Traffic mirroring (Tool box) T3200m

Can i enable wireless (ssid) to wireless (ssid) traffic mirroring because 

If i enable the SSID 1 (type) > SSID 2 (port) the router reboots and its set to none.

What are SSID 1 & SSID 2? is it the radios 1 = 5g , 2= 2.4g

or is it the SSID# 1 & 2 that we configure in the wireless settings? because i have turned off steering and now have 2 x 2 SSIDs for each radio 5g & 2.4G.
