Automatic WAN Link
Discovery
3Com Network Director provides basic automated support for
discovering and displaying the WAN interfaces on your routers. This
support is part of the normal Network Discovery process, and requires no
additional configuration beyond that normally needed to discover a
device.
When 3Com Network Director discovers a router in your network it
determines which, if any, of the active interfaces on the router are WAN
interfaces. The supported interface types are listed in “
Supported WAN
Interface Types” on page 748. 3Com Network Director then creates links
from each of these interfaces to a single Default WAN cloud in the map,
as shown below:
Figure 367 Default WAN cloud
3Com Network Director does not perform any topology analysis on the
WAN segments of your network. If you want to display the correct WAN
topology in your map then you can do this by manually modifying the
topology. See “
Manual Layout of WAN Topology” on page 688 for
details of how to achieve this.
