    --  Abstract
    --
    --  This memo defines management objects which are required to support
    --  Cabletron's implementation of the Dynamic Host Configuration Protocol.
    --  This MIB supports in part RFC1541 and RFC1533.  Specifically, it enables
    --  a device to be configured as a DHCP server, and allows a limited number
    --  of DHCP Options.
 
    --  Structure of MIB
    --
    --  Objects, in this MIB, are arranged into groups.  Each group is organized
    --  as a set of related objects and is described below.
 
    --  The ctDhcpServerStats Group
    --
    --  This group enables DHCP globally, and displays statistics relating
    --  to the overall DHCP entity.  It also allows abandoned addresses to
    --  be recovered.

    --  The ctDhcpInterfaceConfig Group
    --
    --  This group contains information describing the assignment
    --  of interfaces on this device to perform DHCP server functions. 
    --  It allows customization of the server on an interface basis.

    --  The ctDhcpClientStatusTable Group
    --
    --  This group contains information describing some identifying
    --  characteristics which are collected for ACTIVE leases.  The data 
    --  are deleted when the lease expires.
