Hello, I understand the request now, DHCP config on MS to point APs to two ZD IP addresses.
Marco, Data Type should be "binary", not "string".
Yes, Ruckus APs have an Option 60 in their DHCP request, identifying them as "Ruckus CPE",
and APs look for Option 43 in DHCP offer, using sub-option 03 for ZDs, sub-option 06 to point APs to SZ controllers.
Here are a couple KBAs on the subject, one with MS example scope option shot.https://support.ruckuswireless.com/answers/000004762 https://support.ruckuswireless.com/answers/000003197https://support.ruckuswireless.com/answers/000001255
Another feasible alternative is DNS, you can setup a 'zonedirector.localdomain' hostname (use your local domain)
with the two IP addresses of your ZoneDirectors.
APs will search for last known ZDs or manually configured, L3 discovery of any local ZD, DHCP option 43, or DNS to find their controllers.
(in that order)
If you SSH directly to your APs, you can manually configure their intended ZoneDirector(s), with up to two IPs.
set director ip a.b.c.d a.b.c.e
