For agents using a LAN port, the IP addressing is used to determine through which LAN port communication should take place. What may be required is the setup of external routes to the various management communication networks that will be accessed using Ethernet, MPLS-TP (PVC, PWAC), Qx, ECC or DCC interfaces. This is best done in the FOXMAN‑UN dialog that is used to create the agents themselves as this ensures that the routes will be re-established upon re-boot. It will also ensure that the routes are removed if the agent is stopped.
