Command to find interfering SSIDs seen by a Access Point.

[rhallan]

New CISCO WLAN user.....

When troubleshooting home based users with Teleworker APs I want to see what other networks are in the users home or nearby i.e. to see what SSIDs are interfering and on same channel as their AP.

Is there a command in CLI or other method to do this ?

For Aruba/HP there is command show ap monitor ap-list

You need a tool to look at RF environment. Give it a trial with below product & see you could see what networks are there & how much they will interfere with your wifi

Thanks. For tools like this you have to be on site.
I would need to look for interfering SSIDs remotely.

The command is "sh rogue ap summary".

Thanks for your reply.

So I tried this on a Campus AP and I do see the rogues but there is no SSID name information the rogues are broadcasting, just the mac addresses. Is there a way to get the SSID information ?

Secondly, the main issue is that I am trying to do this for Teleworker/OfficeExtend AIR-AP1815T-A-K9.

It appears I am not able to enable rogue detection on these APs, but I can do on other Campus APs. The check box to enable rogue detection is grayed out (see picture) for OfficeExtend APs.

I do have rogue location discovery protocol enabled under Security>Wireless Protection Policies>Rogue Policies>General.

Software Version is 8.7.106.0

Trying to see if/how to enable rogue detection on OfficeExtend.

So if you get the MAC address, enter the command "sh rogue ap detail <MAC address>".

If you want to enable that feature, it needs to be done when converting AP into OEAP mode. Pls see below deployment guide

https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-4/b_AP_1815_wall_plate_deployment_guide.html

It is recommend to disable it as in home environment you always expect to see other APs, When you enable this feature, AP has to go off channel to detect those rouges & that impact time it needs to service clients. Given home environment you will see rogue always, no any value addition detecting them. Office environment is different where you should not see that many rogues & you want to know if any doing that.

See below document to see how rogue detection works

https://www.cisco.com/c/en/us/support/docs/wireless-mobility/wireless-lan-wlan/70987-rogue-detect.html

Also note that these 18xx series AP is not feature parity with other enterprise Cisco AP models. "Clean Air" is a main feature lacking of these AP models. That feature helps to detect non-wifi interference. Those 18xx model got a feature called spectrum intelligence which is a very basic interference detecion capability which cannot compared with clean air. Pls see below for more details.
