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.
These debug events are logged for packets that are sent or received from the router.
Forwarded TCP packets are not included.
