ZoneDirector DHCP Discovery

Question

Hello,

to discover my ZoneDirector's i decided to use my DHCP to provision my APs.

I tried to unterstand the ZoneDirector User Guide (Version 9.8) and configured following Settings:

- Define Vendor Classes "RuckusWirelessAP" and wrote "Ruckus CPE" in the ASCII field

- Open "Set Predefined Options...", choose my prevously created Class and add a sub-option.

Here ist my question:

What kind of "Data type" should i use?

I cant find any Information in the User Guide and i tried several Types without Success.

Please help.

Thanks!

Best Regards

Marco

I'd like to elaborate that this configuration is on Windows Servers in order to have option 43 provided to only Ruckus clients which include "Ruckus CPE" option 60 in DHCP request.

I too had this issue. To make this work I defined a vendor class ID with the ASCII characters "Ruckus CPE". I then created a predefined option in the class named option 43 with code 006. Then I created the scope option. Using the advanced tab in scope options I chose the custom Ruckus CPE vendor class and predefined option I had created and entered the two controller IPs with a comma between them in the ASCII field.

If your using ZDs use code 003 when creating the predefined option in the vendor class.

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.

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
   reboot
