Command Reference Guide
debug ip tcp
Use the debug ip tcp command to activate debug messages associated with Transmission Control Protocol
(TCP) state changes, session allocation and deallocation, and packet information (for example, sequence
numbers, acknowledgement numbers, and packet length) in AOS. Debug messages are displayed (real
time) to the terminal (or Telnet) screen. Use the no form of this command to disable the debug messages.
Variations of this command include:
debug ip tcp
debug ip tcp events
debug ip tcp md5
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.
Syntax Description

Functional Notes
The debug events for this command are logged for packets that are sent or received from the router.
Forwarded TCP packets are not included in the output.
In the debug ip tcp events output, 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.
