TCPTRACE
TCPTRACE
Traces packets between two hosts.
Format
TCPTRACE host [/BUFFERS=n | /FULL | /OUTPUT=file | /PACKETS=n | /PORT=option |
/PROTOCOL=option]
Description
TCPTRACE traces packets as they travel between the local and remote host. You
can trace all packets or you can use command qualifiers to monitor only those
packets of interest.
Qualifiers
/BUFFERS=n
Optional. The default is 100.
Specifies the number of buffers that TCPTRACE allocates for temporary storage.
These buffers must be locked into the working set, so the number can be:
• Decreased (to be accommodated in the working set)
• Raised (to prevent the dropping of trace packets)
/FULL
Optional. The default is brief display.
Displays the packet’s contents.
/OUTPUT=file
Optional. The default is screen display. Redirects the output from screen to the
specified file. If this file name already exists, the output is appended to it.
/PACKETS=n
Optional. The default it 10.
Stops the trace after the specified number of packets is displayed.
/PORT={LOCAL=n | REMOTE=n}
Optional for port number. The default is that all traffic is displayed.
Required for port type. Filters the trace to the specified port.
/PROTOCOL={ARP | ICMP | IP | TCP | UDP}
Optional. The default is /PROTOCOL=IP.
Filters the specified protocol.
