To get SNMP data into and out of MOM, you have to touch the OS, MOM, and the SNMP devices that you want to receive traps from. If you are going to translate alerts into traps, then you need to configure the SNMP service on the management server to send traps to your other SNMP management system.

SNMP management systems and agents are related to each other by an SNMP community name, which is a simple text string and can be anything you want. Be careful though, because text strings are case-sensitive. If you have worked with SNMP, then you will have heard of the private and public SNMP communities. Many SNMP products come preconfigured to work with these two community names . In the example for this chapter, the community name Homelab is used. All SNMP agents need to be told which community they are members of and SNMP management consoles will only manage SNMP agents that are in their community (although they can receive traps from any SNMP agent if so configured). So, your first two steps in configuring SNMP are to pick a community name and a computer to which all traps will be sent. Figure 10-1 shows the top-tier management server, homemomserver3, at 10.0.0.64. With those two decisions out of the way, most of the work in preparing for SNMP is in the OS.
