The present invention adopts logical circuit directly to obtain port information from the MAC of chip, and it is wider relatively to use the physical port PHY of the network equipment to obtain the method range of application of port information.The present invention controls indicator light according to the port status of chip MAC and shows, does not need CPU to participate in, and has effectively improved the indicator light speed of displaying, has reduced the time that takies CPU.
Description of drawings
Fig. 1 is that the present invention obtains the schematic flow sheet with display network device port state;
Fig. 2 is the electrical block diagram of indication network device port state of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further details, but not as limitation of the present invention.
As shown in Figure 1, be that the present invention obtains the schematic flow sheet with display network device port state, comprising:
Step 1, in init state, the IO mouth of all programmable logical device of Ethernet data plate output high level, at this moment, each port LED light of database is gone out.
Step 2, programmable logic device obtain the mac state of port from exchange chip by clock bus and data/address bus.
Step 3, programmable logic device connect (LINK) state according to the port that obtains, and by the different level of IO mouth output, connect the indication of (LINK) state.Activity (ACTIVE) state according to port carries out the indication of activity (ACTIVE) state.
Step 4, programmable logic device do not stop repeating step two and step 3, regularly obtain the state of port from MAC, and carry out the indicator light demonstration according to port status.
As shown in Figure 2, be the electrical block diagram of indication network device port state of the present invention.In an embodiment, programmable logic device obtains the LINK state and the ACTIVE state of port by clock bus and data/address bus from media access controller (MAC).Programmable logic device carries out the LINK state indication of port according to the LINK state of port, carry out the ACTIVE state indication of port according to port ACTIVE state, when port LINK state just often, the IO pin output low level of programmable logic device, the LINK status indicator lamp is bright, and expression port LINK state is normal, when port LINK state is abnormal, the IO pin output high level of programmable logic device, the LINK status indicator lamp goes out.When port was receiving or sending message (being in active state), the IO pin of programmable logic device was alternately exported high level and low level, ACTIVE indicator light flicker, and port stops to receive and when sending message, the ACTIVE indicator light goes out.
It will be apparent to those skilled in that LINK state and ACTIVE state can be indicated by an indicating device, also can indicate by two indicating devices.
Indicating device can light-emitting diode.
The bright expression of indicator light LINK state is normal, also can adopt indicator light to go out and represent that the LINK state is normal.
Indicating means for light-emitting diode just illustrates here, though present data equipment uses light-emitting diode to indicate, the present invention does not get rid of other indicating means.
Obtain the method for the state of network equipment port MAC, be so in one embodiment: clock bus provides clock signal, transmit port informations such as port LINK, Active, duplexing speed on the data/address bus, logical device obtains the various information of port according to clock signal from data/address bus, logical device also customizes the state indication that the indicator light display packing that needs is carried out port.
In another embodiment, logical device obtains port status information by the port mac status register of accesses network equipment.
Thereby the invention provides a kind of programmable logic device and obtain the method that port status information realizes the indication of ethernet port state, satisfy the indicator light needs of different user, can expand flexibly simultaneously from MAC.
Adopt device of the present invention, solved ethernet device and carried out indicator light demonstration problem flexibly, satisfy various needs.Simultaneously, because CPU can not participate in the process of lighting a lamp, not only the reaction of indicator light is timely, and it is shorter to delay time, and has reduced cpu busy percentage, improves software work efficient.
The present invention cooperates powering on of control Ethernet interface by logic and software, thereby realizes Ethernet interface is controlled the opportunity of powering on.But the present invention is equally applicable to simple data equipment carries out electric control on the Ethernet interface by methods such as logical time delay situation.
