The huawei S2300’s interface protocol become `–`

        The huawei S2300's interface protocol become <code>--</code>:

The normal interface should like this:

Vlanif2                     up       up          --     --          0   
You see the GigabitEthernet and Vlanif all are right, but the Ethernet port has issue. my Switch problem is Ethernet switch port become --.
