Select Set read community string to specify a community string. By default, the first HP SIM community

string that is not public appears. If no community string exists in HP SIM, you must enter one.

NOTE: If you configure only HP-UX systems with default SNMP installations, you do not need to set this

option. HP-UX enables read by default (get-community-name is set to public by default on HP-UX systems).

NOTE: If you select this option, the Read Only community string is added to the target systems. If the target

system is SuSE Linux or Microsoft Windows 2003, the managed systems do not always enable SNMP

communication between themselves and a remote host. This setting is modified to enable the instance of the

HP SIM system to communicate using SNMP with these target systems.

NOTE: You can enter a community string up to 255 characters.

NOTE: Repairing the SNMP settings adds a Read Write community string to the target system only if one

does not currently exist. This community string is unique for each system, is composed of over 30 characters

to include letters and numbers, and is visible only to the user with administrator privileges for that system.

This Read Write community string is required by the Web Agent to perform certain threshold setting

capabilities. This community string is used locally only on the target system and is not used by HP SIM over

the network. Linux and HP-UX systems do not require a Read Write community string. The Read Write

community string is added on Windows systems only.

Select Send a sample SNMP trap to this instance of the HP SIM to test that events appear in HP SIM

event lists to verify that SNMP events appear in the HP SIM events list.

To successfully send a test trap, you must configure target systems to send a trap to this instance.

NOTE: You can send a test trap only from a managed system with an HP Insight Management Agent

installed.
