5.2.1 Testing with TL1Manager:
TL1Manager is a GUI based manager application that can perform all the tasks that can be carried out between the manger and agent.
Follow the steps given below to test the TL1 Manager with the TL1 Agent.
1. To test communication between the manager application and agent, we should log in to the Agent View GUI and through that we can retrieve the list of Agents currently running on the Network Elements.
2.Then we can connect to a required TL1 agent running at a definite port. To establish connection with a TL1 agent, click the connect menu item. This opens the connect dialog where we must enter the device name or IP Address and the port at which it is running. The status bar indicates the status of the connection. Once the TL1Manager establishes connection, we can start sending valid TL1 messages.
3. TL1 messages can be sent to the agent either typing directly in the input message field or can be loaded in the left side frame. TL1 Manager supports two ways of file loading. XML and text file loading. In the case of the XML file loading, we must load both the tcs (TL1 Command Set) as well as the data set file.
4. Now you can select a message from the left side frame or type a new message in the input message field in the right side frame. Click the send button to send a message to the agent. Responses are received in the response tab available in the right side frame. Autonomous messages if any will be received in the autonomous tab.
5.1 TL1 Agent:
The TL1 agent on the managed device serves to provide access to data (managed objects) stored on the managed device. The TL1 manager or management application uses this access to monitor and control the managed device.
The network device is the network component that needs to be managed. The network device contains a management agent that is software for collecting information and making it available to the NMS.
For each network device to be managed there is a need for an agent that makes the management data on the device available. This agent instruments the management data and makes it available to the TL1 Manager. The agent that makes this data available is a TL1 agent.
The agent and the device are two different things, though the agent runs on the device. The device may not always have an agent, in which case the same information is not available to the NMS.
TL1 Manager (NMS or Management application) typically communicate with one or more TL1 agents available in the network to access the information it needs. Data (TL1 messages) are sent and received through RMI with CORBA-IIOP as underlying protocol. These messages allow the TL1 manager to interact with the TL1 agent on the device and thereby manage the device. The extent of management that is possible depends on what the agent makes available. This may be varying from agent to agent.
