Trunking Between 3750-X Switches - Meraki APs

[wasbitony]

Hi,

I'm currently trying to configure Meraki APs on a trunked, layer 2 3750-X switch. I am able to configure my trunk link properly as follows on both switches as follows:

interface GigabitEthernet1/0/1
switchport trunk encapsulation dot1q
switchport trunk native vlan 110
switchport trunk allowed vlan 12,101,110
switchport mode trunk

VLAN 101 is our data traffic, and VLAN 12 is dedicated to our WiFi traffic. On the downstream switch, I am unable to get any sort of connection to the Meraki AP when configured as follows. The idea is that the Meraki AP will be using VLAN 101 to get an IP address for itself, then distribute IPs to mobile devices based on VLAN 12: 

switchport trunk encapsulation dot1q
switchport trunk native vlan 101
switchport trunk allowed vlan 12,101
switchport mode trunk
switchport nonegotiate
spanning-tree portfast trunk

Now I'm aware that Layer 2 devices cannot configure IP addressing, but is there a way I can get these devices to use the same IPs as the upstream switch? This is being used for an athletic field project, so I'd rather have IPs be consistent all over, rather than creating all new VLANs/IP pools. Having an IP for one area of the field and then having to move to another part could cause IP addressing problems that I'd like to avoid. 

Thank you! Apologies if what I'm asking for is too simple lol.

Trunk Between 3750-X Switches  - both the switches 3750X and one of the switch you have Meraki AP connected is this correct.

When you trunk between 2 devices always suggest to match the config both the sides including native VLAN best practice to get optimal outcome.

make sure both the switches have same VLAN created and participated in STP.

match the config both the side same as below :

switchport trunk native vlan 110
switchport trunk allowed vlan 12,101,110

The configuration is matched on both sides. I can get the AP to receive an IP on the downstream, trunked switch. However, it cannot further tag traffic into the appropriate VLAN. 

For example, I have 10.3.61.1 255.255.255.0 in VLAN 101. And VLAN 12 is our WiFi VLAN at 10.3.72.1 255.255.255.0. The AP receives a 10.3.61.x address, but if my phone wanted to connect to the AP, it cannot receive a 10.3.72.x address. I've configured the port that the AP resides on as a trunk port as follows:

interface GigabitEthernet1/0/4
switchport trunk encapsulation dot1q
switchport trunk native vlan 101
switchport trunk allowed vlan 12,101
switchport mode trunk
switchport nonegotiate
spanning-tree portfast trunk

Thanks!

Do you mean configure the APs within the same MGT vlan as the switches not the exact same addressing?
