To enable changes made to the main SMA configuration file, /etc/sma/snmp/snmpd.conf, a signal must be sent to the SMA daemon, snmpd. This signal reads the changes to snmpd.conf and restarts the System Management Agent.
As root, restart the SMA service.
# svcadm restart svc:/application/management/sma:default
This method is the recommended way to restart the System Management Agent.
