Configuring protocol settings

Configuring the protocol settings defines how HP SIM communicates with the managed systems.

To configure the protocol settings:

Select OptionsProtocol SettingsGlobal Protocol Settings. The Global Protocol Settings page appears.
In the Ping settings section, choose from the following options:
- (Recommended) Use the ICMP protocol for system reachability (ping) check. This setting is the default.
- Use the TCP protocol for system reachability (ping) check. TCP port number. Select this setting if your company has disabled ICMP on the corporate network or if the corporate policy mandates system firewall software to filter ICMP requests. Enter the port number.
  Windows XP has this feature built in and can prevent systems from being automatically discovered. This option enables you to run HP SIM and ping all available systems.
  This option applies to only 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.
  When HP SIM attempts a connection request to a 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. You can make manual additions, if necessary. However, this system displays as Critical if hardware status polling is run.
Set the Default timeout and the Default retries. If some systems are managed over a WAN or satellite link, use a longer time-out (for example, five seconds) with at least one retry. For a LAN, you can use a shorter time-out. You can configure this setting on a single-system basis.
In the WBEM settings section, verify that Enable WBEM (the default) is selected to allow WBEM requests to be sent.
To access the Global Credentials page, select Go to the Global Credentials page to set global WBEM credentials.
OpenWBEM is not supported.
In the HTTP settings section, select Enable HTTP and HTTPS if you need 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 SNMP settings section, verify that Enable SNMP (the default) is selected and specify values for Default time out and Default retries. For systems 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. You can configure these settings on a single-system basis.
To access the Global Credentials page, select Go to the Global Credentials page to set global SNMP community strings.
In the Read community string field, enter up to 10 read community strings. This value is case-sensitive. The identification process attempts communication with a 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.
If you have SNMP systems and no read community string that match the systems entered into HP SIM through Global Protocol Settings or System Settings, the systems are not discovered.
In the WS-MAN settings section, verify that WS-MAN is enabled and enter a Default identity timeout.
In the SSH settings section, select Enable SSH to enable SSH identification to run on managed systems.
(Optional) In the DMI settings section, select Enable DMI, to enable DMI identification to run on managed 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, you can disable DMI to improve discovery performance. DMI is not enabled by default.
DMI is not currently supported on Linux systems and does not appear in the user interface.
If DMI is disabled and some systems no longer have a correct system type or product name, re-enable DMI.
Click OK to accept the settings.
