Abstract

Method and system for configuring a port of a network device are provided. One method for a port of a network device communicating with another network device port includes reading manufacturing, license and user provided port configuration data by a processor of the network device; obtaining capabilities information for the port by the processor of the network device from an external pluggable media device; setting port configuration data based on the capabilities information obtained from the external pluggable media; executing auto-negotiation on the port, when enabled and obtaining configuration data from the other port; determining that enough data is available to set port configuration; attempting to configure the port by using a highest permissible bandwidth configuration when enough data is available to set the port configuration; and setting port configuration based on the attempt to configure the port to operate when a link connected to the port is operational.

Claims (43)

1. A machine-implemented method for a port of a network device communicating with another network device port, the method comprising:

reading manufacturing, license and user provided port configuration data by a processor of the network device;

obtaining capabilities information for the port by the processor of the network device from an external pluggable media device, when the external pluggable media device is present;

setting port configuration data based on the capabilities information obtained from the external pluggable media;

executing auto-negotiation on the port, when enabled and obtaining configuration data from the other port;

determining that enough data is available to set port configuration;

attempting to configure the port by using a highest permissible bandwidth configuration when enough data is available to set the port configuration; and

setting port configuration based on the attempt to configure the port to operate when a link connected to the port is operational.

2. The method of claim 1 , wherein the external pluggable media is provided via a connection or slot of the network device.

3. The method of claim 1 , wherein the external pluggable media device stores an operating link rate and a protocol used for communication.

4. The method of claim 1 , wherein the external pluggable media device is a small factor pluggable (SFP) transceiver that is coupled on one side to the port of the network device and on another side to a networking cable or a Fibre.

5. The method of claim 1 , wherein a link rate and a protocol type are used to set the port configuration.

6. The method of claim 1 , wherein when the link is not operational, selecting a next highest available bandwidth and attempting to configure the port to operate by using the next highest available bandwidth.

7. A non-transitory, machine readable storage medium having stored thereon instructions for performing a method for a port of a network device communicating with another network device port, comprising machine executable code which when executed by at least one machine, causes the machine to:

read manufacturing, license and user provided port configuration data by a processor of the network device;

obtain capabilities information for the port by the processor of the network device from an external pluggable media device, when the external pluggable media device is present;

set port configuration data based on the capabilities information obtained from the external pluggable media;

execute auto-negotiation on the port, when enabled and obtaining configuration data from the other port;

determine that enough data is available to set port configuration;

attempt to configure the port by using a highest permissible bandwidth configuration when enough data is available to set the port configuration; and

set port configuration based on the attempt to configure the port to operate when a link connected to the port is operational.

8. The storage medium of claim 7 , wherein the external pluggable media is provided via a connection or slot of the network device.

9. The storage medium of claim 7 , wherein the external pluggable media device stores an operating link rate and a protocol used for communication.

10. The storage medium of claim 7 , wherein the external pluggable media device is a small factor pluggable (SFP) transceiver that is coupled on one side to the port of the network device and on another side to a networking cable or a Fibre.

11. The storage medium of claim 7 , wherein a link rate and a protocol type are used to set the port configuration.

12. The storage medium of claim 7 , wherein when the link is not operational, selecting a next highest available bandwidth and attempting to configure the port to operate by using the next highest available bandwidth.

13. A network device, comprising:

a port communicating with another port of another network device; and

a processor executing machine executable instructions to:

read manufacturing, license and user provided port configuration data;

obtain capabilities information for the port from an external pluggable media device, when the external pluggable media device is present;

set port configuration data based on the capabilities information obtained from the external pluggable media;

execute auto-negotiation on the port, when enabled and obtaining configuration data from the other port;

determine that enough data is available to set port configuration;

attempt to configure the port by using a highest permissible bandwidth configuration when enough data is available to set the port configuration; and

set port configuration based on the attempt to configure the port to operate when a link connected to the port is operational.

14. The network device of claim 13 , wherein the external pluggable media is provided via a connection or slot of the network device.

15. The network device of claim 13 , wherein the external pluggable media device stores an operating link rate and a protocol used for communication.

16. The network device of claim 13 , wherein the external pluggable media device is a small factor pluggable (SFP) transceiver that is coupled on one side to the port of the network device and on another side to a networking cable or a Fibre.

17. The network device of claim 13 , wherein a link rate and a protocol type are sufficient to set the port configuration.

18. The network device of claim 13 , wherein when the link is not operational, selecting a next highest available bandwidth and attempting to configure the port to operate by using the next highest available bandwidth.

19. The network device of claim 13 , wherein the network device is a switch element.

20. The network device of claim 13 , wherein the network device is a network adapter.
