• During loopback testing, the Ethernet interface operates in full duplex mode. When you disable
loopback testing, the port returns to its duplex setting.
• When a Layer 3 Ethernet interface operates in bridge mode (as a Layer 2 Ethernet interface) or in
promiscuous mode, the interface does not support loopback testing.
2. Configuration procedure
To enable loopback testing on an Ethernet interface:
Ste
p
Command
Remarks
1. Enter system view.
system-view N/A
2. Enter Ethernet interface view.
interface interface-type
interface-number
N/A
3. Enable loopback testing. loopback { external | internal }
By default, loopback testing is
disabled.
Configuring the link mode of an Ethernet interface
Interfaces can operate either as Layer 2 or Layer 3 Ethernet interfaces (you can set the link mode to
bridge or route).
You can configure the link mode in system view or in Ethernet interface view, which produces the same
result. The link mode configuration in system view applies to multiple interfaces, and the link mode
configuration in interface view applies only to the current interface.
1. Configuration restrictions and guidelines
• After you change the link mode of an Ethernet interface, all settings of the Ethernet interface are
restored to their defaults under the new link mode.
• The link mode configuration for an Ethernet interface in system view and in interface view
supersedes each other.
2. Configuration procedure
To change the link mode of the specified Ethernet interfaces in system view:
