Launching the SNMP Adaptor

We launch the SNMP adaptor in the same way that we launch the HTML adaptor. First we create a meaningful object name for its MBean, then we instantiate the class with a constructor allowing us to specify a non-default port, we register the MBean with the MBean server, and we start the adaptor to make it active.

By default, the SNMP protocol adaptor uses the standard SNMP port 161. Since other applications may be using this port on a machine, our simple agent uses port 8085. When we connect to this agent our SNMP manager will need to specify this non-standard port number.

On certain platforms, applications also require super-user privileges to assign the default SNMP port 161. If your SNMP adaptor uses this port, its agent application will have to be launched with super-user privileges.
