Stopping and Disabling the SNMP Daemons

The Sun Management Center agent uses User Datagram Protocol (UDP) port 161 by default to communicate with the Sun Management Center server. The Sun Management Center agent is a complete replacement and enhancement for the SNMP agent snmpdx and the Sun SNMP utility mibissa, which also use port 161 by default.

The SNMP agent snmpdx is the main component of Solstice Enterprise Agent technology. snmpdx and mibissa run as daemon processes and listen for SNMP requests on port 161.

(On Solaris 10) If you use port 161, you are reminded to manually stop and disable the SNMP daemon, SMA.

If port 161 is in use during Sun Management Center setup, you are given the opportunity to specify a different port for the Sun Management Center agent and server, or to continue and use port 161. If you choose to use port 161, you are given the opportunity to stop and disable the SNMP agent daemon.

If you use port 161 and have chosen to manually stop and disable the SNMP daemon, Sun Management Center will not start until you stop all processes that use port 161.

The following procedure applies to any machine on which the Sun Management Center agent has been installed.

To Stop and Disable snmpdx Manually

1. Log in as root.

2. Disable the snmpdx daemon by typing:

   # svcadm disable svc:/application/management/snmpdx

   Note –

   A script whose name begins with an uppercase “S” automatically starts when the system reboots. A script whose name begins with a lowercase “s” is not run automatically.

Troubleshooting

Your system might have other legacy SNMP agents or processes utilizing port 161. If Sun Management Center fails to start even though you have stopped and disabled snmpdx, view the agent.log file /var/opt/SUNWsymon/log/agent.log to see whether there is a port conflict.

To Stop and Disable SMA Manually

1. Log in as root.

2. Stop and disable the SMA daemon by typing:

   # /etc/init.d/init.sma stop
