The state of this entry. When the swDevCtrlTableLockState object is enabled, the state is not changed. When swVlanInfoStatus is in MAC-Base VLAN mode, this object is always disabled.The meanings of the values are: other(1) - this entry is currently in use but the conditions under which it will remain so are different from each of the following values. disable(2) - Port lock funtion disable. enable(3) - Locking a port. Once the port is locked, it will not learn new SA addresses, and drop unknown/moved-SA packets forwarding to/from such ports. This is a way to prevent undesired traffic from being received or transmmited on the port. Note that locking a port doesn't lock the MAC address entries associated with the locked port, i.e. the existing address entries of the locked port will be age out even though it is locked.
