Trunking Native Cisco IOS Switch to Meraki MS350 or 210

Im trying to set up a trunk in between a Meraki MS350  a Cisco 3560-12 switch.

 

There are 3 vlans

 

101 for data      10.96.168.0 /22

172 for WIFI      10.96.172.0  /22

201 for voice     10.98.168.0 /22

 

Both The WIFI AP and the phone register correctly with the respective controllers and subnets but the data vlan is blocked

 

 

CST: %SPANTREE-2-RECV_PVID_ERR: Received BPDU with inconsistent peer vlan id 1 on FastEthernet0/12 VLAN101.

CST: %SPANTREE-2-BLOCK_PVID_PEER: Blocking FastEthernet0/12 on VLAN0001. Inconsistent peer vlan. CST: %SPANTREE-2-BLOCK_PVID_LOCAL: Blocking FastEthernet0/12 on VLAN0101. Inconsistent local vlan.

First change to using mst on the 3560.

spanning-tree mode mst

 

Next decide what is the core switch, and change the spanning tree priority on that switch to make sure it is the root.

I wouldn't trunk vlan 1 and use a native vlan at the same time.  Perhaps try:

 

interface FastEthernet0/12
switchport trunk encapsulation dot1q
switchport trunk native vlan 101
switchport trunk allowed vlan 101,172,201
switchport mode trunk

 

I ran into an issue like this with a Nexus. Had to go with:

spanning-tree port type edge

To keep ST in check. Changing root priority did not work for me, but the edge port did.
