The MIB module for management of IP Multicast, including multicast routing, data forwarding, and data reception. Huawei Technologies Co.,Ltd . Supplementary information may be available at: http://www.huawei.com

The enabled status of IP Multicast function on this system.

The number of rows in the hwIpMcastRouteTable. This can be used to check for multicast routing activity, and to monitor the multicast routing table size.

The (conceptual) table used to manage the multicast protocol active on an interface.

An entry (conceptual row) containing the multicast protocol information for a particular interface.

The IP version of this row.

The index value that uniquely identifies the interface to which this entry is applicable. The interface identified by a particular value of this index is the same interface as identified by the same value of the IF-MIB's ifIndex.

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.

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.

The number of octets of multicast packets that have arrived on the interface, including framing characters. This object is similar to ifInOctets in the Interfaces MIB, except that only multicast packets are counted. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of hwIpMcastInterfaceDiscontinuityTime.

The number of octets of multicast packets that have been sent on the interface, including framing characters. This object is similar to ifOutOctets in the Interfaces MIB, except that only multicast packets are counted. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of hwIpMcastInterfaceDiscontinuityTime.

The number of multicast packets that have arrived on the interface. In many cases, this object is identical to ifInMulticastPkts in the Interfaces MIB. However, some implementations use ifXTable for Layer 2 traffic statistics and hwIpMcastInterfaceTable 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. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of hwIpMcastInterfaceDiscontinuityTime.

The value of sysUpTime on the most recent occasion at which any one or more of this entry's counters suffered a discontinuity. If no such discontinuities have occurred since the last re- initialization of the local management subsystem, then this object contains a zero value.

The (conceptual) table containing multicast routing information for IP datagrams sent by particular sources to to the IP multicast groups known to this router.

An entry (conceptual row) containing the multicast routing information for IP datagrams from a particular source and addressed to a particular IP multicast group address.

A value indicating the address family of the address contained in hwIpMcastRouteGroup. Legal values correspond to the subset of address families for which multicast forwarding is supported.

The IP multicast group address which, when combined with the corresponding value specified in hwIpMcastRouteGroupPrefixLength, identifies the groups for which this entry contains multicast routing information. 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.

The length in bits of the mask which, when combined with the corresponding value of hwIpMcastRouteGroup, identifies the groups for which this entry contains multicast routing information.

A value indicating the address family of the address contained in hwIpMcastRouteSource. The value MUST be the same as the value of IpMcastRouteGroupType.

The network address which, when combined with the corresponding value of hwIpMcastRouteSourcePrefixLength, identifies the sources for which this entry contains multicast routing information. 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 source address applies only within the given zone. Zone index zero is not valid in this table.

The length in bits of the mask which, when combined with the corresponding value of hwIpMcastRouteSource, identifies the sources for which this entry contains multicast routing information.

A value indicating the address family of the address contained in hwIpMcastRouteUpstreamNeighbor. An address type of unknown(0) indicates that the upstream neighbor is unknown, for example in BIDIR-PIM.

The address of the upstream neighbor (for example, RPF neighbor) from which IP datagrams from these sources to this multicast address are received.

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).

The value of sysUpTime at which the multicast routing information represented by this entry was learned by the router. If this infomration was present at the most recent re- initialization of the local management subsystem, then this object contains a zero value.

The minimum amount of time remaining before this entry will be aged out. The value 0 indicates that the entry is not subject to aging. If hwIpMcastRouteNextHopState 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.

The multicast routing protocol via which this multicast forwarding entry was learned.

The routing mechanism via which the route used to find the upstream or parent interface for this multicast forwarding entry was learned.

A value indicating the address family of the address contained in hwIpMcastRouteRtAddress.

The address portion of the route used to find the upstream or parent interface for this multicast forwarding entry. This address object is only significant up to hwIpMcastRouteGroupPrefixLength bits. The remainder of the address bits are zero. 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.

The length in bits of the mask associated with the route used to find the upstream or parent interface for this multicast forwarding entry.

The reason the given route was placed in the (logical) multicast Routing Information Base (RIB). A value of unicast means that the route would normally be placed only in the unicast RIB, but was placed in the multicast RIB (instead or in addition) due to local configuration, such as when running PIM over RIP. A value of multicast means that the route was explicitly added to the multicast RIB by the routing protocol, such as DVMRP or Multiprotocol BGP. Enumeration: 'unicast': 1, 'multicast': 2.

The number of octets contained in IP datagrams which were received from these sources and addressed to this multicast group address, and which were forwarded by this router. 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.

The number of packets routed using this multicast route entry. 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.

The number of octets contained in IP datagrams which this router has received from these sources and addressed to this multicast group address, which were dropped because the TTL (IPv4) or Hop Limit (IPv6) was decremented to zero, or to a value less than hwIpMcastInterfaceTtl for all next hops. 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.

The number of packets which this router has received from these sources and addressed to this multicast group address, which were dropped because the TTL (IPv4) or Hop Limit (IPv6) was decremented to zero, or to a value less than hwIpMcastInterfaceTtl for all next hops. 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.

The number of octets contained in IP datagrams which this router has received from these sources and addressed to this multicast group address, which were dropped because they were received on an unexpected interface. 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.

A value indicating the address family of the address contained in hwIpMcastRouteNextHopSource. The value MUST be the same as the value of IpMcastRouteNextHopGroupType.

The network address which, when combined with the corresponding value of the mask specified in hwIpMcastRouteNextHopSourcePrefixLength, identifies the sources for which this entry specifies a next-hop on an outgoing interface. This address object is only significant up to hwIpMcastRouteNextHopSourcePrefixLength 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 source address applies only within the given zone. Zone index zero is not valid in this table.

The length in bits of the mask which, when combined with the corresponding value specified in hwIpMcastRouteNextHopSource, identifies the sources for which this entry specifies a next-hop on an outgoing interface.

The ifIndex value of the interface for the outgoing interface for this next-hop.

A value indicating the address family of the address contained in hwIpMcastRouteNextHopAddress.

The address of the next-hop specific to this entry. For most interfaces, this is identical to hwIpMcastRouteNextHopGroup. NBMA interfaces, however, may have multiple next-hop addresses out a single outgoing interface.

An indication of whether the outgoing interface and next- hop represented by this entry is currently being used to forward IP datagrams. The value 'forwarding' indicates it is currently being used; the value 'pruned' indicates it is not. Enumeration: 'pruned': 1, 'forwarding': 2.

The value of sysUpTime at which the multicast routing information represented by this entry was learned by the router. If this infomration was present at the most recent re- initialization of the local management subsystem, then this object contains a zero value.

The minimum amount of time remaining before this entry will be aged out. 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.

The minimum number of hops between this router and any member of this IP multicast group reached via this next-hop on this outgoing interface. 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.

The routing mechanism via which this next-hop was learned.

The number of octets of multicast packets that have been forwarded using this route. 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 hwIpMcastRouteNextHopTimeStamp.

The (conceptual) table listing the system's multicast scope zone boundaries.

An entry (conceptual row) describing one of this device's multicast scope zone boundaries.

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.

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.

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.

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.
