15.1.2 Configuring the Vendor Class Identifier

The DHCP Vendor Class table lets you configure up to 10 Vendor Class Identifier (VCI)

names (DHCP Option 60). When the table is configured, the device's DHCP server

responds only to DHCPDiscover requests that contain Option 60 and that match one of the

DHCP VCIs configured in the table. If you have not configured any entries in the table, the

DHCP server responds to all DHCPDiscover requests, regardless of the VCI.

The VCI is a string that identifies the vendor and functionality of a DHCP client to the

DHCP server. For example, Option 60 can show the unique type of hardware (e.g.,

"AudioCodes 440HD IP Phone") or firmware of the DHCP client. The DHCP server can

then differentiate between DHCP clients and process their requests accordingly.

The following procedure describes how to configure the DHCP VCIs through the Web

interface. You can also configure it through ini file (DhcpVendorClass) or CLI (configure

voip > dhcp vendor-class).

To configure DHCP Vendor Class Identifiers:

Open the DHCP Servers table (Configuration tab > VoIP menu > Services > DHCP

In the table, select the row of the desired DHCP server for which you want to configure

VCIs, and then click the DHCP Vendor Class Table link, located below the table; the

DHCP Vendor Class table opens.

Click Add; the following dialog box appears:
