| − | == 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.

| + | |
| − | 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

| + | |
| − | | + | |
| − | *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

| − | | + | |
| − | === 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 />
