Native VLAN, Management VLAN, shouldn't be this messy...

Native VLAN, Management VLAN, shouldn't be this messy...

I'm really confused about this. When I set Native VLAN on the upstream port to VLAN 1, the APs get a 192 address (default for that vlan on the meraki dhcp server). If I set the Native VLAN to 20, they get a 172.20 address. All of this is entirely expected and predictable.

 

However, when the VLAN is set to 20, while the AP gets a proper management IP address, the SSIDs stop loading.

 

And if that's not confusing enough, AP-FRONT has a static IP on the DHCP server in VLAN 20 which works fine and can be pinged. AP-OFFICE however is fully dynamic and gets thrown into VLAN 1, while both devices have the same configuration all the way from the SVI to the firewall port.

RIGHT, so I don't know why this is working now, but I changed the MGT VLAN to 1, did a full config update, set it back to 20, did a full config update.

And just for fun, here is some output from the other AP

 

DHCP Tests performed for VLANs 20-20

Passed VLANs:

 20 172.20.0.0/23

Status: complete

Yeah, there's a whole /23 for that VLAN, and barely 40 hosts on it.

Does the DHCP pool for VLAN 20 have an available address for AP-OFFICE? If it does, could you SSH in to AP-OFFICE and run a VLAN probe on the CLI of the AP for VLAN 20? That command will be: int mgt0 dhcp-probe vlan-range 20
