Configuring protocol settings

Select OptionsProtocol SettingsGlobal Protocol Settings. The Global Protocol Settings page appears.

In the Default ping settings section, select Use the Internet Control Message Protocol (ICMP) for system reachability (ping) check or Use the TCP protocol for system reachability (ping) check port number 80. The Use the ICMP protocol for system reachability (ping) check option is the default and recommended setting.

Select Use the TCP protocol for system reachable (ping) check. port number 80 if your company has disabled ICMP on the corporate network or the corporate policy mandates system firewall software to filter out ICMP requests. For example, Windows XP has this feature built in and can result in systems not being automatically discovered. This option enables you to run HP SIM and ping all available systems.

Note: This option only applies to IP-based systems and is available for global, system-wide settings that are used when managing all systems in HP SIM. It is used by automatic discovery, hardware status polling, the ping tool, and any other tool that must verify system availability. This option is not available on a single-system basis.

Note: If you select Use the TCP protocol for system reachable (ping) check. port number 80, even though HP SIM attempts a connection request to the current system, that system does not need any additional software running on it for this option to work. For example, HP does not require that a web server be running on port 80. Some networking systems might not respond to the TCP request, which is typically seen in low-end networking equipment. Manual additions can be made if it is necessary. However, this system displays as Critical if hardware status polling is run.

Note: If you need to use a port other than port 80, you can change the NodeReachableTcpPort property in the globalsettings.props file located in C:\Program Files\HP\Systems Insight Manager\config\globalsettings.props for Windows and in /etc/opt/mx/config/globalsettings.props for HP-UX and Linux.

Set the Default timeout and the Default retries. If some systems are managed over a WAN or satellite link, use a larger time-out (for example, five seconds) with at least one retry. For a LAN, a shorter time out can be used. This setting can be configured on a single-system basis.

In the Default WBEM settings section, select Enable WBEM to allow Web-Based Enterprise Management (WBEM) requests to be sent. Enabled is the default setting. Enter as many default user names and passwords as needed. If your network includes storage systems, enter the user name and password of each SMI CIMOM in this section. The identification process attempts each of these user name and password pairs until a successful response is obtained. Future WBEM requests to that system use the user name and password that succeeded. For Windows-based systems, the user name should include the domain name, for example, domainname\username.

Note: If you have WBEM systems and no user name and password pairs are entered, the systems will not be discovered.

Note: Order the name and password pairs such that root and administrator passwords are listed first and user and guest passwords are listed second. This order minimizes the search time.

Note: HP recommends limiting the WBEM user name and password pairs to 10 to reduce the overall discovery run time. To add more than 10 WBEM user name and password pairs, run mxnodesecurity -a -p wbem -c username:password for each additional set. You can also create an XML file that defines your system authorizations prior to running discovery.

Note: OpenWBEM is not supported.

In the Default HTTP settings section, select Enable HTTP and HTTPS if it is necessary to allow web-based agents and other HTTP port scans to be identified. HP recommends leaving this option enabled for proper management and discovery of systems.

In the Default SNMP settings section, select Enable SNMP, which is the system default, and set the Default time out and Default retries. If some systems are managed over a WAN or satellite link, use a larger time-out (for example, five seconds) with at least one retry. For a LAN, a shorter time out can be used. These settings can also be configured on a single-system basis.

(Optional) Enter the Default write community string. This value is case-sensitive. Only a few tools need this option set. Community strings are case-sensitive.

Enter the Read community string. This value is case-sensitive. Enter as many as needed. The identification process attempts communication to the system, using each of these communities in succession until a successful response is obtained. Future SNMP requests then use the community string that provided a successful response.

Note: If you have SNMP systems and no read community string that match the systems are entered, the systems will not be discovered.

(Optional) In the Default DMI settings section, select Enable DMI, to enable Desktop Management Interface (DMI) identification to run on systems. DMI is used to manage some older desktops, HP-UX 11.0 servers, and some third-party servers. If you do not need to manage these kinds of systems, DMI can be disabled to improve discovery performance.

Note: DMI is not currently supported on Linux systems and is not shown in the user interface.

Note: If DMI is disabled and some systems no longer have a correct system type or product name, re-enable DMI.
