== Capturing using the internal host of the SN10500 unit==
The internal host of the SN10500 can be used for capturing packets that are mirrored from the VOIP0 and/or VOIP1 physical ports. This includes RTP traffic.
 
=== Start Capture ===
You need '''two''' SSH sessions to capture the traffic: <br />
 
'''Step 1'''
*Access the SN10500 management interface using SSH. Then, access the telecom baseboard using telnet:
telnet [eth0 IP address of the telecom unit]
 
For example
 
telnet 172.16.123.45
 
Prompt is now:
0/tbgw>
*Do command "mv88eMonitor" to get the PortMask and PortNumber:
mv88eMonitor
 
The output should be like this:
Port Mapping:
PortDesc  :                      voip0  voip1 sw6352  fpga  mgmt0  mgmt1  eth0  eth1  host sw6321    cpu
PortNumber :      0      1      2      3      4      5      6      7      8      9    10    11    12    13
PortMask  :    0x1    0x2    0x4    0x8  0x10  0x20  0x40  0x80  0x100  0x200  0x400  0x800 0x1000 0x2000
 
*Use this command to capture VoIP0 traffic (for 600 seconds or 10 minutes):
mv88eMonitor 0x8 0x8 11 600
*Use this command to capture VoIP1 traffic:
mv88eMonitor 0x10 0x10 11 600
 
In the example, the duration is 600 seconds. This will capture traffic for 10 minutes.
 
Note: We do not recommend to keep capturing for a long time. This is only used for debugging purpose.
<br />
<br />
 
'''Step 2'''
 
*Access the SN10500 management interface using SSH<br />
start tbx_cli_tools_remote
[root@TB016635 ~]# tbx_cli_tools_remote
 
*Connect to tbrouter
(The following is displayed:)
Available remote hosts to control (TBX_GW_PORT=12358, local IPs 172.16.0.1 / 172.18.0.1). Press corresponding letter to
control:
    a : TB016634.tbrouter
    b : TB016635.gateway
    c : TB016635.logtrace
    d : TB016635.stream_server
    e : TB016635.tboam_app
    f : TB016635.tbrouter      <------------tbrouter
    g : TB016635.tbsnmpagent
    h : TB016635.tbsyslog
    i : TB016635.tbuctwriter
    j : TB016635.toolpack_engine
    k : TB016635.toolpack_sys_mgr
    l : TB016635.web_server
 
*Select the tbrouter application. (Letter 'f' in the above example)
 
*Once you have access to the tbrouter application, press 'p'
        Capture circular buffer size (nb of packets)?      : 50000  <-- set the number of packets to capture
        Capture mode (1:In 2:Out 4:Monitor) (ex: 3=In+out) : 4      <-- Select 4
        VLAN id (list, -1:All) (ex:151, 152, 153, 154)    : -1
        Convert DSA tags to VLAN tags                      : Yes
        Capture only firewall-protected VLANs              : Yes
 
Press Enter to start the capture.
 
=== Stop Capture ===
Press 'P' (capital letter) to stop the capture.
 
*Access the telecom baseboard from the SN10500 using telnet.
telnet 172.16.123.45
*Stop the capture
mv88eMonitor 0 0 0
 
=== Download Capture ===
To download the voip_capture.cap file, use SSH secure copy ("sftp") to the SN10500 management port. This can be done on Windows using tools like [https://filezilla-project.org/ Filezilla] or [http://winscp.net/ WinSCP].<br />
The file location of the capture is:
/lib/tb/toolpack/tbrouter/pcap
