Chapter 2 Getting Started With IPM
Configuring the IPM Components
Defining a Collector
Defining a new collector involves selecting a source, a target, an operation, and a collector schedule.
IPM configures collectors on the source device.
There are two modes in which IPM configures a collector:
• Mode 1: Collector is configured on the device without specifying which IP address to be filled in as
source IP address. In this case, SAA fills in the source IP address according to routing table based
on the IP address of the destination. This is the default mode.
• Mode 2: Collector is configured on the device specifying which IP address needs to be filled in as
source IP address. This IP address is the IP address of device known to IPM.
You can set the desired mode by modifying the configuration parameter
IPM_USE_MANAGED_SRC_INTF_ADDR in the ipm.env configuration file. If the value of this
variable is ‘0’, IPM works in mode1. If the value is 1, IPM works in mode 2.
In addition to the above configuration modes, you can also specify the IP address of the interface on
source device to which packets have to be returned from the destination device to source device.
When IP packets are forwarded to the destination device, the SAA fills in the source IP address and the
destination address in the packet. The source address is the IP address of one of the source device
interfaces and it determines the interface to which the packets are returned from the destination.
For information about setting the source interface address as the managed interface address, see
Managed Source Interface Settings.
Defining a collector involves selecting a source router, a target, an operation, and a collector schedule.
To define a new collector:
Step 1 From the IPM Main Window (Figure 2-2), select Edit > Configuration.
The Configuration Window (Figure 2-3) appears.
Step 2 Click Collectors.
The Collector Configuration window (Figure 2-5) appears within the Configuration window.
