Managing Exchanges
Chapter 4 Discovering and Managing Objects 101
Managing Exchanges
An exchange is the data transfer between a source and a destination, which can be
seen by a Cisco router with NetFlow. RMON2 probes and NetFlow technology can
retrieve exchange information. In the
Network tree, exchanges appear below an
exchange root that is below RMON2 probes and Cisco routers that have NetFlow.
Creating a New Exchange
In creating a new exchange, you must define the source and the destination of an
exchange. For RMON2 probes, you can create exchanges between one IP address and
another. For Cisco routers with NetFlow, you can create exchanges between an IP
address, a range of IP addresses, a subnet, or a group.
■ IP address, or a range of addresses, or a subnet
A range of IP addresses has a beginning IP address and an ending IP address
separated by a minus sign, such as 123.111.222.120–123.111.222.129. A subnet is
made up of a network address and a mask, separated by a slash, such as
122.111.222.0/255.255.255.0
■ group
Groups are supersets made of combinations of IP addresses, ranges of addresses,
or subnets (referred to as subareas). In a combination, a + sign precedes an
included subarea and a - sign precedes an excluded subarea. In a combination that
defines a group, if some a network object is part of more than one area, the last
inclusion or exclusion instruction overwrites the preceding ones. For example, if a
device belongs to subarea1 and subarea3, this device is part of the
-subarea1+subarea2+subarea3 group (first excluded with subarea1, then included
with subarea3), but it is not part of the +subarea1+subarea2-subarea3 group (first
included with subarea1, then excluded with subarea3).
NOTE
A group is identified with a label and is global to PATROL DashBoard instead of
being dedicated to a Cisco router. Any change in a group or in a subarea of a group
applies everywhere in PATROL DashBoard.
