Using SNMP with ESX Server 3i
ESX Server 3i ships with an SNMP management agent different from that which runs in the service console of ESX Server 3. Currently, this SNMP agent supports only SNMP traps, not GETS. This agent is off by default. To use this agent, you must enable the SNMP service, specify at least one community, and configure a trap destination using the remote command-line command vicfg-snmp.
Table 5-10 lists the command options and syntax for the vicfg-snmp command. You must target the vicfg-snmp command directly to the ESX Server 3i host. You cannot use this command with a VirtualCenter Server. For more information on installing and using the remote command-line interface, see the ESX Server 3i Configuration Guide.
