To configuring SNMPv3 after enable snmp, set user, authentication and/or encryption for the switches: ::
chdef frame01sw1 snmpauth=sha snmppassword=xcatpassw0rd snmpprivacy=DES snmpusername=xcatadmin
then execute the ``configonie`` command to add the snmp user for the switch: ::
/opt/xcat/share/xcat/scripts/configonie --switches frame01sw1 --snmp
To verify the SNMPv3 configuration, run ``xcatprobe switch_macmap`` command, will show following results: ::
