This section describes how to monitor the EVC operating status.
In routine maintenance, you can run the following command in any view to view the EVC operating status.
Before you run the display bridge-domain statistics command to view VLAN packet statistics and locate faults, run the statistic enable command in the specific BD view to enable the device to collect VLAN packet statistics. If the device is disabled from collecting VLAN packet statistics, you cannot obtain the statistics.
Before you run the display bridge-domain statistics command to check statistics about discarded BUM packets in a BD for fault locating, run the statistic discard enable command in the BD view to enable collection on traffic statistics about discarded BUM packets. If you do not run the statistics discard enable command, the statistics cannot be collected.
Before running the display ethernet uni statistics command, you must run the statistic enable mode multiple command in the EVC Layer 2 sub-interface view to enable the traffic statistics function in multiple mode.
Run the reset ethernet uni statistics command to clear the existing statistics if you want to collect traffic statistics again.
