Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. MIB objects are generally accessed through the Simple Network Management Protocol (SNMP). Objects in the MIB are defined using the mechanisms defined in the Structure of Management Information (SMI). This memo specifies a MIB module that is compliant to the SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580].
The terms in this document are derived either from normal cable system usage, or from the documents associated with the Data-Over- Cable Service Interface Specification (DOCSIS) process.
Originally "Community Antenna Television", now used to refer to any cable or hybrid fiber and cable system used to deliver video signals to a community.
A CM acts as a "slave" station in a DOCSIS-compliant cable data system.
A generic term covering a cable bridge or cable router in a head-end. A CMTS acts as the master station in a DOCSIS-compliant cable data system. It is the only station that transmits downstream, and it controls the scheduling of upstream transmissions by its associated CMs.
A term referring to the ITU-T Recommendation J.112 [ITU-T_J.112], Annex B, standard for cable modem systems. [RFI1.0] [RFI1.1] [RFI2.0]

Protocol used for network access to Management Information Base (MIB) objects. The three most commonly used versions are Version 1 (SNMPv1), Version 2 (SNMPv2c), and Version 3 (SNMPv3).
The direction from the subscriber towards the head-end.
This MIB module provides a set of objects required for the management of DOCSIS-compliant Cable Modems (CM) and Cable Modem Termination Systems (CMTS). The specification is derived from the DOCSIS Radio Frequency Interface specification [RFI1.0]. Please note that the DOCSIS 1.0 standard only required that Cable Modems implement SNMPv1 and to process Internet Protocol Version 4 (IPv4) customer traffic. Design choices in the original version of this MIB module reflected those requirements. DOCSIS 1.1 [RFI1.1] and DOCSIS 2.0 [RFI2.0] require support for SNMPv3, as well as for SNMPv1 and SNMPv2c, and the changes in this MIB module over the previous proposed standard version reflect those additional requirements.
Future versions of DOCSIS, starting with DOCSIS 3.0 [MULPI3.0], are expected to require support for the Internet Protocol Version 6 (IPv6) as both a Customer Premise Equipment (CPE) protocol and one supported by the network elements of the DOCSIS CMTS/CM system.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119].
This MIB module is structured into seven components. A component contains one or more MIB groups related by deprecation or logical extension.
This MIB module IMPORTs definitions normatively from the following MIB modules, beyond [RFC2578], [RFC2579], and [RFC2580]: INET- ADDRESS-MIB [RFC4001], SNMP-FRAMEWORK-MIB [RFC3411], IF-MIB [RFC2863], RMON2-MIB [RFC4502], and DIFFSERV-MIB [RFC3289].
This MIB module also includes DESCRIPTION and REFERENCE clauses that normatively refer to [RFC868], [RFC3617], [RFI1.0], [RFI1.1], [RFI2.0], [OSSI1.1], and [OSSI2.0].
Most of the tables in this MIB module (e.g., docsDevNmAccessTable, docsDevFilterLLCTable) are specified not to let objects persist across reboots.
The expectation (and current operational practice) is that upon reboot, these tables are cleared and repopulated from the DOCSIS configuration file supplied by the cable operator. This approach enables a cable modem to adapt to the current cable operator's environment, which in turn enables cable modem portability across different cable operators.
A notable exception to the persistence model is docsDevEventTable, since it is useful to maintain a record of events across reboots for debugging purposes.
Please note that the compliance statements in this version of the MIB module require support only for IPv4 addresses. That is because the current versions of the DOCSIS protocols (1.0, 1.1, and 2.0) are not IPv6 capable. Although support for IPv6 will require changes to the DOCSIS protocols, it is expected that the only changes needed to the MIB module itself will be the addition of new compliance statements that mandate support for IPv6 addresses.
The Cable Modem software upgrade process is documented in [RFI1.0]. From a network management station, the operator
Although DOCSIS only specifies the implementation of the TFTP
protocol [RFC1350] for file transfers, other functional entities
embedded within the cable device (particularly a PacketCable
Multimedia Terminal Adapter [MTA-PROV]) specify the optional
implementation of the Hyper Text Transfer Protocol (HTTP) [RFC1945]
and [RFC2616] for file transfers. The value of the
docsDevSwServerTransportProtocol object determines which protocol is
used for SNMP-initiated software upgrade.
One reason for the SNMP-initiated upgrade is to allow loading of a temporary software image (e.g., special diagnostic software) that differs from the software normally used on that device without changing the provisioning database.
Note that software upgrades should not be accepted blindly by the cable device. The cable device may refuse an upgrade if
A cable device that implements the code verification mechanisms of [BPIPLUS] verifies the source and integrity of the downloaded image by validating one or more Code Verification Signatures that are bundled within the software upgrade.
This MIB module provides control facilities for reporting events through syslog [RFC3164], notifications (traps and informs), and non-volatile logging. Additional controls allow the agent to use the SNMP Notification MIB [RFC3413] and Notification Log MIB [RFC3014] for event notification.
The conventions for event reporting are outside the scope of this document. The definition and coding of common DOCSIS notifications can be found in [RFC4547].
The CM and CMTS MUST provide support for notification message throttling as described below. The network operator can employ notification rate throttling or notification limiting by manipulating the appropriate MIB variables.
Network operators may employ either of two rate control methods. In the first method, the device ceases to send notifications when the rate exceeds the specified maximum message rate. It resumes sending notifications only if reactivated by a network management station request.
In the second method, the device resumes sending notifications when the rate falls below the specified maximum message rate.
The network operator configures the specified maximum message rate by setting the measurement interval (in seconds), and the maximum number of notifications to be transmitted within the measurement interval. The operator can query the operational throttling state (to determine whether notifications are enabled or blocked by throttling) of the device, as well as query and set the administrative throttling state (to manage the rate control method) of the device.
Network operators may wish to limit the number of notifications sent by a device over a specified time period. The device ceases to send notifications when the number of notifications exceeds the specified threshold. It resumes sending notifications only when the measurement interval has passed.
The network operator defines the maximum number of notifications he
is willing to handle and sets the measurement interval to a large
number (in hundredths of a second). For this case, the
administrative throttling state is set to stop at a threshold that is
the maximum number of notifications.
See "Techniques for Managing Asynchronously Generated Alerts" [RFC1224] for additional technical motivations.
The Cable Device MIB provides objects for both Link Layer Control (LLC) and IP protocol filters. The LLC protocol filter entries can be used to limit CM forwarding to a restricted set of network-layer protocols (such as IP, Internetwork Packet Exchange (IPX), Network Basic Input/Output System (NetBIOS), and Appletalk).
The IP protocol filter entries can be used to restrict upstream or downstream traffic according to source and destination IP addresses, transport-layer protocols (such as Transport Control Protocol (TCP), User Datagram Protocol (UDP), and Internet Control Message Protocol (ICMP)), and source and destination TCP/UDP port numbers.
In general, a cable modem applies filters (or, more properly, classifiers) in an order appropriate to the layering model. Specifically, the inbound MAC (or LLC) layer filters are applied first, then the "special" filters, then the IP layer inbound filters, then the IP layer outbound filters, and then any final LLC outbound filters.

The inbound LLC (or MAC or level-2) filters are contained in the docsDevFilterLLCTable and are applied to level-2 frames entering the cable modem from either the RF MAC interface or from one of the CPE interfaces (physical or logical). These filters are used to prohibit the processing and forwarding of certain types of level-2 traffic that may be disruptive to the network. The filters, as currently specified, can be set to cause the modem either to drop frames that match at least one filter, or to process a frame that matches at least one filter. Some examples of possible configurations would be to permit only IP (and ARP) traffic, or to drop NetBIOS traffic.
Special filters are applied after the packet is accepted from the MAC layer by the IP module, but before any other processing is done. They are filters that apply only to a very specific class of traffic.
IP spoofing filters are applied to packets entering the modem from one of the CPE interfaces and are intended to prevent a subscriber from stealing or misusing IP addresses that were not assigned to the subscriber. If the filters are active (enabled), the source address of the IP packet must match at least one IP address in one of these two tables (docsDevCpeTable or docsDevCpeInetTable), or it is discarded without further processing.
To prevent potential implementation ambiguity, the device consults the docsDevCpeTable for the IP packet source address before consulting the docsDevCpeInetTable.
The table can be automatically populated where the first N different IP addresses seen from the CPE side of the cable modem are used to populate the table automatically. The spoofing filters are specified in the docsDevCpeTable and the docsDevCpeInetTable, and the policy for automatically creating filters in those tables is controlled by docsDevCpeEnroll and docsDevMaxCpe, as well as by the network management agent.
Similar IP spoofing filter controls are defined for CMTS
implementation in the Subscriber Management MIB [RFC4036].
The SNMP access filters are applied to SNMP packets entering from any interface and destined for the cable modem. If the packets enter from a CPE interface, the SNMP filters are applied after the IP spoofing filters. The filters only apply to SNMPv1 or SNMPv2c traffic and are not consulted for SNMPv3 traffic (and need not be implemented by a v3-only agent). SNMPv3 access control is specified in the User Security Model MIB, in [RFC3414].
With the completion of the SNMP coexistence document, RFC 3584 [RFC3584], docsDevNmAccess table has been deprecated in this version of the MIB. See the body of the MIB for the description of how agents should handle the interaction between RFC 3584 MIBs and this MIB.
The IP Filtering table acts as a classifier table. Each row in the table describes a template against which IP packets are compared. The template includes source and destination addresses (and their associated masks), upper level protocol (e.g., TCP, UDP), source and destination port ranges, and Terms of Service (ToS) values. A row also contains interface and traffic direction match values that have to be considered in combination. All columns of a particular row must match the appropriate fields in the packet and must match the interface and direction items for the packet to result in a match to the packet.
When classifying a packet, each table is scanned, beginning with the lowest number filter. If the agent finds a match, it applies the group of policies specified. If the matched filter has the continue bit set, the agent continues the scan possibly matching additional filters and applying additional policies. For example, this allows the agent to take one set of actions for the 24.0.16/255.255.255.0 group and one set of actions for telnet packets to/from 24.0.16.30, and these sets of actions may not be mutually exclusive.
Once a packet is matched, one of three actions happen according to the setting of docsDevFilterIpControl in the row. The packet may be dropped, in which case no further processing is required. The packet may be accepted, and processing of the packet continues. Lastly, the packet may have a set of policy actions applied to it. If docsDevFilterIpContinue is set to true, scanning of the table continues and additional matches may result.
When a packet matches and docsDevFilterIpControl in the filter
matched is set to 'policy', the value of docsDevFilterIpPolicyId is
used as a selector into the docsDevFilterPolicyTable. The first
level of indirection may result in zero or more actions being taken
according to the match. The docsDevFilterPolicyTable is scanned in
row order, and all rows where docsDevFilterPolicyId equals
docsDevFilterIpPolicyId have the action specified by the
docsDevFilterPolicyValue 'executed'.
For an example of the use of these IP Filtering MIB tables, see [RFC2669].
The IP Filtering table and related tables have been deprecated in this version of the MIB in favor of the Data Path, Classifier, and Action tables from the Differentiated Services MIB [RFC3289]. See the body of the MIB for the description of how agents should handle the interaction between RFC 3289 MIBs and this MIB module.
Lastly, any outbound LLC filters are applied to the packet just prior to its being emitted on the appropriate interface. This MIB module does not specify any outbound LLC filters, but section 3 of the DOCSIS Quality of Service (QoS) MIB, [RFC4323], includes outbound LLC filtering requirements.

DESCRIPTION

docsDevFilterIpTable OBJECT-TYPE
SYNTAX SEQUENCE OF DocsDevFilterIpEntry
MAX-ACCESS not-accessible
STATUS deprecated
DESCRIPTION
"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 specifications (e.g., the DOCSIS OSSIv1.1 specification) to support the legacy SNMPv1/v2c docsDevFilter mode for backward compatibility.
Table entries MUST NOT persist across reboots for any device.
This table is deprecated. Instead, use the DiffServ MIB from RFC 3289."

This says that a packet that matches a filter with policy id 1 first has TOS policy 1 applied (which might set the TOS bits to enable a higher priority) and next has the IPSEC policy 3 applied (which may result in the packets being dumped into a secure VPN to a remote encryptor).
