Log in as root on the Sun Management Center server-layer machine.
Locate a range of unused ports.
Type /opt/SUNWsymon/sbin/es-config -P 6000:6150.
The difference between the starting port number and the ending port number must be at least 100.
es-config stops all Sun Management Center processes. The port numbers currently assigned to the Sun Management Center components are then displayed. You are then informed that /var/opt/SUNWsymon/cfg/domain-config.x has been updated for the new configuration.
The Sun Management Center components are started.
