Initial Configuration; Creating A Dhcp Scope For The Ip Telephones - Avaya Application Solutions Deployment Manual

Initial configuration

The Windows NT 4.0 DHCP server configuration involves setting up a scope for the IP
Telephone. A DHCP scope is essentially a grouping of IP devices (in this case IP Telephones)
running the DHCP client service in a subnet. The scope is used to define parameters for each
subnet. Each scope has the following properties:
A unique subnet mask used to determine the subnet related to a given IP address.
A scope name assigned by the administrator when the scope is created.
Lease duration values to be assigned to DHCP clients with dynamic addresses.
In addition, the DHCP server can assign configuration parameters to a client, and these can be
specified for each individual DHCP scope. Setting up of the Windows NT 4.0 DHCP server,
requires these steps:
1.

Creating a DHCP scope for the IP Telephones

2. Editing custom options
3. Adding the DHCP option
4. Activating the leases
Creating a DHCP scope for the IP Telephones
Use the following procedure to create a DHCP scope for the IP Telephones:
1. Select Start->Programs->Admin Tools->DHCP Manager.
2. Expand Local Machine in the DHCP Servers window by double clicking on it until the +
sign changes to a - sign.
3. Select Scope->Create.
4. Define the range of IP addresses used by the IP Telephones.
The Start Address should be the first IP address to be used for the IP Telephones.
The End Address should be the last IP address to be used for the IP Telephones.
Subnet Mask should be set to the value assigned by the network administrator.
5. Perform these steps to exclude any IP addresses that you do not want to be assigned to IP
Telephones within the range specified by the Start and End Addresses.
a. Enter the first IP address in the range that you would like to exclude in the Start Address
field under Exclusion Range.
b. Enter the last IP address in the range that you would like to exclude in the End Address
field under Exclusion Range.
c. Click the Add button.
d. Repeat steps a. through c. for each IP address range that you would like to exclude.
