 clientes. El controlador tiene seis puertos de datos de 10 Gbps para una capacidad total de 60 Gbps.
La serie 5760 funciona junto con los puntos de acceso Cisco Aironet, Cisco Prime Infrastructure y Cisco Mobility Services Engine para admitir aplicaciones de servicios de ubicación, vídeo, voz y datos inalámbricos fundamentales para la empresa.
Información general sobre los switches Catalyst 3850 de Unified Access
Cisco Catalyst serie 3850 es la última generación de switches apilables de nivel de acceso de clase empresarial que proporcionan una convergencia completa entre redes por cable e inalámbricas en una única plataforma. Con la tecnología del software IOS-XE, el servicio inalámbrico es compatible con el protocolo de control y aprovisionamiento de puntos de acceso inalámbricos (CAPWAP). El nuevo ASIC de plano de datos de Unified Access (UADP) de Cisco alimenta el switch y permite la aplicación uniforme de políticas por cable e inalámbricas, la visibilidad de las aplicaciones, la flexibilidad y la optimización de las aplicaciones. Esta convergencia se basa en la resistencia de la nueva y mejorada Cisco StackWise-480. Los switches Catalyst de Cisco serie 3850 admiten alimentación a través de Ethernet Plus (PoE+) IEEE 802.3at completa, módulos de red modulares y reemplazables in situ, ventiladores redundantes y fuentes de alimentación.
5760 Configuración Inicial del WLC
Esta sección describe los pasos para configurar correctamente el WLC 5760 para alojar servicios inalámbricos.
Configurar
Guión de configuración
--- 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

Configuración necesaria para que los puntos de acceso se unan
- Configure los requisitos previos inalámbricos.
Para habilitar los servicios inalámbricos, el 3850 debe ejecutar una licencia ipservices o ipbase.
- Active la función inalámbrica en el switch.
- Habilitar la gestión inalámbrica
sw-3850-1(config)#wireless management interface vlan <1-4095>
- Definir el MC
Se debe definir un MC para permitir que los AP se unan.
Si este 3850 será el MC, ingrese el comando wireless mobility controller:
sw-3850-1(config)#wireless mobility controller
- Si este 3850 funciona como agente de movilidad (MA), señale la dirección IP de MC con este comando:
sw-3850-1(config)#wireless mobility controller ip a.b.c.d
Y en el MC, ingrese estos comandos:
3850MC(config)#wireless mobility controller peer-group
3850MC(config)#wireless mobility controller peer-groupmember
ip w.x.y.z
- Habilitar la gestión inalámbrica
- Garantizar la disponibilidad de la licencia.
Asegúrese de que las licencias AP activas estén disponibles en el MC (el MA utiliza las licencias activadas en el MC):

Para que los AP se unan al controlador, la configuración del switchport debe configurarse como un puerto de acceso en la vlan de administración inalámbrica:
Si vlan 100 se utiliza para la interfaz de administración inalámbrica:
sw-3850-1(config)#interface gigabit1/0/10
sw-3850-1(config-if)#switchport mode access
sw-3850-1(config-if)#switchport access vlan 100Configure el acceso web.
