This document describes how ProCurve switches and Mitel IP phones interoperate to build a secure and easy-to-manage network. Both the switch and the phone rely on standard protocols:
- 802.3af, 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.
- LLDP-MED is a discovery protocol that enables switches to get some layer 2 information about a phone (such as its model, firmware, location, etc.) and automatically allocate certain network parameters (VLAN and QoS) to the phone.
- 802.1X is the most recommended authentication method for access control on the network. It is recognized as a standard, and is implemented by most IP telephony constructors. Multiple 802.1X authentication enables authentication both of a phone plugged into a switch and of a user plugged into the dual port of the phone, while assigning them different profiles (VLAN, QoS, bandwidth).

The platform 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).
- Mitel Networks 5220 IP Phone (Dual Mode).
- 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 or using DHCP.
Configuring QoS from the phone’s web interface:
- To access Mitel 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: 5220
- You can assign values to the 802.1p and/or DSCP fields.
Configuring QoS via DHCP options assignment: Configure the following options on the DHCP server:
- 133 - (specific) Priority (32 bit) 0x6
- 134 - (specific) DSCP value 0 to 63 (32 bit) 0x2e (This hexadecimal value is equivalent to 46 decimal.)
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:
To view which DSCP and QoS values are configured:

Firmware versions of the switches used for this application note are as follows:
- K.13.09 for the ProCurve ProVision switches (5406zl, 3500yl, 8212zl)
- R.11.07 for the ProCurve Switch 2610-PWR
Firmware version of the Mitel phone 5220 is SIP 6.0.0.19. Release 6 is recommended because this release ensures the Mitel phone can support 802.1X and LLDP-MED capabilities. To follow the procedures in this application note, you will need to upgrade your Mitel phone to this version.
7.1 Download firmware and upgrade the Mitel phone
To upgrade the Mitel phone’s firmware, you need to copy and extract firmware files to a TFTP server. Note that Mitel firmware is available from: http://sipdnld.mitel.com/
To upgrade the Mitel phone’s firmware:
- On the Mitel phone, confirm your firmware version by holding down the volume up key to get into configuration mode, then navigate to “View Version Info”. Look for the “main load version”. (This procedure assumes your firmware is at release 3.x. If you are running release 4.x, start with the latest release 5 build on the TFTP server instead of the release 4 build.)
- Set up a TFTP server. If one is not readily available there are many available as shareware or freeware on the Internet. Make sure that you write down the IP address of where you have the TFTP server running.
- Unzip the latest release 4 firmware build into the TFTP root of your TFTP server.
- Power the phone while holding down the * and 7 key to switch to SIP mode. Hold down the keys until you see the change confirmed on the phone display.
- Assuming that the phones are using DHCP, power the phone while pressing the volume up arrow. You are now in the phone’s configuration mode.
- Navigate through the menus until you see a place to change the TFTP server address (Network parameters, modify static settings). Enter the IP address of your TFTP server from step 2 above.
- While the phone is booting you will see an option to upgrade via TFTP. Select yes. (You may have to press * for yes depending on the phone). You should then see the firmware upgrading. When this is complete, you see the date and time appear on the phone.
- Once the firmware upgrade is complete, delete build 4 from the TFTP root.
- Then unzip the latest release 5 build into the TFTP root, and repeat steps 5, 6, 7, and 8. Steps 5 and 6 are very important, because the network setting returns to the factory default after an update.
- Once the release 5 firmware upgrade is complete, repeat the steps again for release 6.
7.2 Upgrading through the Mitel 3300 ICP
Another possibility for upgrading is through the Mitel 3300 ICP IPBX, which must have at least release 7.0 ( latest is 8.0 UR3) to ensure LLDP-MED and 802.1X support.
