NOTE:
•
The router does not support the loopback external command.
• As for internal loopback testing and external loopback testing, if an interface is down, only the former
is available on it; if the interface is shut down, both are unavailable.
• The speed, duplex, mdi, combo enable, and shutdown commands are not applicable during
loopback test.
• With loopback test enabled, the Ethernet interface operates in full duplex mode. With loopback test
disabled, the original configurations will be restored.
• After configuring the loopback internal command and then the undo loopback command on an
Ethernet interface, you should re-enable the interface with the shutdown command and then the undo
shutdown command to trigger an auto-negotiation on the interface.
Setting the interval for collecting Ethernet interface statistics
To configure the interval for collecting interface statistics:
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure the interval for
collecting interface statistics.
flow-interval interval
Optional
The default setting is 300 seconds.
Configuring the link mode of an Ethernet interface
Depending on the layer (data link layer or network layer) at which the device processes the packets
received on an interface, an interface can be as a Layer 2 Ethernet interface (in bridge mode) or as a
Layer 3 Ethernet interface (in route mode). You can configure an Ethernet interface as a Layer 2 Ethernet
interface or Layer 3 Ethernet interface by setting the link mode to bridge or route.
To change the link mode of an Ethernet interface:
Step Command Remarks
1. Enter system view. system-view N/A
2. Change the link mode of
Ethernet interfaces.
• (Approach I) In system view:
port link-mode { bridge |
route } interface-list
• (Approach II) In Ethernet
interface view:
a. interface interface-type
interface-number
b. port link-mode { bridge |
route }
Use either approach.
By default, Ethernet interfaces work
in route mode.
