Luc Morissette: New VOIP capture page specific to TMG800

2015-02-24T16:37:11Z

New VOIP capture page specific to TMG800

New page

=== '''''Applies to version v2.7''''' ===
{{DISPLAYTITLE:Capturing VOIP traffic on TMG800}}

== Capturing using the TMG800's internal host ==
The TMG800's internal host can be used for capturing packets that are mirrored from the VOIP0 and/or VOIP1 physical ports.

=== TMG800 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 '''tml>''' ) 
To capture VoIP0 traffic:
mv88eMonitor 0x1 0x1 2 600
To capture VoIP1 traffic:
mv88eMonitor 0x2 0x2 2 600
In the example the duration is 600 seconds, thus will capture traffic for 10 minutes
 
 
'''Second''', access the [[Tmedia]] management interface using SSH ( prompt is '''[root@TBxxxxxx ~]#''' ) 
tcpdump -i mgmt0 -s 1500 -w capture_file.cap
You will see something like this:
tcpdump: listening on mgmt0, link-type EN10MB (Ethernet), capture size 1500 bytes

=== Stop the 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

=== Download the Capture ===
To download the capture, 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
