Article Title
How to Setup Cisco DHCP server to Support MITEL IP phones, No VLAN or VLAN
Publish Date
Nov-3-2004

Description/Symptoms
IP Phones fail to boot when using Cisco DHCP services.

Body/Solutions
The following is suggested programming. For detailed programming questions and technical support, contact the manufacturer.

Note: The SX-200 ICP can use Cisco DHCP server on the router or switch to provide external DHCP service.

Scenario 1: No VLAN

· The IP phones are on a dedicated voice LAN

In this example, the 200 ICP is programmed as follows:

SX-200 ICP settings:
ItemSetting
IP Address192.168.31.2
Subnet Mask255.255.255.0
Default Gateway192.168.31.1

In Form 47, select DHCP server Disabled.

Scenario 2: VLAN Support
· PCs and IP phones are running on different VLANs.
· PC can be connected to the second port on the back of IP phone. So both IP phone and PC share the same Ethernet outlet.
· All PCs use Cisco default VLAN 1. DHCP range from 192.168.38.10 to 100.
· All the IP phones use VLAN 2, DHCP range from 192.168.31.10 to 100 with priority 5.

VLAN 1: 192.168.38.0
VLAN 2: 192.168.31.0
