Example for Configuring eMDI to Monitor Quality of a Video Surveillance Network

Example for Configuring eMDI to Monitor Quality of a Video Surveillance Network

Networking Requirements

On the video surveillance network shown in Figure 16-7, Switch_1, Switch_2, and Switch_3 need to monitor quality of video streams from IPC_1. The three switches have reachable routes to each other.

Figure 16-7  Networking for configuring eMDI on a video surveillance network

Procedure

  1. Deploy eMDI on Switch_1.

    # Configure an eMDI instance with the ID of 1.

    <HUAWEI> system-view
    [HUAWEI] sysname Switch_1
    [Switch_1] emdi
    [Switch_1-emdi] emdi instance 1
    [Switch_1-emdi-instance-1] flow ipv4 tcp source 10.1.1.1 destination 10.2.2.2 source-port 1 destination-port 2   //Configure the target flow characteristics. Set the source IP address to 10.1.1.1, destination IP address to 10.2.2.2, source port to 1, and destination port to 2.
    [Switch_1-emdi-instance-1] end lifetime seconds 300   //Set the lifetime of eMDI instance 1 to 300 seconds.
    [Switch_1-emdi-instance-1] alarm dplr threshold 1000   //Set the alarm threshold of the downstream packet loss rate to 1000 in eMDI instance 1.
    [Switch_1-emdi-instance-1] start   //Start the eMDI instance.

  2. Deploy eMDI on Switch_2.

    # Configure an eMDI instance with the ID of 1.

    <HUAWEI> system-view
    [HUAWEI] sysname Switch_2
    [Switch_2] emdi
    [Switch_2-emdi] emdi instance 1
    [Switch_2-emdi-instance-1] flow ipv4 tcp source 10.1.1.1 destination 10.2.2.2 source-port 3 destination-port 4   //Configure the target flow characteristics. Set the source IP address to 10.1.1.1, destination IP address to 10.2.2.2, source port to 3, and destination port to 4.
    [Switch_2-emdi-instance-1] end lifetime seconds 300   //Set the lifetime of eMDI instance 1 to 300 seconds.
    [Switch_2-emdi-instance-1] alarm dplr threshold 1000   //Set the alarm threshold of the downstream packet loss rate to 1000 in eMDI instance 1.
    [Switch_2-emdi-instance-1] start   //Start the eMDI instance.

  3. Deploy eMDI on Switch_3.

    # Configure an eMDI instance with the ID of 1.

    <HUAWEI> system-view
    [HUAWEI] sysname Switch_3
    [Switch_3] emdi
    [Switch_3-emdi] emdi instance 1
    [Switch_3-emdi-instance-1] flow ipv4 tcp source 10.1.1.1 destination 10.2.2.2 source-port 5 destination-port 6   //Configure the target flow characteristics. Set the source IP address to 10.1.1.1, destination IP address to 10.2.2.2, source port to 5, and destination port to 6
    [Switch_3-emdi-instance-1] end lifetime seconds 300   //Set the lifetime of eMDI instance 1 to 300 seconds.
    [Switch_3-emdi-instance-1] alarm dplr threshold 1000   //Set the alarm threshold of the downstream packet loss rate to 1000 in eMDI instance 1.
    [Switch_3-emdi-instance-1] start   //Start the eMDI instance.

  4. Verify the configuration.

    The following uses the display on Switch_1 as an example.

    # Run the display emdi command on Switch_1 to check the eMDI specifications and current configuration.

    [Switch_1] display emdi
