Usage Guidelines

Usage Scenario

After BDs are configured on a device, to view BD information, run the display bridge-domain command. The command output contains bridge domain configurations, including which EVC Layer 2 sub-interfaces are added to a BD. The command output helps verify the configuration and analyze faults.

Example

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