User couldn't get IP DHCP

Hi everyone,

Im new in aruba controller, i have 13 APs and controller 7005 with OS 8.4.0
2
Currently all AP is on site and controller on DC, connection between site is use MPLSE.
I have 3 SSID with 3 VLAN and DHCP is on Distribution switch on site. So the controller not broadcast the dhcp

The issue is while user connect to ssid, user couldn't get ip although before i convert IAP to CAP all user can connect to ssid and get ip from distribution switch.

Maybe there are wrong on my configuration,
Any idea?

You might have a licensing issue.  That should be resolved first:

Re: User couldn't get IP DHCP

Do you have your SSID forwarding modes configured as "Bridged"?  By default it is tunneled.  Tunneled means that the user traffic would have to go back to the controller.

Re: User couldn't get IP DHCP

I use default "Tunnel"
So i must change to "Bridge" because dhcp is on distribution switch?

Re: User couldn't get IP DHCP

If the traffic is sent out of the access point, the forwarding mode should be bridged.  If the user traffic will be tunneled to the controller and sent out the controller at the DC, the forwarding mode should be tunneled.

Re: User couldn't get IP DHCP

Okay.

 

Forwarding mode should be bridged.  Virtual AP VLAN needs to be 1 if wireless users will be on the same VLAN as the APs.  If the wireless users need to be on a different VLAN, the AP switchport needs to be a trunk and the Virtual AP VLAN needs to be the VLAN you want users to be on.

 

The user role ACLs will be enforced at the AP, but the controller will not have detailed application visibility of user traffic.

 

EDIT:  Control Plane Security needs to be enabled (default), otherwise, forwarding mode bridged will not work.
