Conguring the SNMP agent on systems running supported VMware ESXi 6.X operating systems
Server Administrator supports SNMP traps on VMware ESXi 6.X. If a stand-alone license is only present, SNMP conguration fails
on VMware ESXi operating systems. Server Administrator does not support SNMP Get and Set operations on VMware ESXi 6.X as
the required SNMP support is unavailable. The VMware vSphere Command-Line Interface (CLI) is used to congure systems
running VMware ESXi 6.X to send SNMP traps to a management station.
NOTE: For more information about using the VMware vSphere CLI, see vmware.com/support.
Conguring Your System To Send Traps To A Management Station
Server Administrator generates SNMP traps in response to changes in the status of sensors and other monitored parameters. One
or more trap destinations must be congured on the system running Server Administrator for SNMP traps to be sent to a
management station.
To congure your ESXi system running Server Administrator to send traps to a management station:
1. Install the VMware vSphere CLI.
2. Open a command prompt on the system where the VMware vSphere CLI is installed.
3. Change to the directory where the VMware vSphere CLI is installed. The default location on Linux is /usr/bin. The default
location on Windows is
C:\Program Files\VMware\VMware vSphere CLI\bin.
4. Run the following command: vicfg-snmp.pl --server <server> --username <username> --password
<password> -c <community> -t <hostname> @162/<community>
where <server> is the hostname or IP address of the ESXi system, <username> is a user on the ESXi system,
<community> is the SNMP community name and <hostname> is the hostname or IP address of the management station.
NOTE: The extension .pl is not required on Linux.
NOTE: If you do not specify a user name and password, you are prompted.
The SNMP trap conguration takes eect immediately without restarting any services.
Firewall Conguration On Systems Running Supported Red Hat Enterprise Linux Operating
Systems And SUSE Linux Enterprise Server
If you enable rewall security while installing Red Hat Enterprise Linux/SUSE Linux, the SNMP port on all external network interfaces
is closed by default. To enable SNMP management applications such as IT Assistant to discover and retrieve information from Server
Administrator, the SNMP port on at least one external network interface must be open. If Server Administrator detects that the
SNMP port is not open in the rewall for any external network interface, Server Administrator displays a warning message and logs a
message to the system log.
You can open the SNMP port by disabling the rewall, opening an entire external network interface in the rewall, or opening the
SNMP port for at least one external network interface in the rewall. You can perform this action before or after Server
Administrator is started.
To open the SNMP port on Red Hat Enterprise Linux using one of the previously described methods:
1. At the Red Hat Enterprise Linux command prompt, type setup and press <Enter> to start the Text Mode Setup Utility.
NOTE: This command is available only if you have performed a default installation of the operating system.
The Choose a Tool menu appears.
2. Select Firewall Conguration using the down arrow and press <Enter>.
The Firewall Conguration screen appears.
3. Press <Tab> to select Security Level and then press the spacebar to select the security level you want to set. The selected
Security Level is indicated by an asterisk.
NOTE: For more information about the rewall security levels, press <F1>. The default SNMP port number is 161. If
you are using the X Window System graphical user interface, pressing <F1> may not provide information about
rewall security levels on newer versions of Red Hat Enterprise Linux.
a. To disable the rewall, select No rewall or Disabled and go to Step7.
