DHCP Option 43 for Ruckus AP

[ERIK S]

Hello everyone,

Just trying to get some feedback on this configuration that I am trying to implement and trying to see if any of you have encountered this issue.

I have a Cisco 2960X that I will be using as a DHCP server at a remote site.

This switch will have several Ruckus 500 APs hanging off of it.

I have configured the ports as follows:

Switchport trunk encap dot1q

Switchport mode trunk

Switchport native Vlan 2

I have configured the DHCP pool as follows:

ip dhcp pool WLAN
   network 10.x.x.0 255.255.254.0
   dns-server 8.8.8.8
   default-router 10.x.x.1
   option 43 hex 030831302e312e312e31
   lease infinite

The issue that I run into is that the AP is receiving the IP but it not receiving the Option 43 information.

I have also tried using the following command: Option 43 ascii "10.x.x.1"

I haven't had much luck searching on Ruckus' forum.

TYAFYS!

10.x.x.1 isnt the controller AP I just included it for the sake of demonstration purposes.

That's the wrong syntax.  What is the IP address/addresses of the controller?

Hello

example:
172.16.1.254
AC  10 1 FE

hex f10

4 = single controller
8= two controllers
etc...

option 43 hex f104AC101FE  = 172.16.1.254

option 43 hex f108AC101FEAC111FE  = 172.16.1.254, 172.17.1.254

etc..

I apologize for the confusion. This is a Ruckus controller that the APs are connecting to. I am aware that if it was a Cisco Controller the option would start with a "F". The engineers are Ruckus were kind enough and forwarded me a link for a decimal to hex calculator for Cisco Controllers as well as Ruckus Wireless ZD and SCG.

https://shimi.net/services/opt43/index.php

The IP of the controller is 192.168.40.11

This is the output I get from the calculator.

option 43 static prefix for vendor Ruckus Wireless (ZD): 03 (hex)
IP count: 1
Concatenated IP string is: 192.168.40.11 (length: 13/0x0d chars)
Which translates to... 3139322e3136382e34302e3131 (hex)

Resulting IOS command would therefore be:

option 43 hex 030d3139322e3136382e34302e3131

Thanks
