Release Notes for Cisco Spectrum Expert, Release 4.1.11
March 9, 2012
These release notes describe the open and resolved caveats for Cisco Spectrum Expert 4.1.11 release.
These release notes contain the following sections:
Cisco Spectrum Expert monitors the RF spectrum used by a variety of wireless network and communications technologies, such as Wi-Fi (802.11) WLANs. Spectrum Expert consists of hardware-based Cisco Spectrum Expert Sensor Wi-Fi (Sensor Card) and a GUI-based Cisco Spectrum expert software that provide complete visibility of the RF environment in which wireless network technologies operate.
Cisco Spectrum Expert Features
The Cisco Spectrum Expert provides the following features:
•A combined hardware and software technology that implements Cisco Spectrum Intelligence technology.
•Increased security, reliability, and performance of the 802.11 WLAN system.
Spectrum Expert consists of two primary components:
•Cisco Spectrum Expert Software—The Spectrum Expert Software analyzes data from the sensor and provides a GUI-based view of network and RF activity.
•CleanAir-enabled Cisco products and Cisco Spectrum Expert Sensor Wi-Fi (Sensor Card)—Spectrum sensors provide the hardware foundations for Cisco Spectrum Intelligence. Each Sensor card incorporates the SAgE ASIC, which is a spectrum analyzer on a chip. SAgE provides visibility for the RF spectrum in the unlicensed bands on which Wi-Fi WLANs operate.
The SAgE ASIC is in its second generation. Cisco Spectrum Expert Software support for the two versions of the Sensor Card requires specific versions of the application:
–SAgE 2 support as of Spectrum Expert 4.0.68 and later releases
–SAgE 1 support as of Spectrum Expert 3.3.52 and earlier releases
Cisco CleanAir-enabled Access Points
–Cisco Aironet 3500 Series Access Points—This access point was introduced in the Cisco Wireless LAN Controller release 184.108.40.206. The 220.127.116.11 release required CleanAir-enabled access points to be in SE Connect mode to work with Cisco Spectrum Expert application. This support was enhanced to include support for Local and Monitor modes in Cisco Wireless LAN Controller 18.104.22.168 release.
–Cisco Aironet 3600 Series Access Points—This access point was introduced with Cisco Wireless LAN Controller software release 22.214.171.124 and supported Cisco Spectrum Expert with the access point SE Connect, Local, and Monitor modes.
Note The Cisco 3600 Access Point was introduced in Cisco Wireless LAN Controller 126.96.36.199 release. If your network deployment uses Cisco 3600 Access Points with release 188.8.131.52, we highly recommend that you upgrade to the Cisco Wireless LAN Controller 184.108.40.206 release.
See the Cisco Wireless Solutions Software Compatibility Matrix for more information on supported controller software release for the access points.
Note Spectrum Expert release 4.1 supports only the second generation Cisco production sensor cards. The cards can be identified by the model number of 210c and an 11-character alphanumeric serial number. Older cards can be used and are supported in 3.3.52 version of Spectrum Expert. Spectrum Expert version 4.0 and later is not supported with SAgE1 card. If users try to use Specturm Expert 4.0 version with a SAgE1 card, an error is displayed.
