Using Routers to Route DSU Management Data
In this example, the DSUs:
H Receive their management data through the Management port connection to
the AUX port of the router.
H Do not route the data among themselves. Routers route management data
for the connected DSUs using the management data path between the
routers.
The illustration shows each DSU with its own subnet. This subnet is independent
of the subnet on the LAN, which is supported by the local router. This enables the
router to distinguish the data destined for the DSU from the data for the LAN.
