Description: Alcatel OmniSwitch MIB covering IP multicast, including forwarding state, statistics, and global multicast settings.
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 ALCATEL-IND1-IPMCAST-MIB?
ALCATEL-IND1-IPMCAST-MIB is an Alcatel(-Lucent) vendor-private MIB, modeled on the IETF MBONED working group's draft IP multicast MIB, that manages IP multicast routing and forwarding state on Alcatel OmniSwitch platforms independent of the specific multicast protocol or address family in use. Its global alaIpMcastEnable object turns IP multicast routing on or off system-wide, while alaIpMcastRouteEntryCount tracks multicast routing-table size. The alaIpMcastInterfaceTable records which multicast protocol is active per interface, the alaIpMcastRouteTable holds the multicast forwarding/routing entries themselves, alaIpMcastRouteNextHopTable enumerates the outgoing interfaces/next hops for each route, and alaIpMcastBoundaryTable defines administrative scope boundaries that block multicast traffic for specific group ranges on specific interfaces. This is useful for confirming multicast routing is enabled and populated as expected, diagnosing why a multicast stream is not reaching a downstream interface, and verifying that scope boundaries are correctly containing traffic. It depends on the underlying multicast routing protocol (PIM, DVMRP, etc.) actually populating these tables, and is deployed on Alcatel OmniSwitch multicast-capable switches, and administrators can download the ALCATEL-IND1-IPMCAST-MIB file for building multicast monitoring tools.
IPNetwork Monitor allows you to monitor SNMP objects defined in ALCATEL-IND1-IPMCAST-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
- Alcatel/Alcatel-Lucent OmniSwitch multicast-capable switches
Monitoring Examples
An operator polls alaIpMcastRouteEntryCount and alaIpMcastRouteTable to confirm a multicast group's route exists and checks alaIpMcastRouteNextHopTable for the expected outgoing interfaces; an empty route entry combined with alaIpMcastEnable showing enabled would indicate the multicast routing protocol has not yet installed forwarding state for that group.
What Can Be Monitored
- global IP multicast enable state
- multicast route table entry count
- per-interface multicast protocol activity
- multicast route next-hop/outgoing-interface entries
- multicast scope boundary entries

How to Use in IPNetwork Monitor
Example using alaIpMcastInterfaceInMcastOctets OID:
Select an Alcatel-Lucent Enterprise OmniSwitch switch as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type alaIpMcastInterfaceInMcastOctets into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The number of octets of multicast packets that have arrived on the interface, including framing characters. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
OIDs
| OID symbolic | OID numeric | Type | Access | Description |
|---|---|---|---|---|
| alaIpMcast | 1.3.6.1.4.1.6486.801.1.2.1.10.10.2.1.1 | |||
| IP alaIpMcastBoundaryAddress | 1.3.6.1.4.1.6486.801.1.2.1.10.10.2.1.1.5.1.3 | InetAddress | not-accessible | The group address which, when combined with the corresponding value of alaIpMcastBoundaryAddressPrefixLength, identifies the group range for which the scoped boundary exists. Scoped IPv4 multicast address ranges must be prefixed by 239.0.0.0/4. Scoped IPv6 multicast address ranges are FF0x::/16, where x is a valid RFC 4291 multicast scope. An IPv6 address prefixed by FF1x::/16 is a non-permanently- assigned address. An IPv6 address prefixed by FF3x::/16 is a unicast-prefix based multicast addresses. A zone boundary for FF0x::/16 implies an identical boundary for these other prefixes. No separate FF1x::/16 or FF3x::/16 entries exist in this table. This address object is only significant up to alaIpMcastBoundaryAddressPrefixLength bits. The remainder of the address bits are zero. This is especially important for this index field, which is part of the index of this entry. Any non-zero bits would signify an entirely different entry. |
| ADR alaIpMcastBoundaryAddressPrefixLength | 1.3.6.1.4.1.6486.801.1.2.1.10.10.2.1.1.5.1.4 | InetAddressPrefixLength | not-accessible | The length in bits of the mask which when, combined with the corresponding value of alaIpMcastBoundaryAddress, identifies the group range for which the scoped boundary exists. The InetAddressType is given by alaIpMcastBoundaryAddressType. For 'ipv4' this object must be in the range 4..32. For 'ipv6', this object must be 32. |
| IPt alaIpMcastBoundaryAddressType | 1.3.6.1.4.1.6486.801.1.2.1.10.10.2.1.1.5.1.2 | InetAddressType | not-accessible | A value indicating the address family of the address contained in alaIpMcastBoundaryAddress. Legal values correspond to the subset of address families for which multicast forwarding is supported. |
| C32 alaIpMcastBoundaryDroppedMcastOctets | 1.3.6.1.4.1.6486.801.1.2.1.10.10.2.1.1.5.1.7 | Counter32 | read-only | The number of octets of multicast packets that have been dropped as a result of this zone boundary configuration. |

This object is a 64-bit version of alaIpMcastBoundaryDroppedMcastOctets. |
| C64 alaIpMcastBoundaryHCDroppedMcastPkts | 1.3.6.1.4.1.6486.801.1.2.1.10.10.2.1.1.5.1.10 | Counter64 | read-only | The number of multicast packets that have been dropped as a result of this zone boundary configuration. This object is a 64-bit version of alaIpMcastBoundaryDroppedMcastPkts. |
| NUM alaIpMcastBoundaryIfIndex | 1.3.6.1.4.1.6486.801.1.2.1.10.10.2.1.1.5.1.1 | InterfaceIndex | not-accessible | The IfIndex value for the interface to which this boundary applies. Packets with a destination address in the associated address/mask range will not be forwarded over this interface. For IPv4, zone boundaries cut through links. Therefore this is an external interface. This may be either a physical or virtual interface (tunnel, encapsulation, and so forth.) For IPv6, zone boundaries cut through nodes. Therefore this is a virtual interface within the node. This is not an external interface, either real or virtual. Packets crossing this interface neither arrive at nor leave the node, but only move between zones within the node. |
| ROW alaIpMcastBoundaryStatus | 1.3.6.1.4.1.6486.801.1.2.1.10.10.2.1.1.5.1.5 | RowStatus | read-create | The status of this row, by which rows in this table can be created and destroyed. This status object can be set to active(1) without setting any other columnar objects in this entry. All writeable objects in this entry can be modified when the status of this entry is active(1). |
| STO alaIpMcastBoundaryStorageType | 1.3.6.1.4.1.6486.801.1.2.1.10.10.2.1.1.5.1.6 | StorageType | read-create | The storage type for this row. Rows having the value 'permanent' need not allow write-access to any columnar objects in the row. |

In many cases, this object is identical to ifHCInMulticastPkts in the Interfaces MIB. However, some implementations use ifXTable for Layer 2 traffic statistics and alaIpMcastInterfaceTable at Layer 3. In this case a difference between these objects probably indicates that some Layer 3 multicast packets are being transmitted as unicast at Layer 2. |
| C64 alaIpMcastInterfaceHCOutMcastOctets | 1.3.6.1.4.1.6486.801.1.2.1.10.10.2.1.1.4.1.10 | Counter64 | read-only | The number of octets of multicast packets that have been sent on the interface. This object is a 64-bit version of alaIpMcastRouteInterfaceOutMcastOctets. |

In many cases, this object is identical to ifInMulticastPkts in the Interfaces MIB. However, some implementations use ifXTable for Layer 2 traffic statistics and alaIpMcastInterfaceTable at Layer 3. In this case a difference between these objects probably indicates that some Layer 3 multicast packets are being transmitted as unicast at Layer 2. |

In many cases, this object is identical to ifOutMulticastPkts in the Interfaces MIB. However, some implementations use ifXTable for Layer 2 traffic statistics and alaIpMcastInterfaceTable at Layer 3. In this case a difference between these objects probably indicates that some Layer 3 multicast packets are being transmitted as unicast at Layer 2. |
| IAN alaIpMcastInterfaceProtocol | 1.3.6.1.4.1.6486.801.1.2.1.10.10.2.1.1.4.1.3 | IANAipMRouteProtocol | read-write | The multicast protocol running on this interface. More than one multicast protocol can be used on an interface, so this object is ambiguous. Use of this object is deprecated. |
| U32 alaIpMcastInterfaceRateLimit | 1.3.6.1.4.1.6486.801.1.2.1.10.10.2.1.1.4.1.4 | Unsigned32 | read-write | The rate-limit, in kilobits per second, of forwarded multicast traffic on the interface. A rate-limit of 0 indicates that no rate limiting is done. |
| alaIpMcastInterfaceTable | 1.3.6.1.4.1.6486.801.1.2.1.10.10.2.1.1.4 | not-accessible | The (conceptual) table used to manage the multicast protocol active on an interface. | |
| U32 alaIpMcastInterfaceTtl | 1.3.6.1.4.1.6486.801.1.2.1.10.10.2.1.1.4.1.2 | Unsigned32 | read-write | The datagram TTL threshold for the interface. Any IP multicast datagrams with a TTL (IPv4) or Hop Limit (IPv6) less than this threshold will not be forwarded out the interface. The default value of 0 means all multicast packets are forwarded out the interface. |

For RPF checking protocols (such as PIM-SM), these packets arrived on interfaces other than alaIpMcastRouteInIfIndex, and were dropped because of this failed RPF check. (RPF paths are 'Reverse Path Forwarding' path; the unicast routes to the expected origin of multicast data flows). Other protocols may drop packets on an incoming interface check for different reasons (for example, BIDIR-PIM performs a DF check on receipt of packets). All packets dropped as a result of an incoming interface check are counted here. If this counter increases rapidly, this indicates a problem. A significant quantity of multicast data is arriving at this router on unexpected interfaces, and is not being forwarded. For guidance, if the rate of increase of this counter exceeds 1% of the rate of increase of alaIpMcastRouteOctets, then there are multicast routing problems that require investigation. Discontinuities in this monotonically increasing value occur at re-initialization of the management system. Discontinuities can also occur as a result of routes being removed and replaced, which can be detected by observing the value of alaIpMcastRouteTimeStamp. |

The value 0 indicates that the entry is not subject to aging. If alaIpMcastRouteNextHopState is pruned(1), this object represents the remaining time until the prune expires. If this timer expires, state reverts to forwarding(2). Otherwise, this object represents the time until this entry is removed from the table. |
| IP alaIpMcastRouteGroup | 1.3.6.1.4.1.6486.801.1.2.1.10.10.2.1.1.2.1.2 | InetAddress | not-accessible | The IP multicast group address which, when combined with the corresponding value specified in alaIpMcastRouteGroupPrefixLength, identifies the groups for which this entry contains multicast routing information. This address object is only significant up to alaIpMcastRouteGroupPrefixLength bits. The remainder of the address bits are zero.

This object is a 64-bit version of alaIpMcastRouteOctets. Discontinuities in this monotonically increasing value occur at re-initialization of the management system. Discontinuities can also occur as a result of routes being removed and replaced, which can be detected by observing the value of alaIpMcastRouteTimeStamp. |
| NUM alaIpMcastRouteInIfIndex | 1.3.6.1.4.1.6486.801.1.2.1.10.10.2.1.1.2.1.9 | InterfaceIndexOrZero | read-only | The value of ifIndex for the interface on which IP datagrams sent by these sources to this multicast address are received. A value of 0 indicates that datagrams are not subject to an incoming interface check, but may be accepted on multiple interfaces (for example, in BIDIR-PIM). |
| IP alaIpMcastRouteNextHopAddress | 1.3.6.1.4.1.6486.801.1.2.1.10.10.2.1.1.3.1.8 | InetAddress | not-accessible | The address of the next-hop specific to this entry.

Any IP multicast datagrams for the group which have a TTL (IPv4) or Hop Count (IPv6) less than this number of hops will not be forwarded to this next-hop. This is an optimization applied by multicast routing protocols that explicitly track hop counts to downstream listeners. Multicast protocols that are not aware of hop counts to downstream listeners set this object to zero. |
| alaIpMcastRouteNextHopEntry | 1.3.6.1.4.1.6486.801.1.2.1.10.10.2.1.1.3.1 | not-accessible | An entry (conceptual row) in the list of next-hops on outgoing interfaces to which IP multicast datagrams from particular sources to an IP multicast group address are routed. | |

If alaIpMcastRouteNextHopState is pruned(1), the remaining time until the prune expires and the state reverts to forwarding(2). Otherwise, the remaining time until this entry is removed from the table. The time remaining may be copied from alaIpMcastRouteExpiryTime if the protocol in use for this entry does not specify next-hop timers. The value 0 indicates that the entry is not subject to aging. |
