Configure Device Initiated Connections for Circuits
ION devices can connect to the controller for various services such as MRL service,
statistics, flows, logs, and remote access of device toolkit.

Prisma SD-WAN ION devices initiate multiple
connections to the controller for various services such as Message
Routing Layer (MRL) service, statistics, flows, logs, and remote
access of device toolkit. For services connecting to the controller
using random paths or interfaces, you can exclude certain interfaces
or paths from being used for these services. For example, an expensive
metered LTE circuit is used as a last resort interface to maintain
connectivity to the controller.
In addition, ION devices
generate application reachability probes when an application or
prefix is unreachable for a particular path. However, if a particular
circuit is to be used as a path of last resort only, then the amount
of non end-user traffic going over that specific circuit should
be minimized. You can exclude certain circuits and circuit categories
from being used for device initiated connections by using the Use for controller
connections and Use for application
probes options.
You can prioritize ION device interfaces
use for device initiated connections in the order of first controller
port interface, LAN port, any interface which does not have a label
attached, but has an IP address, and then interfaces with circuit
labels attached. The order of preference is based on the cost of
a circuit. A circuit with a higher cost has a lower preference for
device to controller connections.
- Select .Click Change Circuits for either Internet Circuits or Private WAN Circuits.Click Edit below the circuit name.On the Circuit Information screen, select Yes for Controller Connections, only if using the circuit for connecting to the controller for device related services.Select No, if this circuit is to be excluded from connecting to the controller for device related services such as metered LTE circuits.Select Use Circuit Category Setting for selecting the configuration from the Circuit Category.Select Yes for App Reachability Probes, only if using the circuit for checking the reachability of an application for a given path.Select No, if this circuit is to be excluded from checking the reachability of an application for a given path such as metered LTE circuits. Select Use Circuit Category Setting for selecting the configuration from the Circuit Category.Click Done.

A DEVICESW_INITIATED_CONNECTION_ON_EXCLUDED_PATH alarm is generated when a device initiated controller connection is established using an excluded interface or path. The lack of an available interface or path has forced the connection on an excluded path or interface as a last resort.
