Configure SNMP Settings for vCenter Server
To use SNMP with vCenter Server, you must configure SNMP settings using the vSphere Client.
Prerequisites
To complete the following task, the vSphere Client must be connected to a vCenter Server. In addition, you
need the DNS name and IP address of the SNMP receiver, the port number of the receiver, and the community
identifier.
Procedure
1 Select Administration > vCenter Server Settings.
2 If the vCenter Server is part of a connected group, in Current vCenter Server, select the appropriate server.
3 Click SNMP in the navigation list.
4 Enter the following information for the Primary Receiver of the SNMP traps.
Option
Receiver URL
Receiver port
Community
5 (Optional) Enable additional receivers in the Enable Receiver 2, Enable Receiver 3, and Enable Receiver
4 options.
6 Click OK.
The vCenter Server system is now ready to send traps to the management system you have specified.
What to do next
Configure your SNMP management software to receive and interpret data from the vCenter Server SNMP
agent. See "Configure SNMP Management Client Software,"
Configure SNMP for ESX/ESXi
ESX/ESXi includes an SNMP agent embedded in hostd that can both send traps and receive polling requests
such as requests. This agent is referred to as the embedded SNMP agent.
GET
Versions of ESX prior to ESX 4.0 included a Net-SNMP-based agent. You can continue to use this Net-SNMP-
based agent in ESX 4.0 with MIBs supplied by your hardware vendor and other third-party management
applications. However, to use the VMware MIB files, you must use the embedded SNMP agent.
By default, the embedded SNMP agent is disabled. To enable it, you must configure it using the vSphere CLI
command
vicfg-snmp
