           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

                - Added DEFVAL clauses for multiple objects
                - Replaced docsDevNotification OBJECT IDENTIFIER
                  with docsDevNotifications to address possible
                  compatibility issues

Top      Up      ToC       Page 17 
                - Added support for the usage of RFC 3413 and RFC 3014
                  as event notification mechanisms
                - Removed docsDevFilterPolicyObsoleteGroup
                - Added stdInterface(9) type to docsDevEvReporting to

                completed the Registration exchange.

                If disabled(2), then the device was administratively
                disabled, possibly by being refused network access in
                the configuration file.

                If waitingForDhcpOffer(3), then a Dynamic Host
                Configuration Protocol (DHCP) Discover has been
                transmitted, and no offer has yet been received.

                If waitingForDhcpResponse(4), then a DHCP Request has
                been transmitted, and no response has yet been received.

                If waitingForTimeServer(5), then a Time Request has been
                transmitted, and no response has yet been received.

Top      Up      ToC       Page 29 
                If waitingForTftp(6), then a request to the TFTP
                parameter server has been made, and no response
                received.

                If refusedByCmts(7), then the Registration
                Request/Response exchange with the CMTS failed.

                If forwardingDenied(8), then the registration process
                was completed, but the network access option in the
                received configuration file prohibits forwarding.

                If other(9), then the registration process reached a
                point that does not fall into one of the above
                categories.

                If unknown(10), then the device has not yet begun the
                registration process or is in some other indeterminate
                state."
