Starting and Stopping the IMS AAA Server
This section describes how to start and stop the IMS AAA Server.
During the server installation procedure, if you answered "Yes" when asked:
Do you want to configure a3s to be automatically launched during boot time and stopped during shutdown time [y,n]: y
the server will automatically re-start each time the host machine is booted. Two sets of scripts are created in /etc/rc2.d directory as follows:IMS AAA Server Scripts:
-starts the server
-stops the serverSNMP Agent Scripts:
-starts the SNMP agent
-stops the SNMP agent
However, if you answered "No" to this question, you will need to manually start the server and (optionally) the SNMP agent, whenever the host machine is booted.
Manually Starting and Stopping the Server or SNMP Agent
When you execute the stop command, it allows the server sub-systems to complete outstanding work, release resources, and then stops the server and/or the SNMP agent gracefully.
Manually Starting and Stopping the IMS AAA Server
To manually start the server:
# ./S90a3s start
You should see the following response:Process ID of daemon is 10659root@myserver:/opt/AAA/a3s #starting...system started.
To manually stop the server:
# ./S90a3s stop
Manually Starting and Stopping the SNMP Agent
To start the SNMP agent:
# ./S89snmpd start
No response is displayed. To verify the SNMP agent has started, enter the following command:
# ps -ef|grep a3s
You should see the following response:/opt/AAA/a3s/snmp/bin/snmpd -c /opt/AAA/a3s/snmp/conf/snmpd.conf 161
To stop the SNMP agent:
# ./S89snmpd stop
When you manually start the SNMP agent and the server, we recommend you start the SNMP agent first, and then start the server. This ensures the IMS AAA Server Startup and Diameter Peer Connection Up alerts are captured by SNMP the agent. To manually stop the server and the SNMP agent, stop the server first, and then stop the SNMP agent. This ensures the IMS AAA Server Shutdown and Diameter Peer Connection Down alerts are guaranteed are captured by the SNMP agent. For more information, see Configuring the SNMP Alerts.
The first time you start the IMS AAA Server, SNMP alerts are not generated until you configure the Server Management > Alerts and Apply the changes to the IMS AAA Server. See Configuring the SNMP Alerts.
