Usage Guidelines

Usage Scenario

After EMDI detection on video traffic transmitted on a device, to view historical statistics of a specified channel or all channels in the upstream direction, run the display emdi statistics history command. To view historical statistics of a specified channel or all channels in the downstream direction, run the display emdi statistics history outbound command. If the channel-name parameter is specified, historical statistics about the specified channel are displayed. If the parameter is not specified, historical statistics about all channels are displayed. In addition, you can use the start start-indexend end-index parameter to specify the start index and end index of historical records or use the latest-record record-number parameter to specify the number of the latest records to be queried. If these parameters are not specified, all historical records are queried.

Precautions

This command displays statistics about abnormal traffic only, including packet loss, packet out-of-order, jitter, or service interruption. During detection, if all data is displayed as 0 in the display emdi statistics history command output, traffic is interrupted.

Example

The actual command output varies according to the device. The command output here is only an example.
