M4300 Series and M4300-96X Fully Managed Switches User Manual
The following table describes the nonconfigurable information that is displayed.
Datagrams Successfully
Reassembled
The number of IPv6 datagrams successfully reassembled. This counter is
incremented at the interface to which these datagrams were addressed,
which might not be necessarily the input interface for some of the
fragments.
Datagrams Failed To Reassemble The number of failures detected by the IPv6 reassembly algorithm (for
whatever reason: timed out, errors, and so on).
This is not necessarily a
count of discarded IPv6 fragments since some algorithms (notably the
algorithm in RFC 815) can lose track of the number of fragments by
combining them as they are received.
This counter is incremented at the
interface to which these fragments were addressed, which might not be
the input interface for some of the fragments.
Datagrams Forwarded The number of output datagrams that this entity received and forwarded to
their final destinations. In entities that do not act as IPv6 routers, this
counter includes only those packets that were source-routed through this
entity
, and the source-route processing was successful. For a successfully
forwarded datagram the counter of the outgoing interface is incremented.
Datagrams Locally
Transmitted The number of datagrams that this entity successfully transmitted from
this output interface.
Datagrams Transmit Failed The number of datagrams that this entity failed to transmit successfully.
Datagrams Successfully
Fragmented
The number of IPv6 datagrams that were fragmented at this output
interface.
Datagrams Failed To Fragment The number of output datagrams that could not be fragmented at this
interface.
Datagrams Fragments Created The number of output datagram fragments that were generated as a result
of fragmentation at this output interface.
Multicast Datagrams Received The number of multicast packets received by the interface.
Multicast Datagrams Transmitted The number of multicast packets transmitted by the interface.
Table 113. ICMPv6 Statistics
Field Description
Total ICMPv6 Messages Received The total number of ICMP messages received by the interface, which
includes all those counted by IPv6IfIcmpInErrors. This interface is the
interface to which the ICMP messages were addressed, which might not
be the input interface for the messages.
ICMPv6 Messages With Errors
Received
The number of ICMP messages that the interface received but determined
as having ICMP-specific errors (bad ICMP checksums, bad length, and so
on).
ICMPv6 Destination Unreachable
Messages Received
The number of ICMP Destination Unreachable messages received by the
interface.
