Abstract

An information handling system for managing a network includes a first stackable network switch, a second stackable network switch, and a hardware switching management controller. The first stackable network switch includes a first configuration setting to enable the first stackable network switch to operate in a switch stack. The first configuration setting is accessible via an OpenFlow protocol. The second stackable network switch includes a second configuration setting to enable the second stackable network switch to operate in the switch stack. The second configuration setting is accessible via the OpenFlow protocol. The hardware switching management controller includes an OpenFlow stacking manager configured to set the first configuration setting and the second configuration setting such that the switch stack includes the first and second stackable network switches.

Claims (34)

1. An information handling system for managing a network, the information handling system comprising:

a first stackable network switch including a first configuration setting that configures the first stackable network switch to operate in a switch stack, wherein the first configuration setting is accessible via an OpenFlow protocol;

a second stackable network switch including a second configuration setting that configures the second stackable network switch to operate in the switch stack, wherein the second configuration setting is accessible via the OpenFlow protocol; and

a hardware switching management controller, wherein the switching management controller sets the first configuration setting and the second configuration setting such that the switch stack includes the first and second stackable network switches, and wherein in setting the first configuration setting, the switching management controller sends an OpenFlow stacking status request to the first stackable network switch.

2. The information handling system of claim 1 , wherein in setting the first configuration setting, the switching management controller sends an OpenFlow feature request to the first stackable network switch.

3. The information handling system of claim 2 , wherein in response to the OpenFlow feature request the first network switch responds with an OpenFlow feature reply that indicates that the first stackable network switch includes the first configuration setting.

4. The information handling system of claim 1 , wherein in response to the OpenFlow stacking status request the first network switch responds with an OpenFlow stacking status reply that indicates a condition of the switch stack.

5. The information handling system of claim 1 , wherein the first and second stackable network switches are from a common vendor.

6. The information handling system of claim 1 , wherein the first and second stackable network switches are from different vendors.

7. A method for managing a network, the method comprising:

configuring a hardware switching management controller to instantiate an OpenFlow switching manager;

setting, by the OpenFlow switching manager, a first configuration setting of a first stackable network switch, the first configuration setting to enable the first stackable network switch to operate in a switch stack, wherein the first configuration setting is accessible via an OpenFlow protocol; and

setting a second configuration setting of a second stackable network switch, the second configuration setting to enable the second stackable network switch to operate in the switch stack, wherein the second configuration setting is accessible via the OpenFlow protocol, wherein in setting the first configuration setting, the method further comprises;

sending, by the OpenFlow switching manager, an OpenFlow port modify command to the first stackable network switch, the OpenFlow port modify command enabling the first stackable network switch to operate in the switch stack, and identifying the second stackable network switch as a member of the switch stack.

8. The method of claim 7 , wherein, in setting the first configuration setting, the method further comprises:

sending, by the OpenFlow switching manager, an OpenFlow feature request to the first stackable network switch.

9. The method of claim 8 , wherein, in response to the OpenFlow feature request, the method further comprises:

responding, by the first network switch, with an OpenFlow feature reply that indicates that the first stackable network switch includes the first configuration setting.

10. The method of claim 7 , wherein, in response to the OpenFlow port modify command, the method further comprises:

responding, by the first network switch, with an OpenFlow port status reply that indicates that the first stackable network switch is enabled to operate in the switch stack and that the second stackable network switch is a member of the switch stack.

11. The method of claim 7 , wherein the first and second stackable network switches are from a common vendor.

12. The method of claim 7 , wherein the first and second stackable network switches are from different vendors.

13. An information handling system for managing a network, the information handling system comprising:

a first stackable network switch including a first configuration setting to enable the stackable network switch to operate in a switch stack and a second configuration setting to configure a port of the stackable network switch,

wherein the first configuration setting is accessible via an OpenFlow protocol and

wherein the second configuration setting is accessible via an OpenFlow Management and Configuration (OF-Config) protocol;

a first hardware switching management controller,

wherein the first hardware switching management controller sets the first configuration setting such that the switch stack includes the stackable network switch,

wherein in setting the first configuration setting, the first switching management controller further sends an OpenFlow port modify command to the first stackable network switch the OpenFlow port modify command enabling the first stackable network switch to operate in the switch stack identifying a second stackable network switch as a member of the switch stack a second hardware switching management controller

wherein the second switching management controller sets the second configuration setting.

14. The information handling system of claim 13 , wherein, in response to an OpenFlow port modify command, the first stackable network switch further responds with an OpenFlow port status reply that indicates that the stackable network switch is enabled to operate in the switch stack.

15. The information handling system of claim 13 , wherein in setting the first configuration setting, the switching management controller further sends an OpenFlow feature request to the first stackable network switch.

16. The information handling system of claim 15 , wherein in response to the OpenFlow feature request the first stackable network switch further responds with an OpenFlow feature reply that indicates that the first stackable network switch includes the first configuration setting.

17. The information handling system of claim 13 , wherein in response to the OpenFlow port modify command the first stackable network switch further responds with an OpenFlow port status reply that indicates that the first stackable network switch is enabled to operate in the switch stack and that the second stackable network switch is a member of the switch stack.
