Interoperability between the Aastra Wireless Phone 312 and ProCurve Wireless Services 1. Introduction This document describes how the interoperability of the ProCurve wireless services solution and an Aastra wireless phone 312 can be used to provide a secure VoWLAN solution with the following services: • Secure wireless encryption with WPA/WPA2 • Fast roaming • Quality of Service on the wireless media, with WMM • Unscheduled Automated Power Save Delivery (uAPSD) 2.

Interoperability between the Aastra Wireless Phone 312 and ProCurve Wireless Services 4.1 Configure encryption on the WESM To configure the Wireless Edge Services Module for encryption: 1. On the Wireless Edge Services Module, go to Network Setup > WLAN Setup and create a new WLAN called voice. 2. Configure this WLAN as follows: o o o o SSID: voice VLAN ID: The VLAN to which you want the phone to be assigned. You must use the switch menu to tag this phone on the WESM uplink.

Set the parameters as follows: o o ASCII passphrase: procurve Check the boxes to enable all three Fast Roaming options: PMK Caching, Opportunistic Key Caching and Pre-Authentication. 4. Click OK to return to the main window. 5. On the main window Advanced section, check the Closed System box to enable it. 6.

If you use DHCP assignment, configure the following options on the DHCP server: Note: Illustration from Aastra Phone 312 User Guide. 7. Once the profile is configured click OK, then click Back as many times as needed to go back to the Main screen. If the profile is correctly configured, in the phone display’s upper left corner you will see a small icon showing the signal strength. 8.

Fast roaming Layer 2 roaming occurs when a phone that was associated to a radio port moves to another radio port adopted by the same WESM. The phone remains in the same VLAN. Layer 3 roaming occurs when a phone moves between two radio ports associated to different WESM modules. The voice WLAN is associated to different VLANs ( and subnets) on the two modules.

Interoperability between the Aastra Wireless Phone 312 and ProCurve Wireless Services 5.3 Test the roaming time You can determine the roaming time by first using the WESM to determine the radio port to which the phone is associated. To test roaming time: 1. From Device Association > Wireless Stations, note the radio’s Station Index. 2. Go to Device Association > Radio Adoption Statistics and determine the MAC address of the corresponding radio port. 3.

Go to Menu | System | Network | Profiles. 2. Edit the profile you created. 3. Specify the power save mode. This setting lets you specify which WLAN power save mode will be used during all voice connections. 6.

Interoperability between the Aastra Wireless Phone 312 and ProCurve Wireless Services To manually configure the phone’s power save mode, use the left softkey. You can select between: • Auto: In this mode, the device attempts to use uAPSD if the AP signals that it will support this. If the AP does not support uAPSD, the Aastra Phone 312 will use asynchronous PS-Poll. Support for uAPSD is supported can be determined in the Site survey mode.
