Table 62 TCP statistics

Statistics

Description

 

 

tcpRtoMax

The maximum value permitted by a TCP implementation for the retransmission timeout,

 

measured in milliseconds. More refined semantics for objects of this type depend upon

 

the algorithm used to determine the retransmission timeout. In particular, when the

 

timeout algorithm is rsre(3), an object of this type has the semantics of the UBOUND

 

quantity described in RFC 793.

 

 

tcpMaxConn

The limit on the total number of TCP connections the switch can support. In entities

 

where the maximum number of connections is dynamic, this object should contain the

 

value -1.

 

 

tcpActiveOpens

The number of times TCP connections have made a direct transition to the SYN-SENT

 

state from the CLOSED state.

 

 

tcpPassiveOpens

The number of times TCP connections have made a direct transition to the SYN-RCVD

 

state from the LISTEN state.

 

 

tcpAttemptFails

The number of times TCP connections have made a direct transition to the CLOSED state

 

from either the SYN-SENT state or the SYN-RCVD state, plus the number of times TCP

 

connections have made a direct transition to the LISTEN state from the SYN-RCVD state.

 

 

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.

 

 

tcpInSegs

The total number of segments received, including those received in error. This count

 

includes segments received on currently established connections.

 

 

tcpOutSegs

The total number of segments sent, including those on current connections but excluding

 

those containing only retransmitted octets.

 

 

tcpRetransSegs

The total number of segments retransmitted, that is, the number of TCP segments

 

transmitted containing one or more previously transmitted octets.

 

 

tcpInErrs

The total number of segments received in error (for example, bad TCP checksums).

 

 

tcpCurBuff

The total number of outstanding memory allocations from heap by TCP protocol stack.

 

 

tcpCurConn

The total number of outstanding TCP sessions that are currently opened.

 

 

tcpOutRsts

The number of TCP segments sent containing the reset (RST) flag.

Statistics

Description

 

 

udpInDatagrams

The total number of UDP datagrams delivered to the switch.

 

 

udpOutDatagrams

The total number of UDP datagrams sent from this switch.

 

 

udpInErrors

The number of received UDP datagrams that could not be delivered for reasons other

 

than the lack of an application at the destination port.

 

 

udpNoPorts

The total number of received UDP datagrams for which there was no application at the

 

destination port.
