Object
column SNMPv2-SMICounter64
The number of packets that this router has received from
the sources represented by this entry and addressed to this
multicast group address, which were dropped due to
Time To Live (TTL) issues. TTL issues occur when the
TTL (IPv4) or Hop Limit (IPv6) of the incoming packet was
decremented to zero or to a value less than
ipMcastInterfaceTtl of the corresponding interface.
The ipMcastInterfaceTtl object is defined in IPMCAST-MIB
(RFC 5132) and represents 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 of the interface.
The default value of zero means all multicast packets are
forwarded out of the interface. A value of 256 means that
no multicast packets are forwarded out of the interface.
Discontinuities in the value of this counter can
occur at re-initialization of the management system
and at other times as indicated by the corresponding
mvpnMrouteCounterDiscontinuityTime object.
