1. Abstract

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   In particular, it defines a basic set of managed objects for SNMP-
   based management of a DVB Interactive Network Adapter device.

   The DVB interaction channel for Cable TV distribution systems are
   specified in the ES 200 800 [ES200800]

   This memo specifies a MIB module in a manner that is compliant to the
   SNMP SMIv2 [RFC2578][RFC2579][RFC2580]. The set of objects is
   consistent with the SNMP framework and existing SNMP standards.

   This memo is a product of the DVB RCCL workgroup, which has been
   adopted as a work item of the IPCDN WG.  Comments are solicited and
   should be addressed to the author.


   2. The SNMP Management Framework

   The SNMP Management Framework presently consists of five major
   components:

   o   An overall architecture, described in RFC 2571 [RFC2571].

                       DVB Cable INA Device MIB               Feb 2001


   o   Mechanisms for describing and naming objects and events for the
       purpose of management.  The first version of this Structure of
       Management Information (SMI) is called SMIv1 and described in
       STD 16, RFC 1155 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC
       1215 [RFC1215].  The second version, called SMIv2, is described
       in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and
       STD 58, RFC 2580 [RFC2580].

   o   Message protocols for transferring management information.  The
       first version of the SNMP message protocol is called SNMPv1 and
       described in STD 15, RFC 1157 [RFC1157].  A second version of
       the SNMP message protocol, which is not an Internet standards
       track protocol, is called SNMPv2c and described in RFC 1901
       [RFC1901] and RFC 1906 [RFC1906].  The third version of the
       message protocol is called SNMPv3 and described in RFC 1906
       [RFC1906], RFC 2572 [RFC2572] and RFC 2574 [RFC2574].

   o   Protocol operations for accessing management information.  The
       first set of protocol operations and associated PDU formats is
       described in STD 15, RFC 1157 [RFC1157].  A second set of
       protocol operations and associated PDU formats is described in
       RFC 1905 [RFC1905].

   o   A set of fundamental applications described in RFC 2573
       [RFC2573] and the view-based access control mechanism described
       in RFC 2575 [RFC2575].

   A more detailed introduction to the current SNMP Management Framework
   can be found in RFC 2570 [RFC2570].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  Objects in the MIB are
   defined using the mechanisms defined in the SMI.

   This memo specifies a MIB module that is compliant to the SMIv2.  A
   MIB conforming to the SMIv1 can be produced through the appropriate
   translations.  The resulting translated MIB must be semantically
   equivalent, except where objects or events are omitted because no
   translation is possible (use of Counter64).  Some machine readable
   information in SMIv2 will be converted into textual descriptions in
   SMIv1 during the translation process.  However, this loss of machine
   readable information is not considered to change the semantics of the
   MIB.

4. Overview

   This MIB provides a set of objects required for the management of a
   DVB INA.

   The MIB is intended for devices using IPv4 addresses. All IP
   addresses are however specified as described in RFC 2851 [RFC2851] to
   aid future migration to IPv6.

                       DVB Cable INA Device MIB               Feb 2001



   4.1   Structure of the MIB

   The MIB is structured in 9 groups. All groups are optional to
   implement in order to be compliant. The reason to make all groups
   optional is that the MIB structure does not fit all INA
   configurations well û especially integrated router and INA systems.

   o   Device group.

   o   Network management access group.

   o   SW group.

   o   DHCP group.

   o   Event group.

   o   IP Filter group.

   o   Ethernet Filter group.

   o   NIU Error group.

   o   NIU IP group.


   4.1.1   Device group

   The Device group contains object for general device control for the
   INA. The version of the MIB is also found here.

   4.1.2   Network Management access group

   The Network Management access group specifies addresses, password and
   access rights for management stations that are allowed to access the
   INA.

   4.1.3   SW group

   The SW group contain objects for control of up- and download of
   software to the INA. A table for administration of several software
   images is found.

   4.1.4   DHCP group

   The DHCP group contains objects for specification of the DHCP servers
   used by the INA, the NIUs or the CPE. Both primary and secondary DHCP
   servers can be specified.

                       DVB Cable INA Device MIB               Feb 2001

   4.1.5   Event group

   The Event group contain a syslog server address and object for
   limiting the number of syslog messages and traps.
   Trap throttling can be done with maintainBelowThreshold or
   stopAtThreshold in which case the management station must reset the
   threshold state in order to restart the trap sending.
   A table that controls the action taken depending on the error
   severity is found.
   Finally controls for an error log is found. The error numbers will be
   vendor specific.
   Traps are not defined in this MIB, but can be vendor specific.

   4.1.6   IP Filter group

   The IP filter group specifies objects for making an IP filter
   function.

   4.1.6.1   IP Filter rows

   The filter can be connected to the MAC interface or any other network
   interface in inbound, outbound or both directions.
   The filter action can be accept, discard or tosmap. Furthermore there
   is a continue flag.
   When an IP packet enters the filter, the packet is tested against the
   rows in the filter in increasing order starting with the lowest
   numbered filter row.
   If there is a match and the action is discard, then the packet is
   discarded no matter what the continue flag is or what other filter
   rows the packet has matched.
   If the action is accept, then the continue flag is tested. If
   continue is cleared, then the packet is simply accepted and no more
   filter rows are tested. If the continue flag is set, the packet is
   tested against the next filter row.
   If the action is tosmap, then the TOS in the IP packet is changed
   according to the specified row in the TOS map table. If no matching
   row is found in the TOS map table or if the TOS map index in the
   filter row is 0, then no TOS mapping is done. Apart from changing the
   TOS the tosmap action is treated as the accept action.

   If all filter rows has been tested and there has been at least one
   accept or tosmap match, the packet is accepted. If there has been no
   match at all, the packet is discarded. This means that if the filter
   is enabled at least one filter row that can accept packets must exist
   in order to let anything at all through.

   If the TOS in the IP packet is changed by a TOS map action, then the
   test in the next filter rows must use the new TOS value.

   4.1.6.2   IP Filter operation

   The IP filter enable mode can be enable in which case the IP filter
   works as explained above.


Pedersen         Informational - Expires August 2001                5

                       DVB Cable INA Device MIB               Feb 2001

   When the IP filter enable mode is set to countHits, the filter works
   as explained above, except that the IP packets are never discarded,
   but filter row hits are just counted. If the filter action is
   discard, then no more rows are tested just as in normal operation.

   If the IP filter enable mode is disabled, all packets are let
   through.

   In the enable mode enableAuto, the IP filter works as normal except
   it is automatically populated with anti-spoofing rows. Each time an
   IP address is assigned to a NIU or a CPE with DHCP or BOOTP the INA
   must sniff the assigned IP address and make corresponding filter
   rows. A filter row on the MAC interface must be set to accept the IP
   address as source address and another filter row must be set to
   accept the IP address as destination address. Both filter rows must
   have the continue flag set and dvbInaIpFilterAssigned by must be
   dhcp.
   The filter rows are made with the lowest free filter index at the
   time of creation. This mean that the automatically generated filter
   rows can be intermixed with the static and management generated ones.
   To ensure the automatically generated filter rows always is applied
   first, the management generated rows must start with a sufficiently
   high filter index.
   The automatically generated filter rows do not need to be persistent
   across an INA restart. If the INA restarts then the a new DHCP or
   BOOTP request should be send from the NIU or CPE to renew the entries
   in the IP filter. The automatically generated filter rows should
   automatically timeout when the DHCP lease times out unless the
   management system has changed dvbInaIpFilterAssigned to static.
   Automatically created filter rows can only be deleted or changed to
   static by the management system.

   For filter rows created by the management system it should only be
   possible to set dvbInaIpFilterAssigned to snmp.


   4.1.7   Ethernet Filter group

   The Ethernet filter group specifies objects for making a filter
   function on the link layer level.

   The filter is applied before the IP filter and is only active on the
   input.

   The filter enable mode can be enable, disable or countHits. In the
   last case filter matches are counted, but all packets are always let
   through.

   When an Ethernet packet enters the filter, the packet is tested
   against the rows in the filter in increasing order starting with the
   lowest numbered filter row.

                       DVB Cable INA Device MIB               Feb 2001

   If the packet match the action is checked. If the action is discard,
   then the packet is discarded. If the action is accept, the packet is
   accepted. In both cases there is no further testing.

   The dvbInaEthFilterEtherType specifies the Ethernet encapsulation the
   filter row applies to. In the case ethernet2 Ethernet version2
   framing is matched and the protocol value must match the 2 byte type
   field with offset 12. In the case snap the IEEE 802.3 SNAP format is
   matched and the protocol value must match the 2 byte type field with
   offset 20. In the case llc the IEEE 802.2 LLC format is matched and
   the protocol value must match the 1 byte DSAP field with offset 14.

   If the packet does not match any filter rows, the packet is let
   through.


   4.1.8   NIU Error group

   The NIU error group specifies objects for reading error reports for
   the recently failed NIUs and for control of the error table.

   The error parameter code and error parameter value refers to the
   values in the Status Response Message specified in ES 200 800
   [ES200800]


   4.1.9   NIU IP group

   The NIU IP group specifies object for control of NIU IP addresses and
   subnets. Also the addresses of the primary and secondary DHCP server
   to be used by the NIU can be specified.

   Please note that it is compliant to implement all the configuration
   objects as read-only.

   and performance of the DVB cable system. The access to changing the
   operation should be secured.
