SIP prviders are utside the scpe f this Applicatin Nte. 8. Click n the red icn t exit the Prfile menu. 9. The phne screen displays a message that indicates that a rebt is mandatry t activate the new settings. Click Yes t rebt. 4.2.2 Cnfigure the Siemens phne frm the Web interface: The Web cnfiguratr is the Web interface fr the Siemens phne. It allws making all settings n the phne via a PC. T cnnect t the phne Web cnfiguratr fr the first time: 1. On the phne display screen, select the Scan key t have the phne search fr and assciate t an pen WLAN (n encryptin, n authenticatin). 2. Cnnect a PC t the same WLAN as the phne, pen a web brwser and access the Web cnfiguratr at: http://<phne_ip_address> 3. On the Web cnfiguratr screen g t Admin and chse Netwrk > Prfile Selectin frm the left panel. Yu see a windw frm which yu can define a new prfile r edit an existing ne. 4. Fr this example, click Edit t edit the Vice prfile. Yu can chse ther links t cnfigure IP addresses (static r DHCP), IP Ruting, WLAN parameters and WLAN Security by pening the crrespnding menus frm the links in the left panel. HP PrCurve Netwrking 6
Interperability between PrCurve WESM zl and Siemens Gigaset SL75 wireless phne 5. G t the Netwrk > WLAN Security windw and cnfigure WPA-PSK fr the Vice prfile with the fllwing parameters: Encryptin: WPA-PSK(TKIP) Pre-Shared Key: prcurve Authenticatin: Nne 4.3 Cnfirm the phne n the WESM G t the WESM and cnfirm that yu can nw see the phne in Device Assciatin > Wireless Statins: Nte that yu can view the phne s MAC address, IP address, WLAN, VLAN, Radi Index, etc. 5. Fast raming Layer 2 raming ccurs when a phne that was assciated t a radi prt mves t anther radi prt adpted by the same WESM. The phne remains in the same VLAN. Layer 3 raming happens when a phne mves between tw radi prts assciated t different WESM mdules. The vice WLAN is assciated with different VLANs (and subnets) n the tw mdules. In this case, the phne keeps its riginating IP address but the vice flw is tunneled by the current mdule t the hme mdule. Fr mre infrmatin n L2/L3 raming cnfiguratins, please refer t PrCurve Applicatin Nte AN-M3, Hw t cnfigure L2 and L3 wireless raming. HP PrCurve Netwrking 7
Interperability between PrCurve WESM zl and Siemens Gigaset SL75 wireless phne 5.1 Fast raming ptins T enable a phne t transitin faster between tw radi prts and reduce the raming time, yu can cnfigure these ptins: PMK caching Opprtunistic key caching Pre-authenticatin These ptins are available with 802.1X authenticatin. The Siemens Gigaset SL75 WLAN phne supprts 802.1X authenticatin with the fllwing prtcls: LEAP EAP-TLS, which requires imprting a certificate t the phne Nte that PEAP is nt supprted in the Siemens phne, which is why this applicatin nte uses WPA2-PSK. 5.2 Cnfigure self-healing The self-healing feature enables assciating neighbrs t each radi prt. In case f failure f a radi prt, the neighbrs increase their transmit pwer t prvide cverage and cmpensate fr the failed RP. Yu can als enable interference avidance, which causes radis t change their channel settings t avid interfering with surrunding radis. T enable self-healing: 1. In the WESM, frm the Special Features > Self Healing > Cnfiguratin tab, check the Enable Neighbr Recvery bx, then click Apply. 2. Then frm the Neighbr Details tab click Detect Neighbrs. 3. Yu can nw edit an RP radi t check that the ther radis with same 802.11 mde (a r b/g) have been listed as neighbrs. HP PrCurve Netwrking 8
Interperability between PrCurve WESM zl and Siemens Gigaset SL75 wireless phne 5.3 Test raming time Yu can determine the raming time by first using the WESM t determine the radi prt t which the phne is assciated. T test raming time: 1. Frm Device Assciatin > Wireless Statins, nte the radi s Statin Index. 2. G t Device Assciatin > Radi Adptin Statistics and determine the MAC address f the crrespnding radi prt. 3. T determine the switch prt assciated with this MAC address, use PrCurve Manager s Find Nde tl. Use the cmmand shw lldp inf remte all n the switch if the radi prts are cnnected at layer 2. Or use shw arp if the radi prts have IP addresses. 4. Frm a machine n the netwrk launch a ping t the phne IP address: 5. Frm the switch CLI r Web agent disable the prt f the RP t which the phne is assciated. The phne shuld lse ne r tw pings, then subsequent pings shuld be successful again, indicating the phne has assciated t a different RP: 6. Cnfiguring 802.11e and UAPSD This sectin details hw t cnfigure WMM (802.11e) and Unscheduled Autmatic Pwer Save Delivery (UAPSD). 6.1 Cnfigure WMM n the WESM T priritize vice traffic yu can cnfigure WiFi Multimedia (WMM), which is a WiFi Alliance interperability certificatin based n the 802.11e standard. WMM autmatically defines fur classes f traffic that will be queued and priritized accrdingly. T cnfigure WMM n the Wireless Edge Services Mdule: 1. Edit the vice WLAN. 2. In Advanced Parameters, set the Access Categry t Autmatic WMM. 3. In Netwrk Setup > WLAN Setup > Edit screen, g t the WMM tab and verify that the vice VLAN is cnfigured fr WMM with fur queues: Vice, Vide, Backgrund and Best Effrt. 4. If desired, yu can mdify the parameters f these different classes f traffic: AIFSN, Arbitratin IFS Number, the default time befre cuntdwn. CW minimum (CWmin), the minimum cntentin windw. CW maximum (CWmax), the maximum cntentin windw. Transmit Ops (TXOP), the pprtunity t transmit. This is the time during which a statin that has wn the cntrl f the shared medium can retain it.

Interperability between PrCurve WESM zl and Siemens Gigaset SL75 wireless phne Use DSCP r 802.1p pririty (DSCP by default). 5. Click OK t accept Autmatic/WMM as the Access Categry. Wireless traffic is placed in the fur queues accrding t its 802.1p pririty (default) r DSCP value. Nte that fr each queue, the fur parameters are defined: AIFSN, CW minimum, CW maximum and Transmit Ops. Fr mre infrmatin n WMM cnfiguratin n the WESM, please refer t PrCurve Applicatin Nte AN- M12, Using 802.11e and WMM n the PrCurve Wireless Edge Services Mdule. 6.2 Using UAPSD n the Siemens wireless IP phne UAPSD (Unscheduled Autmatic Pwer Save Delivery) has been adpted by the WiFi Alliance, where it is knwn as WMM Pwer Save. This technlgy allws saving battery pwer and fine-tuning the pwer cnsumptin f wireless statins n WMM-enabled wireless netwrks. N special cnfiguratin fr UAPSD is necessary fr the Siemens Gigaset SL75 WLAN phne, which natively supprts UAPSD. Siemens explicitly recmmends using an access pint that supprts WMM.
