Wireless Access

Hello Everybody,

I am assigning IP range with mask /24 to my current APs, But we will exceed the amount of IPs because i am gettning more AP. I created a new VLAN to add more APs. is there any requirments to do, to be able to have my APs in two different VLANs? 

Thanks,

Hi Eng Zaz,

To my knowledge, it doesn't matter in which VLAN an AP is, or which IP the AP has. The only important thing is, that the AP needs to know, how to connect to the Controller. How do you solve it today? Is the Controller in the same VLAN as the AP's? Or do they communicate over an L3 connection?

Hi Florian,

The new VLAN is Vlan 34, the old one is Vlan 23, and the Vlan of the controller is Vlan 22.

I can Ping Vlan 23, and Vlan 34 from Vlan 22. so i beleieve the L3 routing is working fine.

but this is the error i get at the AP:

Starting watchdog process...
Getting an IP address...

Looks like you are using L3 for the connection between your AP and the controller. This means you have to tell the AP where the controller is. You should check how you do it in VLAN 23. I would assume it is DHCP based, so the DHCP server is sending option 43 to the AP with the information where to find the controller. you should check this first. If you find something, simply apply the same to VLAN 34. 

Thanks Florian,

I will check my DHCP server and see what is the difference between the two VLans

Thanks,

Easiest way would be to add a dns entry "aruba-master" on your DNS server, point to the master. That way if you add yet another range, you don't have to mess with DHCP.

i added the Controller IP for the option 43, added option 60 and it worked

Thanks everybody
