Policy to deny failover to back-up circuits for select VLANs or groups

[Louis]

Hi guys! I am attempting to enforce a policy for two VLANs, wherein one VLAN can failover to a back-up circuit while the other doesn't.

I am sure we can enforce a policy for one VLAN to prefer an uplink in the MX and failover to a back-up uplink either due to link failure or poor performance. However, I am not sure if we can configure a policy in MX that can enforce a VLAN to a desired uplink, but with no failover.

Any help or suggestions will do.

Thank you

Unless it is a USB 4G failover, it can not be done.

Thank you @PhilipDAth. I assume that the USB port is active, i.e., with a cellular modem connected to it.

When you use a USB cellular modem it remains offline until the primary circuit(s) have failed, and then it is bought online.

Here is the section on cellular firewall rules:
