8. Run the following command to ensure that the SNMP ports are open before sending traps to the
management station: esxcfg-firewall -e snmpd.
Configuring The SNMP Agent On Systems Running Supported VMware ESXi 4.X And ESXi 5.X
Operating Systems
Server Administrator supports SNMP traps on VMware ESXi 4.X and ESXi 5.X. If a stand-alone license is
only present, SNMP configuration fails on VMware ESXi operating systems. Server Administrator does not
support SNMP Get and Set operations on VMWare ESXi 4.X and ESXi 5.X as the required SNMP support is
unavailable. The VMware vSphere Command- Line Interface (CLI) is used to configure systems running
VMware ESXi 4.X and ESXi 5.X to send SNMP traps to a management station.
NOTE: For more information about using the VMware vSphere CLI, see vmware.com/support.
Configuring 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 configured on the system running Server
Administrator for SNMP traps to be sent to a management station.
To configure 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 configuration takes effect immediately without restarting any services.
Firewall Configuration On Systems Running Supported Red Hat Enterprise
Linux Operating Systems And SUSE Linux Enterprise Server
If you enable firewall 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 firewall 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 firewall, opening an entire external network interface in the
firewall, or opening the SNMP port for at least one external network interface in the firewall. You can
perform this action before or after Server Administrator is started.
