ICMP disabled on clients now have HP SIM issues

We have ICMP disabled on some client machines and now HP SIM will not discover these systems. The systems that were already in SIM have a red x on HS.

Does ICMP have to be enabled for HP SIM? I have WEBM enabled, it cant use this for client info?

Re: ICMP disabled on clients now have HP SIM issues

This is set from Options --> Discovery --> Configure Global Protocols Settings. Here is the help text associated with that page:

To set global management 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.

Re: ICMP disabled on clients now have HP SIM issues

Is there a way to leave the global setting at ICMP, but set 1 or 2 clients to an alternate discovery port? I have a handfull of machines in a DMZ I want to monitor with something other than ICMP, but leave the rest of the network on ICMP.
