      "This is the MIB Module for DOCSIS-compliant cable modems
and cable-modem termination systems.

      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
- Clarified the description for
  docsDevFilterTosOrMask
- Covered the case of a non-existent row for
  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
  support the usage of RFC3413 and RFC3014
- Modified DESCRIPTION for docsDevMaxCpe";

          "An ordered list of filters or classifiers to apply to
IP traffic. Filter application is ordered by the filter
index, rather than by a best match algorithm (Note that
this implies that the filter table may have gaps in the
index values).  Packets that match no filters will have
policy 0 in the docsDevFilterPolicyTable applied to
them, if it exists.  Otherwise, Packets that match no
filters are discarded or forwarded according to the
setting of docsDevFilterIpDefault.

Any IP packet can theoretically match multiple rows of
this table.  When considering a packet, the table is
scanned in row index order (e.g., filter 10 is checked
before filter 20).  If the packet matches that filter
(which means that it matches ALL criteria for that row),
actions appropriate to docsDevFilterIpControl and
docsDevFilterPolicyId are taken.  If the packet was
discarded processing is complete.  If
docsDevFilterIpContinue is set to true, the filter
comparison continues with the next row in the table,
looking for additional matches.

If the packet matches no filter in the table, the packet
is accepted or dropped for further processing
according to the setting of docsDevFilterIpDefault.
If the packet is accepted, the actions specified by
policy group 0 (e.g., the rows in
docsDevFilterPolicyTable that have a value of 0 for
docsDevFilterPolicyId) are taken, if that policy
group exists.

Logically, this table is consulted twice during the
processing of any IP packet: once upon its acceptance
from the L2 entity, and once upon its transmission to
the L2 entity.  In actuality, for cable modems, IP
filtering is generally the only IP processing done for
transit traffic.  This means that inbound and outbound
filtering can generally be done at the same time with
one pass through the filter table.

The objects in this table are only accessible from cable
devices that are not operating in DiffServ MIB mode
(RFC 3289).  See the conformance section for details.

Note that some devices are required by other

for backward compatibility.
