TcpEstabResets
The number of times TCP connections have made
a direct transition to the CLOSED state from either
the ESTABLISHED state or the CLOSE-WAIT state.
Supported.
TcpCurrEstab
The number of TCP connections for which the
current state is either ESTABLISHED or CLOSE-
WAIT.
Supported.
TcpInSegs
The total number of segments received, including
those received in error. This count includes
segments received on currently established
connections.
Supported.
TcpOutSegs
The total number of segments sent, including those
on current connections but excluding those
containing only retransmitted octets.
Supported.
TcpSlowOutSegs
This is a subset of TcpOutSegs. It is the total
number of segments sent in the slow path.
Supported.
TcpRetransSegs
The total number of segments retransmitted - that
is, the number of TCP segments transmitted
containing one or more previously transmitted
octets.
Supported.
TcpInErrs
The total number of segments received in error
(e.g., bad TCP header). Checksum errors are not
included in this counter.
Supported.
TcpOutRsts
The number of TCP segments sent containing the
RST flag.
Supported.
TcpOutCollapsed
The total number of times two outgoing packets
were collapsed to form a single packet during
retransmission.
Supported.
TcpTimeWaitConns
The total number of connections currently in
TIME_WAIT state.
Supported.
IP Statistics
IpInReceives
The total number of input datagrams received from
interfaces, including those received in error.
Supported.
IpInHdrErrors
The number of input datagrams discarded due to
errors in their IP headers, including bad
checksums, version number mismatch, other
format errors, time-to-live exceeded, errors
discovered in processing their IP options, etc.
Supported.
IpInAddrErrors
The number of input datagrams discarded because
the IP address in their IP header's destination field
was not a valid address to be received at this entity.
This count. includes invalid addresses (e.g.,
0.0.0.0) and addresses of unsupported Classes
(e.g., Class E). For entities which are not IP routers
and therefore do not forward datagrams, this
counter includes datagrams discarded because the
destination address was not a local address.
These are accounted by the
host stack and not in the
offload path.
IpInNoRoutes
(Not in ip-mib)
Number of input datagrams discarded because
there was a problem with either determination of
inbound interface or a problem with determination
of a route back to the source of the datagram.
Supported.
