IP Packet Routing
In Figure 7-18, 24 system units transmit alarm information to an IP routing system unit
(System 25) via the optional paths of separate WAN links. The network administrator assigns
IP addresses for each system on the TCP/IP screen of each system's ICPU card (HOST IP
ADDR). System 20 is connected by any of the optional paths to System 25, which supports
NMS equipment (the communications server) with either a local SLIP connection directly
from the CPU card or any optional path of a T1 or E1 WAN link. In this example, all alarms
received by any of the system units will be forwarded via system 25 to the NMS over a single
WAN link.
Each of the 24 reporting units use NMSs IP address as the RPT1 IP ADDR on the TCP/IP
screen of its CPU card.
The local port is included to be able to transmit the IP packets generated by the routing unit to
the same destination. In most cases, the DEF DEST of all units controlled by this router will
be the same place (either the local port or optional WAN paths to a distant location).
The Routing screen column headings are associated with the incoming WAN link associated
with the IP location of the remote systems. For example, if you expect incoming information
from system 1 on WAN 1-1, you assign the IP address for system 1 IP NET for WAN 1-1.
