Assigning DHCP to VLAN

Assigning DHCP to VLAN

My DHCP is handled by the MS350. Under Switching - Configure - Routing & DHCP I have created multiple interfaces.

 

For example:

I want clients connecting to the "WiFi" to get IP addresses from the DHCP server set up on VLAN 80. Currently they are only getting IP addresses from VLAN 1. 

 

Under the SSID settings, I tag VLAN 80.

All of my switches are connected using SFPs. Those ports are configured with like this:

VLAN 99 is my management VLAN, all switches are configured this way. What do else do I need to configure before pulling the trigger on the SSID setting?

Kind of a big deal

The ports that APs are connected to are Trunked with the native vlan of 99 as you've shown above? Your SSID settings appear correct, so I'd be verifying the APs are trunked on a native vlan other than 80 and that 80 is an allowed VLAN

Those settings are for the SFP ports. My switch ports are set up as follows. This is a port with attached AP.

This looks like it should work.  If you statically IP something on VLAN 80 and connect to the SSID in question does it work?  If not does it work (DHCP or static) if you put a wired device on access vlan 80? If you don't see something obvious (bad trunk) you can do this starting with your core switch and moving outwards to try to identify where the problem is. 

You also may want to call support, they can probably help pretty quickly identifying where the problem is.

We are currently in session but will begin testing during the lunch break. I will report back with my findings. Thanks for the input.

So, I have I am testing in my office. I have 7 devices connected to the AP. 4 devices are connected to the "wifi" ssid. They are pulling an IP from the associated DHCP. Perfect. But..

 

My laptop is pulling from a different DHCP server, one that is for the Access Control VLAN. I have verified no reservations for that MAC. I have also checked all uplink ports, and they are all configured the same. (noted in the previous post)

 

Here is a list of clients connected to the AP in my office.

Is it possible you have a misconfiguration somewhere somewhere with a port in the access control vlan connected to a port in the wifi vlan? Maybe a dumb switch someone has installed so it's not obvious?

I can't think of any other scenario that could happen within your setup, outside of a bug on the MS350 that support would have to identify.

Currently tearing through closets and looking for just that. Thanks again. I will update when I know more .

The switch port where the access point is located must be configured in trunk mode.
VLAN in the SSID as per the image you sent.

I made that changes I last posted. Currently all devices connecting to that AP are pulling from the proper DHCP server. I am going to test further and report back. Thanks to everyone for the input.
