IP Network Addressing Scenarios
F-6 3160-A2-GB21-80March 1999
Scenario 5
Figure F-5 illustrates multiple COM ports on the same carrier connected to
different NMSs. This might be used in service-provider applications, where some
of the carrier’s circuit cards (and their remotes) are managed by one NMS and
other cards are managed by a different NMS. In this example, each card and
remote is on a separate subnet. Also, note that each LAN Adapter connection is
on a different subnet. The subnet mask is FF.FF.FF.00. The NMS hosts would
only need routes added for the subnets that they are to manage.
