Capturing using the internal host of the TSBC-HW unit
The internal host of the TSBC-HW 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:
Step 1
- Access the TSBC-HW 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.
Step 2
- Access the TSBC-HW management interface using SSH
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 TSBC-HW 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 TSBC-HW management port. This can be done on Windows using tools like Filezilla or WinSCP.
The file location of the capture is:
/lib/tb/toolpack/tbrouter/pcap
