        REVISION "200612200000Z" -- December 20, 2006

        DESCRIPTION

            "Second version, published as RFC 4639.

             Modifications to this MIB module since RFC 2669 include:

             - Deprecation of the docsDevFilter group in favor of the

               DiffServ MIB groups, to enable support for IPv6

               filtering and DiffServ Code Point (DSCP) marking.

             - Deprecation of the docsDevCpeGroup in favor of the

               docsDevCpeInetGroup, to enable support of IPv6.

             - Addition of various InetAddress objects to enable

               support of IPv6.

             - Deprecation of docsDevNmAccessTable in favor of SNMP

               Coexistence and SNMPv3 -- yet adding

               docsDevNmAccessTrapVersion and clarifying

               docsDevNmAccessIp for current use of this table,

             - Addition of docsDevIgmpModeControl for management and

               control of the IGMP mode of operation,

             - Addition of docsDevMaxCpe for management of the

               maxmium number of CPEs permitted access through a

               cable modem,

             - Addition of docsDevSwServerTransportProtocol, and

               modifications to docsDevSoftware object DESCRIPTIONS,

               to enable software downloads via either TFTP or HTTP,

             - Replacement of docsDevEvThrottleInhibited with

               docsDevEvThrottleThresholdExceeded to simplify

               event threshold management,

             - Modification of docsDevEvReporting to enable local

               logging to the internal volatile log, and not to the

               internal non-volatile log,

             - Modification of the compliance statement to make the

               docsDevCpe objects optional

             - Created placeholders for two OIDs in the

               docsDevFilterPolicyTable that were never used

             - Modified the DESCRIPTION of

               docsDevSwServerTransportProtocol and

               docsDevSwServerAddressType to address the

               dependence between each object

             - Added a reference to docsDevServerConfigTftpAddress

             - Clarified the scope of notifications that are covered

               by docsDevEvThrottleThreshold

             - Clarified an error condition that could occur when

               doing a SET to docsDevEvReporting

             - Defined each of the enumerated types for both

               docsDevEvLevel and docsDevEvPriority

             - Added UNITS clause to docsDevFilterLLCMatches,

               docsDevFilterIpMatches, docsDevMaxCpe,

               docsDevEvThrottleThreshold and docsDevEvCounts.

             - Added REFERENCE clause to docsDevFilterIpProtocol

             - Modified DESCRIPTION of docsDevCpeInetAddr to be

               more protocol-neutral

             - Removed the enumerated value (1) from both

               docsDevCpeInetSource and docsDevCpeSource

             - Covered additional read-write and read-create objects

               in the Security Considerations section

             - Modified the default value of docsDevNmAccessIpMask

               to be consistent with OSSI specification

             - Modified the SYNTAX of docsDevNmAccessCommunity and

               docsDevNmAccessInterfaces in the Conformance

               Statement section

             - Added SYNTAX clause to docsDevEvReporting in the

               Conformance Statement section

             - Modified SYNTAX clause of docsDevEvReporting to

               move new enumerated type to byte boundary

             - Added references to DOCSIS 2.0 specifications to

               multiple objects

             - Clarified non-persistency across reboots for

               all tables

             - Clarified functionality of docsDevSw objects as

               they relate to docsDevSwOperStatus

             - Clarified enumerated types (9) and (10) for

               docsDevServerBootState

             - Defined the state of unknown(0) for the following

               objects:  docsDevServerDhcpAddressType,

               docsDevServerTimeAddressType,

               docsDevServerConfigTftpAddressType and

               docsDevServerConfigTftpAddressType

             - Modified the value in docsDevFilterIpDaddr to be

               consistent with the SYNTAX

             - Specified which rows could be modified in an

               active row for docsDevFilterPolicyStatus

             - Defined the term 'manually' in docsDevCpeEnroll

               docsDevFilterPolicyPtr

             - Added DEFVAL clauses for multiple objects

             - Replaced docsDevNotification OBJECT IDENTIFIER

               with docsDevNotifications to address possible

               compatibility issues

             - Added support for the usage of RFC 3413 and RFC 3014

               as event notification mechanisms

             - Removed docsDevFilterPolicyObsoleteGroup

             - Added stdInterface(9) type to docsDevEvReporting to
