Simple DHCP question

I'm trying to set up DHCP in my Aruba IAP-205, and I feel like I'm taking crazy pills. I'm not a networking expert by any means, but this seems difficult.

 

All I want to do, is for one SSID, hand out IPs on the same range the AP itself is on. I've created a Distributed DHCP scope because I think thats what I need to do. It's the only spot that lets me assign a range of IPs. I'm not sure what Clients Per Branch means...What's a branch? Like a separate phyiscal location? I set it to 1. I have a range of 10 IP's, but if I say 10 clients I get an error saying the range is too small.

 

Anyways, I set up the scope, assigned that scope to the Network, but my clients are just get 169 IPs.

 

Any help would be greately appreciated. I am literally trying to do just a very basic networking task, that I've accomplished in hundreds of home routers, but can't for the life of me figure out in this Aruba IAP.

Hi, 

 

Is this a IAP VPN deployment with VPN back to a controller? Or is this just a single IAP deployment? 

Thanks,

Re: Simple DHCP question

I think that on the second page of setting up the ssid you need to select network assign as client ip addressing and vlan default not custom and you are good to go!!!

Re: Simple DHCP question

I've looked at that topic, but when I try to create the DHCP range it won't allow me to set the range, because it's the same subnet as the Aruba's IPs.

 

So what I want to do, is put the Arubas on my network, say 192.168.1.X, and I want them to hand out addresses from 192.168.1.100 - 150. Can I do that? For reasons I don't want to get in to, I can't make my router do this, so I want the Aruba's DHCP server to handle this.

Hi,

You do not need to create DHCP scope on IAP if you want your client to get ip in same range as AP.

In ssid configuration, set the vlan as default.

Re: Simple DHCP question

What I want is for the Aruba to be the DHCP and hand out IPs from a range on that same subnet that I specified. For reasons I won't go in to, my router DHCP is not functional. Can the Aruba be a DHCP server like this?

Re: Simple DHCP question

Actually IAP can do this if the following are observed:


1. There is no other DHCP server on the management subnet.

2. The IAP's own IP is statically assigned.

If this is true then you can create a DHCP scope of Local,L2 type on the same subnet as IAP itself with a custom address range.

Re: Simple DHCP question

Hi Yan,

 

Yes, we can use IAP as DHCP server.

 

Please configure Local DHCP as per your requirement instead of centralized / Distributed.

 

In SSID profile, under Vlan, use Network assigned -> Static -> use the Vlan that was mentioned while configuring DHCP local pool.
