1.4 Display and Debug Ethernet Port
After the above configuration, execute display command in any view to display the
running of the Ethernet port configuration, and to verify the effect of the configuration.
Execute reset command in user view to clear the statistics information of the port.
Execute loopback command in Ethernet port view to check whether the Ethernet port
works normally. In the process of the loopback test, the port cannot forward the packets.
The loop test will finish automatically after being executed for a while.
Table 1-15 Display and debug Ethernet port
Operation Command
Configure to perform loopback test
on the Ethernet port.
loopback { external | internal }
Display all the information of the
port
display interface { interface_type |
interface_type interface_num |
interface_name
}
Display hybrid port or trunk port display port { hybrid | trunk }
Display the state of loopback
detection on the port.
display loopback-detection
Clear the statistics information of
the port
reset counters interface [ interface_type |
interface_type interface_num |
interface_name
]
Note that the loopback test cannot be performed on the port disabled by the shutdown
command. During the loopback test, the system will disable speed , duplex , mdi and
shutdown operation on the port. Some ports do not support the loopback test. If
performing this command in these ports, you will see the system prompt.
1.5 Ethernet Port Configuration Example
I. Networking requirements
Ethernet Switch (Switch A) is connected to the peer (Switch B) via the trunk port
Ethernet0/18. The following example configures the default VLAN ID for the trunk port
and verifies the port trunk pvid vlan command. As a typical application of the port
trunk pvid vlan command, the trunk port will transmit the packets without tag to the
default VLAN.
