-- ********************************************************************* -- CISCO-IETF-DHCP-SERVER-MIB.my : Cisco-ized version of the Dynamic -- Host Configuration Protocol for IPv4 (DHCPv4) Server MIB. -- -- March 2004, Mike Chidzik -- -- Copyright (c) 2004 by cisco Systems, Inc. -- All rights reserved. -- ********************************************************************* -- This MIB module is based on the Internet Draft -- . In terms of object syntax and -- semantics, the content of this Cisco MIB is the same as -- the corresponding Internet Draft revision. This Cisco MIB was -- created due to the "subject to change" nature of Internet Drafts. -- This Cisco MIB may later be deprecated, and the stable RFC, which -- may replace the Internet Draft, may be implemented in its place. -- Caution. This MIB is temporary and experimental. In the future it -- will be removed from products, perhaps with short notice, in favor -- of more standard or generic MIBs. Application developers should not -- depend on long-term access to this MIB. -- Note: This MIB is a subset of the objects contained in the -- Internet Draft. The comparison of this MIB and the Internet Draft -- is outlined in the below: -- Internet Draft CISCO-IETF-DHCP-SERVER-MIB -- ~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~ -- dhcpv4ServerObjects cDhcpv4SrvObjects -- bootpCounterObjects cBootpCounterObjects -- dhcpv4CounterObjects cDhcpv4CounterObjects - -- (excluding dhcpv4CountForcedRenews) -- dhcpv4ServerSharedNetObjects not contained -- dhcpv4ServerSubnetObjects not contained -- dhcpv4ServerRangeObjects not contained -- dhcpv4ServerClientObjects not contained -- dhcpv4ServerNotifyObjectsGroup not contained -- Reasons why some of the objects of the Internet Draft were not -- included in this MIB are listed here: -- -- dhcpv4ServerClientObjects is an 'optional list of addresses' -- as declared in the DESCRIPTION of this OBJECT-TYPE and since this is -- an Internet Draft is subject to more changes it seemed best to -- include/implement this later or wait till the draft becomes -- a standard. -- -- No notifications are being used from this draft at this time. All -- of the objects in dhcpv4ServerSharedNetObjects have MAX-ACCESS of -- not-accessible. Most of the objects in dhcpv4ServerSubnetObjects -- have a MAX-ACCESS of not-accessible. The exception being -- dhcpv4ServerSubnetMask and dhcpv4ServerSubnetSharedNetworkName and -- they provides limited value to include. -- -- The intent of this MIB is to implement a small useful subset of the -- objects of the Internet Draft - the statistics - and to gauge the -- response of the network management users to see the best way to -- extend this MIB.
