Abstract

According to one embodiment, a particular network device that comprises at least one hardware processor is described. The network device is configured to perform operations including operating in a first mode by communicating wirelessly with at least one wireless client device to provide the at least one wireless client device access to one or more resources, where the operating in the first mode comprises receiving packets transmitted by the at least one wireless client device and forwarding the packets to the one or more resources. Furthermore, the network device performs operations, including switching from operating in the first mode to operating in a monitoring mode and operating in the monitoring mode by decoding data packets addressed to network devices other than the particular network device.

Claims

1. A non-transitory computer readable medium comprising instructions which, when executed by one or more hardware processors, causes the one or more hard processors to:

operate a particular network device in a first mode, wherein in the first mode, the particular network device is to communicate wirelessly with at least one wireless client device to provide the at least one wireless client device access to one or more resources, receive packets transmitted by the at least one wireless client device and forward the packets to the one or more resources;

switch the particular network device from operating in the first mode to operating in a second mode; and

operate the particular network device in the second mode, wherein in the second mode, the particular network device is to (a) identify a second network device within a radio frequency range from the particular network device based on the particular network device monitoring data packets transmitted by the second network device to one of the network devices other than the particular network device and (b) report information related to the second network device.

2. The non-transitory computer readable medium of claim 1, wherein the particular network device does not provide access to the one or more resources to any wireless client device while operating in the second mode.

3. The non-transitory computer readable medium of claim 1, wherein in the second mode, the particular network device is to receive a first portion of the data packets on a first radio frequency channel and a second portion of the data packets on a second radio frequency channel that is different than the first radio frequency channel.

4. The non-transitory computer readable medium of claim 1, wherein in the second mode, the particular network device is to identify and report at least one network device that is (a) operating within a radio frequency range from the particular network device and (b) not addressing any data packets to the particular network device.

5. A particular network device comprising:

at least one hardware processor; and

a non-transitory computer readable storing instructions that when executed by the at least one hardware processor cause the at least one hardware processor to;

operate in a first mode, wherein in the first mode, the at least one hardware processor is to communicate wirelessly with at least one wireless client device to provide the at least one wireless client device access to one or more resources, receive packets transmitted by the at least one wireless client device and forward the packets to the one or more resources;

switch from operating in the first mode to operating in a second mode; and

operate operating in the second mode, wherein in the second mode, the at least one hardware processor is to (a) identify a second network device within a radio frequency range from the particular network device based on the particular network device monitoring data packets transmitted by the second network device to one of the network devices other than the particular network device and (b) report information related to the second network device.

6. The particular network device of claim 5, wherein the at least one hardware processor does not provide access to the one or more resources to any wireless client device while operating in the second mode.

7. The particular network device of claim 5, wherein, in the second mode, the at least one hardware processor is to receive a first portion of the data packets on a first radio frequency channel and a second portion of the data packets on a second radio frequency channel that is different than the first radio frequency channel.

8. The particular network device of claim 5, wherein in the second mode, the at least one hardware processor is to identify and report at least one network device that is (a) operating within a radio frequency range from the particular network device and (b) not addressing any data packets to the particular network device.

9. A non-transitory computer readable medium comprising instructions which, when executed by one or more hardware processors, cause the one or more hardware processors to:

operate a particular network device in a first mode, wherein in the first mode, the particular network device is to communicate wirelessly with at least one wireless client device to provide the at least one wireless client device access to one or more resources, receive packets transmitted by the at least one wireless client device and forward the packets to the one or more resources;

switch the particular network device from operating in the first mode to operating in a monitoring mode; and

operate the particular network device in the monitoring mode, wherein in the monitoring mode, the particular network device is to monitor packets on a plurality of radio frequency channels and report information associated with the packets detected on the plurality of radio frequency channels, and

wherein in the monitoring mode, the particular network device is to (a) identify a second network device within a radio frequency range from the particular network device based on the particular network device monitoring data packets transmitted by the second network device to one of the network devices other than the particular network device and (b) report information related to the second network device.

10. The non-transitory computer readable medium of claim 9, wherein the particular network device does not provide access to the one or more resources to any wireless client device while operating in the monitoring mode.

11. The non-transitory computer readable medium of claim 9, wherein operating in the monitoring mode comprises decoding data packets not addressed to the particular network device.

12. The non-transitory computer readable medium of claim 9, wherein in the monitoring mode, the one or more hardware processors are further to identify and report at least one network device that is (a) operating within a radio frequency range from the particular network device and (b) not addressing any data packets to the particular network device.

13. A method comprising:

operating a particular network device in a first mode, including communicating wirelessly with at least one wireless client device to provide the at least one wireless client device access to one or more resources, receiving packets transmitted by the at least one wireless client device and forwarding the packets to the one or more resources;

switching the particular network device from operating in the first mode to operating in a second mode; and

operating the particular network device in the second mode, including the particular network device identifying a second network device within a radio frequency range from the particular network device based on the particular network device monitoring data packets transmitted by the second network device to one of the network devices other than the particular network device and reporting information related to the second network device.

14. The method of claim 13, further comprising:

preventing, by the particular network device, any wireless client device from accessing the one or more resources while the particular network device is operating in the second mode.

15. The method of claim 13, further comprising:

in the second mode, receiving, by the particular network device, a first portion of the data packets on a first radio frequency channel and a second portion of the data packets on a second radio frequency channel that is different than the first radio frequency channel.

16. The method of claim 13, further comprising:

in the second mode, identifying and reporting, by the particular network device, at least one network device that is (a) operating within a radio frequency range from the particular network device and (b) not addressing any data packets to the particular network device.
