Sniffer mode bssid

JustTakeTheFirstStep — Fri, 02 Jun 2023 02:20:27 GMT

I set the AP in sniffer mode.

As far as I know, sniffer mode does not broadcast beacon frames.

But in controller show ap wlan summary I see bssid.

Can you tell me why?

I guess it is due to AP got those profiles/tag assigned, in CLI that output displayed. But it should not broadcast any beacons if you put AP into sniffer mode.

Did you check taking a packet capture to see any beacons goes over the air

Hi
When wlan is disabled, bssid can be seen with "show ap wlan summary" command

Thank you

As @Rasika Nayanajith mentioned, that "show ap wlan summary" command in the WLC shows the BSSID that has been assigned to the AP, but to check if the BSSIDs are been broadcasted or not you need to go to the AP's CLI and check with "show controllers dot11Radio [0|1] wlan" and see if the "radio/vap/ids" are there, or with "show capwap client detailrcb" if the BSSIDs are set. The 1st output is for an AP in Flexmode and Client serving, the second one for an AP in sniffer mode:
