9. Set the WLAN parameters as follows:
o 1. Ssid: voice
o 2. Security Mode: Choose Auto (AKM)
o 3. Leave unconfigured
o 4. Leave unconfigured
o 5. Key style: ASCII
o 6. Pre-shared key: procurve
o 7. 802.11 mode: Auto-RSSI
Leave the other settings as they are.
10. On the WESM, you can now see the phone in Device Association > Wireless stations. You can see the
phone’s MAC Address, IP Address, WLAN, VLAN, and Radio Index:
Note that the phone is now connected to the RP represented by Radio Index 3.
11. Check connectivity to the phone by running a ping to its IP address from another machine or other device on
the same LAN:
5. 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 happens when a phone moves between two radio ports associated to different WESM modules. The
voice WLAN is associated with different VLANs (and subnets) on the two modules. In this case, the phone keeps its
originating IP address but the voice flow is tunneled by the current module to the home module.
For more information on L2/L3 roaming configurations, please refer to ProCurve Application Note AN-M3, How to
configure L2 and L3 wireless roaming.
5.1 Fast roaming options
Normally, to enable a phone to transition faster between two radio ports and reduce the roaming time, you can
configure these options:
• PMK caching
• Opportunistic key caching
• Pre-authentication
These options apply to 802.1X authentication only, which is supported with EAP-TLS on the Cisco phone. This
application note, however, presents authentication with WPA2.
