Systems and methods for integrating wireless local area networks on extended bridges

1. An information handling system, comprising:

a first controlling bridge including one or more bridge ports;

a first port extender comprising a first extended port and coupled to one of the bridge ports of the first controlling bridge; and

a wireless access point coupled to the first extended port, the first extended port and the wireless access point forming a first logical bridge port of the first controlling bridge;

wherein the first controlling bridge, the first port extender, and the wireless access point appear as an integrated extended service set (ESS).

2. The information handling system of claim 1 , further comprising:

a second access point; and

a second port extender coupled to the first controlling bridge, the second port extender including a second extended port coupled to the second access point.

3. The information handling system of claim 2 , wherein the first controlling bridge and the second port extender are coupled such that the second extended port of the second port extender provide a second logical bridge port.

4. The information handling system of claim 1 , wherein the first extended port and the wireless access point appear to a first wired station coupled to the first controlling bridge as the first logical bridge port on the first controlling bridge.

5. The information handling system of claim 4 , wherein the first extended port and the wireless access point appear as the first logical bridge port on the first controlling bridge by tagging frames transmitted within the information handling system.

6. The information handling system of claim 5 , wherein the frames are tagged according to the 802.1BR standard.

7. The information handling system of claim 1 , further comprising a second controlling bridge coupled to the first controlling bridge by an interconnect link, the first and second controlling bridges forming a virtual link trunk (VLT).

8. The information handling system of claim 1 , further comprising an access controller coupled to the first controlling bridge and configured to enforce policies of the information handling system.

9. A method of providing wireless network access to a local area network (LAN), the method comprising:

receiving a request to join the LAN from a station at an access point in the LAN;

communicating the request from the access point to a first controlling bridge of an extended bridge through a first port extender, the first port extender comprising a first extended port, wherein the first extended port and the access point form a first logical port of the first controlling bridge;

communicating the request from the first controlling bridge to an access controller;

granting, by the access controller, the request from the station; and

receiving frames from the station on the first logical port of the first controlling bridge;

wherein the first controlling bridge, the first port extender, and the access point appear as an integrated extended service set (ESS).

10. The method of claim 9 , wherein receiving the request from the access point comprises receiving an identifier of the station and receiving a credential from the station.

11. The method of claim 9 , further comprising communicating, by the access controller, an identifier and a credential of the station to an authentication, authorization, and accounting (AAA) server.

12. The method of claim 9 , wherein the frames received on the first logical port of the first controlling bridge appear to the access controller as if received on a physical port of the first controlling bridge.

13. The method of claim 9 , further comprising implementing, by the access controller, a policy to restrict access to the LAN based on one or more of an identity of a user, an identity of a device, or an identity of a type of device.

14. The method of claim 9 , further comprising identifying a tag included in each of the frames, wherein the tag identifies the first logical port of the first controlling bridge on which a respective frame was received.

15. A method of providing wireless network access to a local area network (LAN), the method comprising:

receiving a frame at a first controlling bridge, the first controlling bridge being coupled to a first port extender by a bridge port, the first port extender providing a first extended port that functions as a logical port on the first controlling bridge;

identifying, by the first controlling bridge, a tag in the frame that identifies the logical port on the first controlling bridge;

transmitting, by the first controlling bridge, the frame to the logical port on the first controlling bridge;

forwarding the frame to a first access point coupled to the first extended port, the first access point appearing to an access controller coupled to the first controlling bridge as a wireless port; and

wirelessly transmitting the frame from the first access point to a station;

wherein the first controlling bridge, the first port extender, and the first access point appear as an integrated extended service set (ESS) to the station.

16. The method of claim 15 , wherein the frame is tagged according to the 802.1BR standard.

17. The method of claim 15 , wherein the first controlling bridge is coupled to a second port extender, and wherein identifying the tag indicates to which of the first port extender and the second port extender the frame should be transmitted.

18. The method of claim 15 , wherein the first port extender is coupled to an additional port extender, such that the first access point is coupled to the first controlling bridge through the first port extender and the additional port extender.

19. The method of claim 15 , wherein the first controlling bridge is coupled to a second controlling bridge by an interconnect link, the first and second controlling bridges forming a virtual link trunk (VLT).

20. The method of claim 19 , further comprising, when the first controlling bridge fails, activating the second controlling bridge, wherein the second controlling bridge, a second port extender coupled to the second controlling bridge, and a second access point coupled to the second port extender appear as a second integrated ESS to the station.
