Chapter 2 Getting Started With IPM
Configuring the IPM Components
Step 10 In the Source Interface field, enter a valid IP address of the source device interface. This is the IP address
of the source device interface to which the packets are returned from the destination
The Source Interface field is an optional field. If you do not specify an IP address, IPM configures
collector based on the properties specified in the ipm.env file.
Step 11 From the Targets list, select the device to designate as the target. If you already know the name of the
target, start typing the name in the Search field.
The cursor moves to the matching target in the Targets list.
If you select a DNS, DHCP, or HTTP operation, the Targets list is disabled because these operations do
not use targets.
Step 12 From the Operations list, select the operation to use for this collector. If you already know the name of
the operation, start typing the name in the Search field
The cursor moves to the matching operation in the Operations list.
When you install IPM, a group of predefined operations is provided. The predefined operations are
described in Table 2-1.
Table 2-1 Predefined Operations
Operation Description
DefaultDHCP Measures end-to-end latency for acquiring a new DHCP lease.
DefaultDLSw Measures end-to-end latency in a network which uses DLSw to route
SNA traffic over an IP network. Request size is set to 64 and Response
Payload is set to 64.
DefaultDNS Measures end-to-end latency for DNS lookups. DNS Name Server is
set to the IP address of the DNS server configured on the system on
which the IPM server is running. The DNS Lookup Name is set to the
name of the host to look up for the DNS request.
When you create a non-default operation, it is mandatory to specify a
DNS Name Server.
DefaultIpEcho Measures end-to-end latency in an IP network. Protocol is set to IP,
Packet Priority is set to 0 (no priority), and Request Payload is set to
64 bytes.
DefaultIpPathEcho Measures hop-by-hop latency in an IP network. Packet Priority is set
to 0 (no priority), Request Payload is set to 64 bytes, Maximum Paths
is set to 5, Maximum Hops is set to 15, and sample interval is set to
180 seconds.
DefaultNNTP Measures the time to perform a TCP connect operation directed at the
selected target on the standard Network News Transport Protocol
(NNTP) port 119. Packet Priority is set to 0 (no priority) and Target
Port is set to 119.
DefaultPOP3 Measures the time to perform a TCP connect operation directed at the
selected target on the standard Post Office Protocol v.3 (POP3) port
110. Packet Priority is set to 0 (no priority) and Target Port is set to
110.
