TCP/IP Subagent
State Transitions for Resource Objects
Figure 8-3
illustrates how resource objects move between states. Note that:
Setting a "Connected" object to "Disabled" forces a transition through the
"Disconnected" state. This permits the orderly shutdown of the resource and the
generation of a state change event for the disconnected state.
"Connect Success," "Connect Failure," and "Resource Fault" all relate to actions
and events detected by the subagent. Internally generated transitions produce an
EMS event indicating the state change, as described in
Descriptions
An SNMP general error is returned if the TCP/IP Subagent receives a Set
"enabled" request against a state object that is in the connected state.

Bold text indicates actions and events detected by the TCP/IP Subagent that result
in internally generated transitions.
Set commands are SNMP Set requests against a state object.
Modifying the Value of a Resource Object
To modify the value of a resource object:
1. Set the value of resource object's associated state object to "Disabled."
2. Set the resource object to a new value.
3. Set the value of the resource object's associated state object to "Enabled."
