    Known issues and limitations

    - Important. It is essential to follow the “General guidelines when deploying Ascom i62 handsets in 802.11a/n/ac environments” on page 16 and not exceed 8 enabled channels in the system. Not doing so might cause the Ascom i62 to randomly lose connection to the network for a few seconds (“no network” including audible signal)

    - Note that Cisco AP 1830, 1850 and 3800 does not support CCX and DTPC. Refer to Cisco release notes for additional information.

    - Call Admission Control/TSPEC. Beacon and Probe response information in QBSS IE - "Available Admission Capacity" does not decrease with added calls. Hence i62 might still consider access points that have reached their capacity limit to be roaming candidates. Result is loss of speech. AP2800/3800 only. Investigation is ongoing.

    For additional information regarding the known issues please contact interop@ascom.com or support@ascom.com

    Compatibility information Supported access points with Cisco WLC version 8.3.102: AP1140, AP1250, AP1260, AP1600, AP1700, AP2600, AP2700, AP3500, AP3600, AP3700, 3800 1830 and 1850 Supported controller platforms with Cisco WLC version 8.3.102: 2500 series WLC 5500 series WLC Cisco Flex 7500 /8500 controllers Cisco WiSM2 for Catalyst 6500 Series Switches Cisco Virtual Wireless Controllers

    General conclusion Overall the outcome of interoperability verification, including association, authentication and roaming produced very good results. If U-APSD shall be used in the handset it is very important that the WMM parameters in the Cisco WLC are set correctly since U-APSD handles a bi-directional data stream where the up and downlink must be transmitted within the same EDCA Access Category. To use U-APSD, make sure to set QoS to Platinum for the current WLAN profile and set WMM to “Required”. Also set EDCA profile for 802.11b/g/n and 802.11a/n/ac to "Voice Optimized" and disable low latency MAC.

    APPENDIX A: TEST CONFIGURATIONS

    Cisco WLC 5508 Version 8.3.102 In the following chapter you will find screenshots and explanations of basic settings in order to get a Cisco WLC WLAN system to operate with an Ascom i62. Please note that security settings were modified according to requirements in individual test cases.

    Security settings (PSK) Example of how to configure the system for PSK (WPA2-AES)

    Security profile WPA2-PSK, AES encryption

    - Select WPA2 Policy with AES encryption. - Select PSK and enter a key (Here in ASCII format)

    802.1X authentication (PEAP-MSCHAPv2). Example of how to configure the system for .1X authentication

    Configuration of authentication using external Radius sever, 802.1X (Step 1). In this example is WPA2- AES used. Select 802.1X as Authentication Key Management. Note. To use CCKM, replace 802.1X with CCKM check box. The “security mode” in the i62 has to be set to “Advanced” and CCKM has to be selected as “Authentication Key Management” instead of the default 802.1X.

    Example of authentication configuration using external Radius sever (Step 2). Select the server to use. The server is configured under tab Security/Radius. See configuration of server below.

    Configuration of authentication using external Radius sever (Step 3). The IP address and the secret must correspond to the IP and the credential used by the Radius server. Tes
