Description: Huawei IP multicast MIB for managing PIM, IGMP, and multicast routing table entries and multicast forwarding on Huawei Layer 3 platforms.

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 HUAWEI-IPMCAST-MIB?

HUAWEI-IPMCAST-MIB is a Huawei enterprise MIB for managing IP multicast routing and forwarding on Huawei Layer 3 switches and routers, covering protocols such as PIM and IGMP referenced in its description. It exposes global multicast enable/disable state, multicast routing table size, and a per-interface table of multicast statistics and configuration. The MIB is squarely focused on operational/performance monitoring: it tracks per-interface multicast packet and octet counters (in/out), TTL and rate-limit settings, and the size of the multicast route table, letting an operator gauge multicast traffic volume and whether route-table growth is approaching capacity. It depends conceptually on standard IP multicast/PIM/IGMP concepts and complements the standard IETF IP-MIB and PIM-MIB rather than replacing them. It is deployed on Huawei carrier and enterprise routing/switching platforms delivering IPTV, video conferencing, or other multicast-distributed content where administrators need to monitor multicast traffic health per interface. Engineers can download the HUAWEI-IPMCAST-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-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

Huawei Layer 3 switches/routers

Monitoring Examples

An admin can poll hwIpMcastInterfaceTable/hwIpMcastInterfaceEntry (indexed by hwIpMcastInterfaceIfIndex and hwIpMcastInterfaceIpVersion) to read hwIpMcastInterfaceInMcastPkts and hwIpMcastInterfaceOutMcastOctets, spotting an interface whose multicast traffic has unexpectedly dropped to zero. Checking hwIpMcastRouteEntryCount against a configured maximum reveals multicast routing table pressure, while hwIpMcastInterfaceRateLimit shows whether rate-limiting is suppressing multicast forwarding on a given link.

What Can Be Monitored

multicast enable state
multicast route table size
per-interface multicast packet/octet counters
multicast rate-limit settings
interface TTL configuration

How to Use in IPNetwork Monitor

Example using hwIpMcastInterfaceInMcastOctets OID:

Select a Huawei Layer 3 switch or router (IP multicast routing/forwarding) 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 hwIpMcastInterfaceInMcastOctets 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 Counter64-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
I32 hwBoardIndex	1.3.6.1.4.1.2011.5.25.149.1.1.1.26	Integer32	accessible-for-notify	The BoardIndex of the trap.
hwIpMcast	1.3.6.1.4.1.2011.5.25.149.1.1.1
IP hwIpMcastBoundaryAddress	1.3.6.1.4.1.2011.5.25.149.1.1.1.7.1.3	InetAddress	not-accessible	The group address which, when combined with the corresponding value of hwIpMcastBoundaryAddressPrefixLength, 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 hwIpMcastBoundaryAddressPrefixLength 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. For addresses of type ipv4z or ipv6z, the appended zone index is significant even though it lies beyond the prefix length. Zone index zero is not valid in this table.
ADR hwIpMcastBoundaryAddressPrefixLength	1.3.6.1.4.1.2011.5.25.149.1.1.1.7.1.4	InetAddressPrefixLength	not-accessible	The length in bits of the mask which when, combined with the corresponding value of hwIpMcastBoundaryAddress, identifies the group range for which the scoped boundary exists.
IPt hwIpMcastBoundaryAddressType	1.3.6.1.4.1.2011.5.25.149.1.1.1.7.1.2	InetAddressType	not-accessible	A value indicating the address family of the address contained in hwIpMcastBoundaryAddress. Legal values correspond to the subset of address families for which multicast forwarding is supported.
C64 hwIpMcastBoundaryDroppedMcastOctets	1.3.6.1.4.1.2011.5.25.149.1.1.1.7.1.6	Counter64	read-only	The number of octets of multicast packets that have been dropped as a result of this zone boundary configuration. Discontinuities in this monotonically increasing value occur at re-initialization of the management system. Discontinuities can also occur as a result of boundary configuration being removed and replaced, which can be detected by observing the value of hwIpMcastBoundaryTimeStamp.
C64 hwIpMcastBoundaryDroppedMcastPkts	1.3.6.1.4.1.2011.5.25.149.1.1.1.7.1.7	Counter64	read-only	The number of multicast packets that have been dropped as a result of this zone boundary configuration. Discontinuities in this monotonically increasing value occur at re-initialization of the management system. Discontinuities can also occur as a result of boundary configuration being removed and replaced, which can be detected by observing the value of hwIpMcastBoundaryTimeStamp.
hwIpMcastBoundaryEntry	1.3.6.1.4.1.2011.5.25.149.1.1.1.7.1		not-accessible	An entry (conceptual row) describing one of this device's multicast scope zone boundaries.
NUM hwIpMcastBoundaryIfIndex	1.3.6.1.4.1.2011.5.25.149.1.1.1.7.1.1	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 hwIpMcastBoundaryStatus	1.3.6.1.4.1.2011.5.25.149.1.1.1.7.1.8	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 hwIpMcastBoundaryStorageType	1.3.6.1.4.1.2011.5.25.149.1.1.1.7.1.9	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.

For RPF checking protocols (such as PIM-SM), these packets arrived on interfaces other than hwIpMcastRouteInIfIndex, 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 hwIpMcastRouteOctets, 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 hwIpMcastRouteTimeStamp.

This address object is only significant up to hwIpMcastRouteGroupPrefixLength 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. For addresses of type ipv4z or ipv6z, the appended zone index is significant even though it lies beyond the prefix length. The use of these address types indicate that this forwarding state applies only within the given zone. Zone index zero is not valid in this table.

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.

If hwIpMcastRouteNextHopState 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 hwIpMcastRouteExpiryTime 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.
