The system detects hosts on which JP1/Software Distribution is not installed by comparing the MAC addresses of the hosts registered in the managing server with the MAC addresses of the hosts found in the network.

This subsection describes MAC addresses and JP1/Software Distribution versions that can be detected.

Two types of MAC addresses are registered in the managing server:

• MAC addresses registered as system configuration information
• MAC addresses obtained by the Get system information from client job

If the MAC address of a found host does not match either of these MAC addresses, the system assumes that JP1/Software Distribution is not installed on that host and treats it as a host on which JP1/Software Distribution is not installed.

If the system cannot obtain a MAC address, it assumes that JP1/Software Distribution is not installed on that host. Therefore, to use the results of detecting hosts on which JP1/Software Distribution is not installed, your system must consist of JP1/Software Distribution versions that support MAC addresses. The following table lists the JP1/Software Distribution versions that are capable of obtaining MAC addresses.

Table 9-3 JP1/Software Distribution versions capable of obtaining MAC addresses

JP1/Software Distribution		Version
Windows version	Manager (relay manager)	05-12 or later#1
	SubManager	03-10 or later#1
	Client	03-10 or later#1
UNIX version		06-71 or later#2

#1

If inventory is not managed, MAC addresses can be obtained only from JP1/Software Distribution version 06-00 or later.

In an environment in which at least one host uses multiple network adapters, MAC addresses can be obtained only from JP1/Software Distribution version 06-01 or later.

#2

If inventory is not managed, MAC addresses can be obtained only from JP1/Software

Distribution version 08-10 or later. You must specify the settings for MAC addresses to be acquired in the system configuration information.
