DHCP Options

Parameter

Description

Default Value

ID

For a Standard (Publicly Defined) option, users can select the value.

Reserve option 43 or 125 (the default) for Mitel IP Phones.

Options 224 to 254 are reserved for site-specific options which users define themselves.

See below for a list of all DHCP Options numbers.

Blank

Name

The name of the option. User-defined names can be up to 32 characters long. If no name is entered when an option is added or edited, the standard name (Router, Mask, etc.) will be inserted if known. For options 43 and 125, the name inserted is "Vendor Specific". For options 224-254, the name is "Site-Specific." Unknown names display as "User Defined."

Blank

Format

When an option is added or edited, users can select the format of the value for this option from the following: System Default, IP Address, ASCII String (set by default), Numeric, or Octet String.

Select "IP Address" for any IP Console in a cluster.

System Default

Value

When a site-specific option is added or edited, enter the value of the options.

For an IP Console in a cluster, enter the IP Address of the 3300 ICP that controls the device.

• Note: Do not enter leading zeros in the IP Address.

Blank

Scope

Select the level that the option applies to from Global, Subnet, or Range. Global is the default.

For an IP Console in a cluster, select "Static<device name>< subnet>".

The following fields display when adding options:

Option Type

Select Mitel to create Option 125, the default option used to configure Mitel IP Phones. To create a different option, select Other.

Other

Standard Option

This field displays when Option Type is set to Other. Select the option you want to create from the drop-down list.

Select an Option

ID

Displays either the option number selected from the Standard Option list or 125 if the Option Type is Mitel.

The string is automatically generated from values entered in the Mitel Tags section of the form. Using the form guarantees a correctly formatted string. See Rules for creating Options 43 and 125 for information on how to create the string from scratch.
