This manual has the details about configuring SNMP. Page 258 onwards.

 

Hope this helps

Thanks

RE: port 161/162 not listening on ITA

Usually the first place to look is the SNMP service.  ITA does not directly communicate via 161/162, it just uses the service.  Also, make sure you have open communication with 161/162 UDP.  Setting the right community string and destination address in the service will usually get it done.

RE: port 161/162 not listening on ITA

Here is an extract from the ITA UG for setting up SNMP on ESX servers and sending a trap :

Page 268

Setting Up SNMP on VMware ESX Server 4.0 and Later For Discovery

1 Download the VMware remote command line interface tool (RCLI) from

the VMware website at www.vmware.com. You can download either a

Virtual Appliance, RCLI tools for Linux, or RCLI tools for Windows

operating system.

2 Run the following command on the VMware ESX Server to configure

SNMP from RCLI:

vicfg-snmp --server <ESX_IP_addr> --username root --password <password> -c <community name> -p X -t <ITA_IP_Address>@162/<community name>

Where X represents an unused port.

NOTE: Multiple IT Assistant IP addresses can also be mentioned using a comma-separated list.

3 Stop the SNMP service if it is already running on your system:

Service snmpd stop

4 Add the following line at the end of the /etc/snmp/snmpd.conf:

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.

trapsink <IT Assistant_IP_Address> <community_name>

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

5 Run the following command to enable SNMP for VMware ESX Server:

vicfg-snmp --server <ESX_IP_addr> --username root --password <password> -E

6 Run the following command to view the configuration:

vicfg-snmp --server <ESX_IP_addr> --username root --password <password> -s

7 Restart mgmt-vmware. This takes a few minutes before the service is started.

service mgmt-vmware restart

8 Restart the SNMP service.

Service snmpd start

9 To sustain a system reboot, start the snmpd service.

Chkconfig snmpd on

10 Run the following command to send a test trap to IT Assistant:

vicfg-snmp --server <ESX_IP_addr> --username root --password <password> -T

NOTE: Ensure that the SNMP ports are open before sending traps to the management station by typing

esxcfg-firewall -e snmpd
