/mcu/media/ping_usage/en.png

If you enter an incorrect address in the input field, the output field will display an error from the server.

Using 'traceroute' command

To determine the data packets route in TCP/IP networks and the path length, you can use the 'traceroute' command. To proceed, complete the steps mentioned in the previous command.

/mcu/media/traceroute_usage/en.png

Traffic capture

TrueConf MCU is equipped with a network analysis tool that can capture and save incoming and outgoing data packets. To start capturing, click Start. When you stop log collection, a table with a list of files will be displayed below, indicating the time and file size. You can save the file by clicking /mcu/media/save_icon/en.png and delete it using the /mcu/media/delete_icon/en.png button.

TCP/IP ports

To configure audio and video transmission protocols, go to the TCP/IP ports tab. You can also specify port ranges for the following protocols:

  • BFCP

  • H.245

  • RTP.

This section also enables you to specify the size of RTP packets and select the ports for SIP and H.323 connections.

You can set up the priority of data streams according to the DSCP (opens new window) protocols:

/mcu/media/qos_usage/en.png
  • DSCP audio is for audio traffic

  • DSCP video is for video traffic

  • DSCP other is for other traffic, e.g. remote PTZ camera control.

The larger number you set, the higher priority will be given to the selected type of transmitted packets.

Network interfaces

To access settings in this tab, you will need to install the NetworkManager package.

Select the version of Linux to download the installation package:

After downloading the package, run the following terminal command to install it:

apt install -y ./network_manager_debian9.deb

On the Network interfaces tab, you can check the server system name and its MAC address. It is also possible select an IP addressing mode (static or DHCP). If the static mode is selected, the following parameters have to be specified:

  • IP address

  • Subnet mask

  • Gateway

  • Primary DNS server

  • Secondary DNS server.

Video

In this section you can configure video encoding and storage settings:

/mcu/media/mcu_video/en.png
  1. Set the maximum size of media file storage

  2. Select an encoding profile for the primary video stream

  3. Select an encoding profile for the secondary video stream

  4. Set the bandwidth for the secondary video stream (will be calculated as the percent of the total bandwidth allocated for both primary and secondary streams)

  5. Set the time interval for shuffling or alternating participants in the video window (available only when selecting a layout supporting shuffling).

  6. Select a video scaling mode for layout windows

  7. Enable/disable avatar display in the fixed layout window (will be displayed if a participant has not yet joined the conference or has turned off the camera)
