The platforms that run the Cisco WCS, and the system requirements for the WCS


The Cisco Wireless Control System (WCS) runs on Windows 2003 SP1 or a later server, or on Red Hat Linux AS/ES version 4.0. The Cisco WCS provides the scalability required in order to manage hundreds of Cisco Wireless LAN Controllers (WLC), which in turn can manage thousands of Access Points (APs).

The Cisco WLCs can be located on the same LAN as the Cisco WCS, or across a wide-area link. This makes the Cisco WCS the ideal wireless LAN management platform for even the largest enterprise environments.

For the Windows platform, Cisco WCS can be run as a normal Windows application, or it can be installed as a service that operates in the background and resumes operation after a reboot. The Cisco WCS can be run as a normal Linux application.

These are the Cisco WCS system requirements:-

System Requirements

Cisco WCS can be run on a workstation/server class system and access points can be distributed unevenly across controllers. The following requirements must be met for the different components.

High-End Server

Up to 3000 Cisco Aironet lightweight access points, 1250 standalone access points, and 750 Cisco wireless LAN controllers

3.16-GHz Intel Xeon or Quad processor.


200-GB minimum free disk space on your hard drive.

Note     The free disk space listed is a minimum requirement but may be different for your system, depending on the number of backups.

Standard Server

Up to 2000 Cisco Aironet lightweight access points, 1000 standalone access points, and 450 WLCs.

3.2-GHz Intel Dual Core processor.

2.13-GHz Intel Quad Core X3210 processor.

2.16-GHz Intel Core2 processor.

4 GB of RAM.

80-GB minimum of free disk space on your hard drive.

Low-End Server

Up to 500 Cisco Aironet lightweight access points, 200 standalone access points, and 125 Cisco wireless LAN controllers.

3.06-GHz Intel processor.

1.86-GHz Intel Dual core processor.


50-GB minimum free disk space on your hard drive.

Supported Operating Systems

The following operating systems are supported:

Windows 2003/SP2 and Windows 2003 R2/SP2 32-bit installations with all critical and security Windows updates installed.

Windows 2003/SP2 64-bit installations are not supported.

Windows 2003 32-bit installations provide support for up to 64 GB of RAM provided Physical Address Extension (PAE) is enabled. Refer to Windows documentation for instructions on enabling this mode.

Red Hat Linux Enterprise Server 5.X 32-bit operating system installations.

Red Hat Linux Enterprise Server 5.X 64-bit operating system installations are not supported.

Mozilla Firefox 2.0. or 3.0.

Microsoft Windows Server 2003 and Red Hat Linux version support on VMware ESX version 3.0.1 and above with either local storage or SAN over fiber channel.

Note     Individual operating systems running WCS in VmWare must follow the specifications for the size of WCS you intend to use.

Client Requirements

The Cisco WCS user interface requires Internet Explorer 6.0/SP1, Internet Explorer 7.0 with the 9.0.X or later Flash plugin, or Mozilla Firefox 2 or 3. Cisco recommends latest version of Mozilla Firefox 3 for best performance. If you are using Internet Explorer 6.0, we recommend that you use version 7.0 because support for Internet Explorer 6.0 will be discontinued in a future release. Browsing on Windows 2003 Cisco WCS servers is not recommended because recommended Windows 2003 security settings cause browsing problems. The client running the browser must have a minimum of 1 GB of RAM and a 2-GHz processor. The client device should not be running any CPU or memory-intensive applications.

Note     The screen resolution should be set to 1024 x 768 pixels for both WCS and Navigator.

Supported WLC Releases:-

Cisco WCS can manage the following releases of the WLC as found on various controllers (such as 2106, 4400 series, WiSM, and so on):


•     5.0
