== Capturing using the TMG3200's internal host ==
The TMG3200's internal host can be used for capturing packets that are mirrored from the VOIP0 and/or VOIP1 physical ports.

=== Start Capture ===
You need '''two''' SSH sessions to capture the traffic: 

'''First''', access the [[Tmedia]] management interface using SSH. Then, access the telecom baseboard using
telnet 172.31.1.1
Prompt is now:
0/tbgw>
To capture VoIP0 traffic:
mv88eMonitor 0x4 0x4 8 600
To capture VoIP1 traffic:
mv88eMonitor 0x8 0x8 8 600
In the example the duration is 600 seconds, thus will capture traffic for 10 minutes.

Note: We don't recommend to keep the capturing for a long time. This is only for debugging purpose.
 
 
'''Second''', access the [[Tmedia]] management interface using SSH 
Prompt is now:
[root@TBxxxxxx ~]#
To dump the content of the VOIP traffic in the file voip_capture.cap
tcpdump -i int0 -s 1500 -w voip_capture.cap
You will see something like this:
tcpdump: listening on mgmt0, link-type EN10MB (Ethernet), capture size 1500 bytes

=== Stop Capture ===
When you're ready, stop the capture by pressing '''control-C''' on the shell that was running tcpdump command 
You will see something like this:
364 packets captured
590 packets received by filter
0 packets dropped by kernel

*Access the telecom baseboard from the [[Tmedia]] using telnet.
telnet 172.31.1.1
*Stop the capture
mv88eMonitor 0 0 0

=== Download Capture ===
To download the voip_capture.cap file, use SSH secure copy ("sftp") to the Tmedia management port. This can be done on Windows using tools like '''Filezilla''' or '''WinSCP'''. 
The file will be located in
/root
