167. Any SNMP request on the VMware MIB branch is rerouted to the vmware-hostd using the proxy feature of the

snmpd daemon.

The VMWware SNMP configuration file can be modified manually on the ESX server or by running the VMware Remote

Command-Line Interface (RCLI) command, vicfg-snmp, from a remote system (Windows or Linux). The RCLI tools can

be downloaded from the VMware website at vmware.com/download/vi/drivers_tools.html.

To configure the SNMP agent:

1. Edit the VMware SNMP configuration file, /etc/vmware/snmp.xml, either manually or run the following vicfg-

snmp commands to modify the SNMP configuration settings. This includes the SNMP listening port, community

string, and the trap target ipaddress/port, and trap community name and then enable the VMware SNMP service.

vicfg-snmp.pl --server <ESX_IP_addr> --username root --password <password>

-c <community name> -p X –t <Destination_IP_Address> @162/ <community

name>

Where represents an unused port. To find an unused port, check the /etc/services file for the port assignment

for defined system services. Also, to make sure that the port selected is not currently being used by any

application or service, run the following command on the ESX server: netstat –a command

NOTE: Multiple IP addresses can be entered using a comma-separated list.

To enable VMWare SNMP service, run the following command:

vicfg-snmp.pl --server <ESX_IP_addr> --username root --password <password>

- E

To view the configuration settings, run the following command:

vicfg-snmp.pl --server <ESX_IP_addr> --username root --password <password>

-s

The following is an example of the configuration file, after modification:

<?xml version="1.0">

<communities> public </communities>

<targets> 143.166.152.248@162/public </targets>

</snmpSettings>

</config>

2. Stop the SNMP service if it is already running on your system by entering the following command: service

snmpd stop

3. Add the following line at the end of the /etc/snmp/snmpd.conf file: proxy -v 1 -c public udp:

127.0.0.1:X .1.3.6.1.4.1.6876

Where X represents the unused port specified above, while configuring SNMP.

4. Configure the trap destination using the following command: <Destination_IP_Address>

<community_name>

The trapsink specification is required to send traps defined in the proprietary MIBs.

5. Restart the mgmt-vmware service with the following command: service mgmt-vmware restart

6. Restart the snmpd service with the following command: service snmpd start

NOTE: If the srvadmin is installed and the services are already started, restart the services as they depend on

the snmpd service.

7. Run the following command so that the snmpd daemon starts on every reboot: chkconfig snmpd on
