Address Manager Administration Guide

Product name
BlueCat Integrity

Match classes in Address Manager (also known as classes in ISC DHCP and as user and vendor classes in Microsoft DHCP) allow you to restrict address allocation and assign options to clients that match specified criteria.

For example, using a match class, you could assign a specific DHCP lease length to clients that match a MAC address pattern or clients that are configured to send a specific identifier. A DHCP client becomes a member of a class when it matches the specified criteria.

Address Manager provides seven match statement options:
  • Match Hardware
  • Match DHCP Client Identifier
  • Match DHCP Vendor Identifier
  • Match Agent Circuit Identifier
  • Match Agent Remote Identifier
  • Custom Match
  • Custom Match If
Match statements define the parameters for the match. All match statement options, except for Custom Match, and Custom Match If, accept two variables:
  • Match Offset—refers to the point where the match should begin.
  • Match Length—refers to the number of characters to match.
