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!

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.
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
