mdi { across | auto | normal }
Optional
Defaults to auto. That is, the
Ethernet port automatically detects
the type of the cable in use.
10 GE port cannot support mdi configuration.
Testing the Cable on an Ethernet Port
A link in the up state goes down and then up automatically if you perform the operation described in this
section on one of the Ethernet ports forming the link.
You can enable the test on the cable connected with an Ethernet port to check:
z
Whether the RX and TX of the cable are short-circuited.
z
Whether the cable is open circuited.
z
The length of the faulty cable if there is any fault.
The system will return the check result in 5 seconds.
Follow these steps to test the current operating state of the cable connected to an Ethernet port:

Configuring the Storm Constrain Function on an Ethernet Port
The storm constrain function suppresses packet storm in an Ethernet. With this function enabled on a
port, the system detects the unicast traffic, multicast traffic, or broadcast traffic passing through the port
periodically and takes corresponding actions (that is, blocking or shutting down the port and sending
trap messages and logs) if the traffic detected exceeds the threshold.
