Members

dwGroup

Type: DWORD

The multicast group for this MFE. A value of zero indicates a wildcard group.

dwSource

Type: DWORD

The range of source addresses for this MFE. A value of zero indicates a wildcard source.

dwSrcMask

Type: DWORD

The IPv4 subnet mask that corresponds to dwSourceAddr. The dwSourceAddr and dwSourceMask members are used together to define a range of sources.

dwUpStrmNgbr

Type: DWORD

The upstream neighbor that is related to this MFE.

dwInIfIndex

Type: DWORD

The index of the incoming interface to which this MFE is related.

dwInIfProtocol

Type: DWORD

The routing protocol that owns the incoming interface to which this MFE is related.

dwRouteProtocol

Type: DWORD

The client that created the route.

dwRouteNetwork

Type: DWORD

The address associated with the route referred to by dwRouteProtocol.

dwRouteMask

Type: DWORD

The mask associated with the route referred to by dwRouteProtocol.

ulUpTime

Type: ULONG

The time, in 100ths of a seconds, since the MFE was created.

ulExpiryTime

Type: ULONG

The time, in 100ths of a seconds, until the MFE will be deleted. Zero is specified if the MFE is not subject to aging requirements.

ulNumOutIf

Type: ULONG

The number of interfaces in the outgoing interface list for this MFE.

ulInPkts

Type: ULONG

The number of packets that have been forwarded that matched this MFE.

ulInOctets

Type: ULONG

The number of octets of data forwarded that match this MFE.

ulPktsDifferentIf

Type: ULONG

The number of packets matching this MFE that were dropped due to an incoming interface check.

ulQueueOverflow

Type: ULONG

The number of packets matching this MFE that were dropped due to a queue overflow. There is one queue per MFE.

ulUninitMfe

Type: ULONG

The number of uninitialized packets that matched this MFE.

ulNegativeMfe

Type: ULONG

The number of packets matching this MFE discarded due to a negative error value.

ulInDiscards

Type: ULONG

The number of discarded forwarded packets that matched this MFE.

ulInHdrErrors

Type: ULONG

The number of packets matching this MFE discarded due to bad or malformed header values (such as a bad Time-to-Live value).

ulTotalOutPackets

Type: ULONG

The total number of MFE packets transmitted across all associated interfaces. Note that one packet sent over N interfaces will count as N packets within this value.

Remarks

The MIB_IPMCAST_MFE_STATS_EX structure extends the functionality of MIB_IPMCAST_MFE_STATS by including additional information on MFE packets.

This structure does not have a fixed size. Use the SIZEOF_MIB_MFE_STATS_EX(X) macro to determine the size of this structure. This macro is defined in the Iprtrmib.h header file.

The dwRouteProtocol, dwRouteNetwork, and dwRouteMask members uniquely identify the route to which this MFE is related.

On the Microsoft Windows Software Development Kit (SDK) released for Windows Vista and later, the organization of header files has changed. This structure is defined in the Ipmib.h header file, not in the Iprtrmib.h header file. Note that the Ipmib.h header file is automatically included in Iprtrmib.h, which is automatically included in the Iphlpapi.h header file. The Ipmib.h and Iprtrmib.h header files should never be used directly.

Requirements

Minimum supported client

None supported

Minimum supported server

Windows Server 2008, Windows Server 2003 with SP1 [desktop apps only]

Header

Ipmib.h on Windows Server 2008 (include Iphlpapi.h);
Iprtrmib.h on Windows Server 2003 with SP1 (include Iphlpapi.h)
