•
IP addresses: You have the choice between DHCP and Static:
o Use DHCP (default): If you select Use DHCP, the DHCP scope in the DHCP server must be
configured with the following options:
o
Option Code
Description
1
Subnet mask
3
Default gateway
6
DNS server
15
Domain name
66
TFTP server
151
SVP server
152
OAI gateway
Static IP: If you use a static IP address, configure the following parameters. Enter IP addresses and
masks as a single number, with no periods in between:
ƒ Phone IP
ƒ Default Gateway
ƒ Subnet Mask
ƒ TFTP Server IP: Address of the server that will be used for firmware updates
ƒ Syslog Server IP
ƒ Time Server IP
ƒ SVP IP address
ƒ Alcatel TFTP Info
ƒ OAI Server IP
•
SSID: voice
•
Security: WPA-PSK
•
Passphrase: procurve
•
Reg Domain: Regulatory domain. This should be:
o 01 for North America
o 02 for Europe
Note: From the Network Config menu itself, you can view the Reg Domain but not modify it. To modify the
Reg Domain, while in the Network Config menu click on the bottom right phone button (the loudspeaker key,
the one with the volume icon).
•
Once the regulatory domain is set, choose the 802.11 mode:
o a
o b and b/g mixed
o g only
On the WESM, you can now see the phone in Device Association > Wireless stations. You can view the MAC
address, IP address, WLAN, VLAN, and Radio Index.
On the phone you can view similar information in System > Network > Info.

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
But these options apply to 802.1X authentication only, which is not supported by the Alcatel-Lucent wireless phone.
For this reason, the WESM is configured with WPA2-PSK (WP2 with a pre-shared key) authentication.
5.2 Configure self-healing
The self-healing feature enables associating neighbors to each radio port. In case of failure of a radio port, the
neighbors increase their transmit power to provide coverage and compensate for the failed RP. You can also enable
interference avoidance, which causes radios to change their channel settings to avoid interfering with surrounding
radios.
To enable self-healing:
1. From the Special Features > Self Healing > Configuration tab, check the Enable Neighbor Recovery box, then
click Apply.
2. Then from the Neighbor Details tab click Detect Neighbors.
3. You can now edit an RP radio to check that the other radios with same 802.11 mode (a or b/g) have been
listed as neighbors.

5.3 Test 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. To determine the switch port associated with this MAC address, use ProCurve Manager’s Find Node tool.
o
Use the command show lldp info remote all on the switch if the radio ports are connected at layer 2.
o
Or use show arp if the radio ports have IP addresses.
4. From a machine on the network launch a ping to the phone IP address.
5. From the switch CLI or Web agent disable the port of the RP to which the phone is associated. The phone
should lose one or two pings, then subsequent pings should be successful again as the phone connects to the
other RP.
6. You can initiate a phone call to another phone on the network and then disable the radio port. The
communication link should remain on, and the voice should be lost for less than one second.
6. SVP and voice prioritization
Voice prioritization enables the radio ports to monitor all packets in a WLAN. If the IP header indicates a voice packet,
the WESM marks the packet as high priority.
SpectraLink Voice Prioritization (SVP) is an IEEE 802.11-compliant QoS mechanism developed by SpectraLink. It is
implemented in wireless phones, APs/RPs, and SpectraLink servers. SVP minimizes latency for voice traffic by
establishing priority queues for voice packets, and enables voice packets to be transmitted in a coordinated fashion
without any back-off interval, reducing delays.
6.1 Enable voice prioritization
To enable SVP and Voice Prioritization on the voice WLAN:
1. In the Network Setup > WLAN Setup > Edit window, go to the Advanced panel and put check marks in the
boxes to enable these settings:
o
o
Use Voice Prioritization
Enable SVP

2. Set the Access Category to Voice.
3. On the wired network, configure the VLAN of the voice WLAN as voice.
6.2 Configure WMM
Another possibility for prioritizing voice traffic is to configure WiFi Multimedia (WMM). WMM automatically defines four
classes of traffic that will be queued and prioritized accordingly. However, SpectraLink does not recommend enabling
WMM simultaneously with SVP.
For more information on WMM configuration on the WESM, please refer to ProCurve Application Note AN-M12, Using
802.11e and WMM on the ProCurve Wireless Edge Services Module.
