By default, Internetwork Monitor places nodes on segment rings based
on network addresses. You can choose to base the node placement on
traffic analysis instead, if you prefer. Additional information on each
placement method is given below.
Figure 35 on page 173 shows the same network data using Address and
Traffic placement.
You cannot change the placement method when the internetwork view is
paused.
For further information on node-to-segment assignments, refer to
page 227.
Address Placement
Address-based placement assigns each node to a segment based on the
node’s network address:
● For IP addresses, the subnet mask for the host running Internetwork
Monitor is applied to node addresses. All nodes with the same address
after applying the mask are assigned to the same segment.
● For non-IP addresses, the network or area number component of the
network address is used. All nodes with the same network/area number
are assigned to the same segment.
This placement method is well suited to networks with a high correlation
between network address and physical topology.
