| == 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: <br />
| |
| | |
| '''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.
| |
| <br />
| |

| |
| | |
| '''Step 2'''
| |
| | |
| *Access the TSBC-HW 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 TSBC-HW using telnet.
| |
| telnet 172.16.123.45
| |
| *Stop the capture

| |
| | |
| === 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 [https://filezilla-project.org/ Filezilla] or [http://winscp.net/ WinSCP].<br />
| |
| The file location of the capture is:
| |
| /lib/tb/toolpack/tbrouter/pcap
