Description: MIB for DVB cable Network Interface Unit (NIU) device management, covering configuration, addressing, and operational status for DVB/DAVIC cable subscriber units
Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is DVB-CABLE-NIU-MIB?
DVB-CABLE-NIU-MIB is a vendor-neutral DVB/DAVIC standards MIB for the Network Interface Unit (NIU), the cable modem-like subscriber terminal defined by the EuroModem specification for DVB return-channel cable systems. It builds on standard MIB-II (RFC 1213) and adds objects for NIU configuration, network addressing, and operational status specific to DVB cable broadband subscriber units. Its monitoring focus is on the operational and connectivity health of the subscriber terminal: confirming the unit is provisioned with correct network addressing, reporting its DVB-specific operational state, and (via the underlying MIB-II dependency) exposing basic interface and system uptime status. This module explicitly depends on MIB-II (RFC 1213) as a foundation, layering DVB/EuroModem-specific objects on top. It is deployed on DVB cable subscriber premises equipment (NIUs) managed by a cable operator's head-end network management system in European DVB/DAVIC-based broadband cable deployments. Engineers implementing or auditing this functionality typically reference the DVB-CABLE-NIU-MIB RFC/standard documentation for the authoritative specification.
IPNetwork Monitor allows you to monitor SNMP objects defined in DVB-CABLE-NIU-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- vendor-neutral, standards-based MIB (DVB/DAVIC EuroModem spec)
- applies to DVB cable Network Interface Units (subscriber cable modems/terminals)
Monitoring Examples
No sample object names were included in the available source, so specific OIDs cannot be confirmed; based on the module description an operator would typically poll NIU addressing and operational-state objects to confirm a subscriber unit is registered and online, alongside the standard MIB-II ifTable/sysUpTime objects it depends on for basic interface and uptime status. A NIU reporting a non-operational or unregistered state would indicate a provisioning or return-channel connectivity problem at that subscriber's location.
What Can Be Monitored
- NIU network address/provisioning status
- NIU operational state
- basic interface status (via MIB-II)
- system uptime (via MIB-II)

Rows in this table may be created by either the create-and-go or create-and-wait paradigms. There is no restriction on changing values in a row of this table while the row is active. |
| dvbNiuEvent | 1.3.6.1.3.110.1.1.4 | |||
| INT dvbNiuEventPolicy | 1.3.6.1.3.110.1.1.4.1 | INTEGER | read-write | This defines event log policy. wrap When full the log wraps stop Stop event logging when full oneHour Clear the log at the start of every hour clearNow Clears the event log. Previous policy is restored. At initial startup this object has the default value of wrap(1). |
| dvbNiuEventControlTable | 1.3.6.1.3.110.1.1.4.2 | not-accessible | This table defines the action to be taken for the defined event priorities. A row will exist for each priority: Emergency, Alert, Critical, Error, Warning, Notice, Information and Debug. A bit field is used to identify the action to be taken for the event priority. Actions can be: place the event in the event table; issue an SNMP Trap | |
| dvbNiuEventControlEntry | 1.3.6.1.3.110.1.1.4.2.1 | not-accessible | There is a row per event and are recorded in chronological order. | |
| DVB dvbNiuEventControlPriority | 1.3.6.1.3.110.1.1.4.2.1.1 | DvbEventPriority | not-accessible | The priority level that is controlled by this entry. These are ordered from most (emergency) to least (debug) critical. Each event with a NIU has a particular priority level associated with it (as defined by the vendor). During normal operation no event more critical than notice(6) should be generated. Events between warning and emergency should be generated at appropriate levels of problems (e.g. emergency when the box is about to crash). |
| BIT dvbNiuEventControlAction | 1.3.6.1.3.110.1.1.4.2.1.2 | Bits | read-write | This defines the actions to perform when an event happens of this priority. local causes the event to be written to the local event log. trap causes a trap to be issued. |
| I32 dvbNiuEventTableMaxSize | 1.3.6.1.3.110.1.1.4.3 | Integer32 | read-only | The maximum number of entries the event log may hold |
| dvbNiuEventTable | 1.3.6.1.3.110.1.1.4.4 | not-accessible | Contains a log of network and device events that may be of interest in fault isolation and trouble shooting. | |
| dvbNiuEventEntry | 1.3.6.1.3.110.1.1.4.4.1 | not-accessible | Entries are created when an event occurrs. dvbNiuEventPolicy can be used to clear the table in addition individual events can be deleted. | |
| U32 dvbNiuEventIndex | 1.3.6.1.3.110.1.1.4.4.1.1 | Unsigned32 | not-accessible | This provides relative ordering of the objects in the event log. This object will always increase except when (a) the log is reset via dvbNiuEventPolicy, (b) the device reboots and does not implement non- volatile storage for this log, or (c) it reaches the value 2^31. The next entry for all the above cases is 1. |
| DVB dvbNiuEventType | 1.3.6.1.3.110.1.1.4.4.1.2 | DvbEventPriority | read-only | This is the priority of the event. |
| DAT dvbNiuEventDateTime | 1.3.6.1.3.110.1.1.4.4.1.3 | DateAndTime | read-only | This is the date and time the event occurred. |
| STR dvbNiuEventDescription | 1.3.6.1.3.110.1.1.4.4.1.4 | SnmpAdminString | read-only | This is a vendor specific textual description of the event. |
| STR dvbNiuEventCode | 1.3.6.1.3.110.1.1.4.4.1.5 | SnmpAdminString | read-only | This is the event code which uniquely identifies the event. The event codes should be in the form tppxxxxx where:- t - identifies who allocated the event identifier; d = dvb, v = vendor pp - identifies the priority; em = emergency, al = alert, cr = critical, er = error, wa = warning, no = notice, in = information, de = debug xxxxxxx - the event identifier which is 5 characters. |
| ROW dvbNiuEventStatus | 1.3.6.1.3.110.1.1.4.4.1.6 | RowStatus | read-write | This is used to delete individual events. The only valid management operation is destroy, which causes the event to be deleted. When read this object should always return active. |
| INT dvbNiuEvThrottleAdminStatus | 1.3.6.1.3.110.1.1.4.5 | INTEGER | read-write | Controls the transmission of traps with respect to the trap pacing threshold. unconstrained(1) causes traps to be transmitted without regard to the threshold settings. maintainBelowThreshold(2) causes trap transmission to be suppressed if the number of traps would otherwise exceed the threshold. stopAtThreshold(3) causes trap transmission to cease at the threshold, and not resume until directed to do so. See also RFC 1224. inhibited(4) causes all trap transmission messages to be suppressed. Writing to this object resets the thresholding state. At initial startup, this object has a default value of unconstrained(1). All the network managers with the trap capability as per RFC2573 will be treated as a single entity with regard to Trap management. This is done to simplify implementation within the NIU. |
| T/F dvbNiuEvThrottleInhibited | 1.3.6.1.3.110.1.1.4.6 | TruthValue | read-only | If true(1), trap is currently inhibited due to thresholds and/or the current setting of dvbNiuEvThrottleAdminStatus. In addition, this is set to true(1) if transmission is inhibited due to no trap (dvbNiuNmAccessEntry) destinations having been set. |
| U32 dvbNiuEvThrottleThreshold | 1.3.6.1.3.110.1.1.4.7 | Unsigned32 | read-write | Number of trap events per DvbNiuEvThrottleInterval to be transmitted before throttling. At initial startup, this object returns 0. |
| I32 dvbNiuEvThrottleInterval | 1.3.6.1.3.110.1.1.4.8 | Integer32 | read-write | The interval over which the trap threshold applies. At initial startup, this object has a value of 1. |
| dvbNiuIpFilter | 1.3.6.1.3.110.1.1.5 | |||
| INT dvbNiuIpFilterEnable | 1.3.6.1.3.110.1.1.5.1 | INTEGER | read-write | This controls the IP filter table. enable - Enables the IP filter table. countHits - This option is used to debug the filter table. It allows packets to be checked against the filter table and increments dvbNiuIpFilterMatches for a matching filter, but ALL PACKETS ARE ALLOWED THROUGH. disabled - Disables IP filtering, all packets are allowed through. At initial startup this object has the default value of disabled(4). |
| dvbNiuIpFilterTable | 1.3.6.1.3.110.1.1.5.2 | not-accessible | 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 which have matched no filters will be discarded i.e. no hits on any filter. 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 dvbNiuIpFilterAction and dvbNiuIpFilterActionPtr are taken. If the packet was discarded processing is complete. If dvbNiuIpFilterContinue is set to true, the filter comparison continues with the next row in the table looking for additional matches. | |
| dvbNiuIpFilterEntry | 1.3.6.1.3.110.1.1.5.2.1 | not-accessible | Describes a filter to apply to IP traffic received on a specified interface. All identity objects in this table (e.g. source and destination address/mask, protocol, source/dest port, TOS/mask, interface and direction) must match their respective fields in the packet for any given filter to match. To create an entry in this table, dvbNiuIpFilterIfIndex must be specified. | |
| U32 dvbNiuIpFilterIndex | 1.3.6.1.3.110.1.1.5.2.1.1 | Unsigned32 | not-accessible | Index used to order the application of filters. The filter with the lowest index is always applied first. |
| ROW dvbNiuIpFilterStatus | 1.3.6.1.3.110.1.1.5.2.1.2 | RowStatus | read-create | Controls and reflects the status of rows in this table. Specifying only this object (with the appropriate index) on a NIU is sufficient to create a filter row which matches all inbound packets on the Ethernet interface, and results in the packets being discarded. Creation of the rows may be done via either create-and-wait or create-and-go, but the filter is not applied until this object is set to (or changes to) active. There is no restriction in changing any object in a row while this object is set to active. |
| NUM dvbNiuIpFilterIfIndex | 1.3.6.1.3.110.1.1.5.2.1.4 | InterfaceIndexOrZero | read-create | The entry interface to which this filter applies. The value corresponds to ifIndex for either a CATV MAC or another network interface. If the value is zero, the filter applies to all interfaces. Default value in NIU is the index of the customer-side (e.g. ethernet) interface. |
| INT dvbNiuIpFilterDirection | 1.3.6.1.3.110.1.1.5.2.1.5 | INTEGER | read-create | Determines whether the filter is applied to inbound(1) traffic, outbound(2) traffic, or traffic in both(3) directions. |
| OCT dvbNiuIpFilterTos | 1.3.6.1.3.110.1.1.5.2.1.6 | OCTET STRING | read-create | This is the value to be matched to the packet's TOS (Type of Service) value (after the TOS value is AND'd with dvbNiuIpFilterTosMask). A value for this object of 0 and a mask of 0 matches all TOS values. |
| OCT dvbNiuIpFilterTosMask | 1.3.6.1.3.110.1.1.5.2.1.7 | OCTET STRING | read-create | The mask to be applied to the packet's TOS value before matching. |
| IPt dvbNiuIpFilterSrcAddrType | 1.3.6.1.3.110.1.1.5.2.1.8 | InetAddressType | read-create | The type of IP address for the source address. |
| IP dvbNiuIpFilterSrcAddr | 1.3.6.1.3.110.1.1.5.2.1.9 | InetAddress | read-create | The source IP address, or portion thereof, that is to be matched for this filter. The source address is first masked (and'ed) against dvbNiuIpFilterSrcMask before being compared to this value. A value of 0 for this object and 0 for the mask matches all IP addresses. |

| dvbNiuNatTable | 1.3.6.1.3.110.1.1.6.1 | not-accessible | This table is used to list external IP addresses available for assignment to internal IP addresses. The filter table is used to identify internal addresses that require NAT before entering the external domain (upstream). In the downstream direction NAT (inverse of the NAT applied in the upstream) is applied before applying the IP filter table. NAT assignment algorithims are vendor dependant. When an external IP address is no longer assigned to an IP addess, dvbNiuNatIntIp should be all 0's. If there are no free external addresses the packet requiring translation should be dropped. NAPT is not applicable to multicast packets. | |

At initial system startup, default value for this object is any(2). |
| I32 dvbNiuCpeIpMax | 1.3.6.1.3.110.1.1.9.2 | Integer32 | read-write | This object controls the maximum number of CPEs allowed to connect behind this device. If set to zero, any number of CPEs may connect up to the maximum permitted for the device or the maximum allowed for the subnet configured for the CPE (subscriber) interface, whichever is the smaller. If set to -1, no filtering is done on CPE source addresses, and no entries are made in the dvbNiuCpeTable. If an attempt is made to set this to a number greater than that permitted for the device/subnet, it is set to that maximum of the smallest value (device or subnet). At initial system startup, default value for this object is -1. |

If dvbNiuCpeIpMax is set to -1, this table is ignored, otherwise: Upon receipt of an IP packet from the customer interface of the CM, the source IP address is checked against this table. If the address is in the table, packet processing continues. If the address is not in the table, but dvbNiuCpeEnroll is set to any and the table size is less than dvbNiuCpeIpMax, the address is added to the table and packet processing continues. Otherwise, the packet is dropped. The filtering actions specified by this table occur after any Ethernet filtering (dvbNiuEthernetFilterTable), but prior to any IP filtering (dvbNiuIpFilterTable). | |
