Object
column
SNMPv2-SMICounter32
The number of packets 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 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 alaIpMcastRoutePkts, 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.
