Hi Sam,

Please ask this question to the SmartCell Gateway and virtual SmartCell Gateway forum. The Ruckus Cloud forum only covers the Ruckus Cloud WiFi products. Since you have a controller the other forum should be able to assist you.

The article Mike Brado sent you should answer your questions also. If you still need assistance don't hesitate to open a support case here... https://support.ruckuswireless.com/contact-us

Michael, I get nowhere when click the link.  Can you email the article to me please?  Or what is the title or the articles, maybe I try to google from internet?  Thanks.

Hi Sam,

In Smartzone 5.0, Depending on where you are attempting to start capture mode, you may need to provide the MAC address of the AP and DataPlane (DP).  If you highlight the AP in question from the Access Point list, hit the "More" drop down and begin the .pcap from there, you should be presented with options for 2.4GHz/5GHz/Wired interface, and whether to save as a local file or stream to a Wireshark endpoint. 

If you are attempting to capture from a radio interface you have turned off (if you've disabled 2.4GHz in your environment for example) it may throw the error you are describing.
