debug ip tcp [events]
Use the
debug ip tcp events
command to activate debug messages associated with significant TCP events
such as state changes, retransmissions, session aborts, etc., in the SROS. Debug messages are displayed
(real-time) to the terminal (or Telnet) screen. Use the
no
form of this command to disable the debug
messages.
Syntax Description
events
Optional. Displays only TCP protocol events.
Default Values
By default, all debug messages in the SROS are disabled.
Functional Notes
In the
debug ip tcp events
information, TCB stands for TCP task control block. The numbers which
sometimes appear next to TCB (e.g.,
TCB5
in the following example) represent the TCP session number.
This allows you to differentiate debug messages for multiple TCP sessions.
Usage Examples
The following is sample output for this command:
ProCurve>
enable
ProCurve#
debug ip tcp events
2003.02.17 07:40:56 IP.TCP EVENTS TCP: Allocating block 5
2003.02.17 07:40:56 IP.TCP EVENTS TCB5: state change: FREE->SYNRCVD
2003.02.17 07:40:56 IP.TCP EVENTS TCB5: new connection from 172.22.75.246:3473 to
10.200.2.201:23
2003.02.17 07:40:56 IP.TCP EVENTS TCB5: state change: SYNRCVD->ESTABLISHED
[172.22.75.246:3473]
2003.02.17 07:41:06 IP.TCP EVENTS TCB5: Connection aborted -- error = RESET
2003.02.17 07:41:06 IP.TCP EVENTS TCB5: De-allocating tcb
Note
These debug events are logged for packets that are sent or received from the router.
Forwarded TCP packets are not included.
Turning on a large amount of debug information can adversely affect the performance of
your unit.
