Cisco Discovery Protocol (CDP)

Prior to Release 5.1 the Mitel IP devices discovered VLAN information
dynamically through DHCP. With Release 5.1, Mitel IP device messages
are now compatible with Cisco Discovery Protocol (CDP) for the purpose
of port duplex and speed settings, port MAC identification and Auxiliary
VLAN assignment. If your network uses Cisco Layer 2 switches, you may
configure your L2 ports as Access ports and use the auxiliary VLAN to set
the voice VLAN, allowing both phones and PC to share the same network
port. For more information on configuring your network, refer to the
3300 ICP Engineering Guidelines, available at http://edocs.mitel.com.
The IP devices understand CDP messages for the following:
• Advertising their in-line power consumption
• Discovering the voice VLAN setting from the Cisco L2 switch
• Advertising their duplex setting, platform, and software release for the
"show cdp neighbor" command on the L2 console.
To obtain VLAN information via CDP:
• Set the network part as Access
• Enter the Voice VLAN, or the Auxiliary_VLAN setting
• Enter the data or default VLAN into the Native_VLAN setting
• In DHCP there is no requirement to enter VLAN or Priority into the
default/data VLAN
• Set the Priority field to "6" in the voice VLAN scope of DHCP.
