We have VLANs 1 and 21 configured on our network. The MX runs DHCP for VLAN 1 (192.168.1.1/24) and a Windows server runs DHCP for VLAN 21 (221.21.21.1/24). Our switches are downstream port 3 on the MX which is configured to trunk with a native VLAN of 21.   Our end goal is to migrate all clients to the VLAN 1 subnet. We would like to do this incrementally if possible. When configuring a switch port with settings for VLAN 1, the connected client is not able to get an IP address on the 192.168.1.1/24 network even if the IP settings are statically configured on the device. The only method I found for devices to get IP addresses on VLAN 1 would be to update the native VLAN on the MX port to 1, but that migrates the entire switch to VLAN 1 which is not what we want.   Is what we are trying to accomplish possible and what would the best method be for migrating devices connected to individual switch ports to this subnet? ...
