routeros 7.13.5 capsman
complete capsman setup, working and running.
have to use two different radius servers depending on ssid.
found url https://help.mikrotik.com/docs/display/ROS/CAPsMAN and entered in terminal:
/caps-man security add authentication-types=wpa2-eap eap-methods=passthrough encryption=aes-ccm group-encryption=aes-ccm name=radius
/caps-man aaa set called-format=ssid
/radius add address=192.168.30.21 secret=vetimhef service=wireless called-id=g-adm-skuul.de
/radius add address=192.168.31.21 secret=vetimdoc service=wireless called-id=g-skuul.de
the last line entered: "/caps-man configuration set security=radius" simply returns: numbers:
no hint, no chance. tried it with capsman version 7.8: same result.
really disappointed. any help available?

called-id=g-adm-skuul.de
called-id=g-skuul.de

Called-id is normally the SSID. Those here look like invalid SSID names for many vendor implementations. "." and "-" might be not-allowed in the SSID name.

"/caps-man configuration set security=radius" simply returns: numbers"
"set" command uses internal IDs, which you can see with "/caps-man configuration print", you can also use WinBox to apply the profile to the configuration.

Hello and thank you for your answers!
Regarding ssid: indeed, Mikrotik has always allowed minus and dot in the ssid. I have changed the ssids to pure alphanumeric names as a test - the query for "numbers" followed by a number (here 0) still resulted in an abort message.
Your answers have at least helped me to solve the problem of "four ssids with 2 different Radius servers in different networks"
Thank you!
