OK, I am having an issue figuring this out
I have a MX connected to a MS350 switch, and since the trunk port was getting errors, I made the connection an access port instead of a trunk.
So the MX has a VLAN 101 interface 192.168.101.2 /24 connected to 1 on the switch, which is in VLAN 101 and configured with a static address 192.168.101.10 /24.
All that works fine, as the switch talks through the MX to the cloud, etc.
Problem is, I now want to create another subnet/vlan/SVI on the switch for my wireless network, and route to the Internet. Is this even possible with the current setup? What is the workaround?
