Statistics | Description |
|
|
tcpRtoMin | The minimum 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 LBOUND quantity |
| described in Request For Comments (RFC) 793. |
|
|
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 |
|
|
tcpActiveOpens | The number of times TCP connections have made a direct transition to the |
| from the CLOSED state. |
|
|
tcpPassiveOpens | The number of times TCP connections have made a direct transition to the |
| from the LISTEN state. |
|
|
tcpAttemptFails | The number of times TCP connections have made a direct transition to the CLOSED state |
| from either the |
| connections have made a direct transition to the LISTEN state from the |
|
|
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. |
