Abstract

A method and apparatus for automatically configuring a network switch having external network data ports, a processor, and memory. Network data is monitored on the external network data port. Information about the network data traffic is compared to one or more threshold conditions. The network switch is automatically configured if the network data meets one of the threshold conditions. The monitor and configuration functions can be performed by software running on the processor which has been downloaded from an external network maintenance station through a maintenance data port. Information about the network data traffic can be uploaded to the external network maintenance station through a maintenance data port.

Claims

1. A network apparatus comprising:

an external network data port;

a network data monitor to monitor network data traffic over the external network data port, the network data monitor includes a memory and a set of monitor program instructions stored in the memory;

a maintenance data port;

a processor coupled to the maintenance data port and in communication with the network data monitor, the processor to execute the set of monitor program instructions and to evaluate the network data traffic, the set of monitor program instructions comprises program instructions transferred to the memory through the maintenance data port; and

a network configuator in communication with the processor, the network configuator to automatically configure the network apparatus to permit a selected flow of network data though the external network data port in response to instructions received from the processor.

2. The network apparatus of claim 1, wherein the memory of the network data monitor is coupled to the processor to store data and the set of monitor program instructions.

3. The network apparatus of claim 1, wherein the maintenance data port is coupled to an external network maintenance station.

4. The network apparatus of claim 1, wherein the network configuator comprises a set of network configuator program instructions stored in the memory and executed by the processor.

5. The network apparatus of claim 4 wherein the set of network configuator program instructions comprises program instructions transferred to the memory through the maintenance data port from an external network maintenance station.

6. The network apparatus of claim 1, wherein the processor transfers information relating to network data traffic through the maintenance data port to an external network maintenance station.

7. A method for configuring a network switch including a maintenance data port, processor and memory, the method comprising:

monitoring network data traffic;

comparing the network data traffic to a threshold condition; and

automatically configuring the network switch if the network data traffic meets the threshold condition by transferring a set of network configuator program instructions to the memory through the maintenance data port.

8. The method of claim 7, wherein prior to monitoring the network data traffic, the method further comprises transferring a set of monitor program instructions to the memory through the maintenance data port from an external network maintenance station.

9. The method of claim 7, wherein the set of network configuators program instructions are transferred from an external network maintenance station.

10. The method of claim 7 further comprising transferring monitor information about the network data traffic to an external network maintenance station through the maintenance data port.

11. The method of claim 7 wherein automatically configuring of the network switch comprises configuring the network switch in response to instructions received from the processor.

12. The method of claim 7 wherein automatically configuring of the network switch comprises configuring the network switch in response to instructions received from an external network maintenance station through the maintenance data port.

13. A network apparatus comprising:

a maintenance data port to receive a first set of byte codes;

a java virtual machine configured to receive the first set of byte codes and to convert the first set of byte codes into a first set of instructions;

a memory in communication with the java virtual machine, the memory to be loaded with (i) the first set of instructions to monitor a flow of network data, and (ii) a second set of instructions to automatically configure the flow of network data; and

a processor coupled to the memory, the processor to execute the first set of instructions and the second set of instructions.

14. The network apparatus of claim 13, wherein the maintenance data port receives the first set of byte codes from a network maintenance station.

15. The network apparatus of claim 13 further comprising:

an external network data port.

16. The network apparatus of claim 15, wherein the flow of network data is monitored at the external network data port.

17. The network apparatus of claim 13, wherein the maintenance data port receives the set of byte codes from a network maintenance station.
