__NOTOC__ === '''''Applies to version(s): v3.0''''' === {{DISPLAYTITLE:VoIP Ethernet Capture TSBC-HW}} == 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 /> <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 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 [https://filezilla-project.org/ Filezilla] or [http://winscp.net/ WinSCP].<br /> The file location of the capture is: /lib/tb/toolpack/tbrouter/pcap == References == *[[VoIP_Ethernet_Capture|VoIP Ethernet Capture]] *[[VoIP Ethernet Capture FreeSBC A|FreeSBC VoIP Ethernet Capture]]
