To change the default SNMP community name used for retrieving management information from a system running Server Administrator:

1. Open the SNMP agent configuration file, /etc/snmp/snmpd.conf.

2. Find the line that reads: rocommunity public 127.0.0.1.

3. Edit this line by replacing public with the new SNMP community name. When edited, the new line should read: rocommunity

community_name 127.0.0.1.

To enable SNMP configuration changes, restart the SNMP agent by typing: systemctl restart snmpd .

Configuring the SNMP agent on systems running supported Ubuntu

server

Server Administrator uses the SNMP services provided by the net-snmp agent. You can configure the SNMP agent to enable SNMP

access from remote hosts, change the community name, and send traps to a management station. To configure your SNMP agent for

proper interaction with management applications such as OpenManage Essentials, perform the procedures described in the following

sections.

NOTE:

For additional details on SNMP configuration, see the operating system documentation.

Sever Administrator SNMP Install Actions

Server Administrator SNMP communicates with the SNMP agent using the SMUX protocol. When Server Administrator SNMP connects

to the SNMP agent, it sends an object identifier to the SNMP agent to identify itself as a SMUX peer. To support SMUX the object

identifier must be configured with the SNMP agent. In order to Server Administrator work with SMUX protocol you need to enable by

following the below steps to the SNMP agent configuration file.

• Open the SNMP agent configuration file./etc/default/snmpd.

• The default option available in the configuration file is: SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -g snmp -I -

smux,mteTrigger,mteTriggerConf -p /run/snmpd.pid'

• With the above default configuration the SMUX module is disabled.

• To support snmpd to support SMUX change the configuration as : SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -g snmp -

p /run/snmpd.pid'

Add in the SNMP agent configuration file ./etc/snmp/snmpd.conf

smuxpeer .1.3.6.1.4.1.674.10892.1

• To enable the SNMP configuration changes, restart SNMP agent by using: systemctl restart snmpd.

Changing The SNMP Community Name

Configuring the SNMP community name determines which management stations are able to manage your system through SNMP. The

SNMP community name used by management applications must match the SNMP community name configured on the system running

Server Administrator, so the management applications can retrieve the management information from Server Administrator.

To change the default SNMP community name used for retrieving management information from a system running Server Administrator:

1. Open the SNMP agent configuration file, /etc/snmp/snmpd.conf.

2. Find the line that reads: rocommunity public 127.0.0.1.

3. Edit this line by replacing public with the new SNMP community name. When edited, the new line should read: rocommunity

community_name 127.0.0.1.

4. To enable SNMP configuration changes, restart the SNMP agent by typing: systemctl restart snmpd .

Configuring 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 configuration 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 configure 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.
