This document shows how ProCurve switches and the Aastra NexSpan IP Terminal or NexSpan 91xx SIP phones
interoperate to build a secure and easy-to-manage network. Both rely on standard protocols:
- 802.3af, the standard for Power-over-Ethernet (PoE), enables the switch to allocate up to 15.4W of power per port.
- Quality-of-Service (QoS) mechanisms enable the network to give voice flow—which is sensitive to delay, jitter and packet loss—priority over the data traffic, to guarantee that the communications will continue in case of congestion.
- MAC authentication of the phone provides network access control.

The platform referenced in this application note contains:
- One or more servers with the following services: Active Directory, DHCP, DNS, Certificate Authority, IAS.
- Latest versions of ProCurve Manager Plus (PCM+) and Identity-Driven Manager (IDM).
- Aastra NeXspan i760 IP Terminal or Aastra NexSpan 9133i SIP phone.
- A ProVision Switch 3500yl or 2610-PWR with the latest firmware version. A similar configuration can also be used with a ProCurve 5400zl series switch or a 8212zl series switch. The configuration commands are identical for these products and the 3500yl.
- A client laptop that can be plugged into the phone dual port for multiple authentication tests or used as a network analyzer (e.g., Wireshark)

This section explains how to configure Quality of Service parameters.
4.1 Configure QoS on the phone
Quality of Service parameters can be configured on the phone using the phone’s web interface.
To configure QoS on the Aastra phone:
- To access Aastra phone web interface, use a web browser and go to the phone’s URL:
http://<phone-ip-address>
- By default the login credentials are:
- Username: admin
- Password: 22222
- From the Network Settings menu, you can set DSCP values for the different voice and signalization protocols, including SIP, RTP, and RTCP:

4.2 Configure QoS on the switches The recommended method is to have a dedicated VLAN for voice and configure the QoS parameters for the VLAN.
The L2 and DSCP policy advertised are based on the actual QoS configuration for the voice VLAN. By default these
values are:
- L2 priority 6
- DSCP 46, which corresponds to the Expedited Forwarding (EF) class
To modify the 802.1p or DSCP values:
