TrafficDirector provides powerful monitoring for PVCs. Each PVC is represented by an associated DLCI, and for each DLCI the probe discovers on the network, the agent creates a DLCI interface. Using TrafficDirector, you can monitor each DLCI interface just as you would any other agent. For example, you can install domains and alarms, and enable logging for in-depth monitoring of each DLCI.
A Frame Relay agent is a WAN interface set up to monitor a Frame Relay segment. When you add a Frame Relay agent to TrafficDirector using Configuration Manager, you also see all the DLCIs that the probe discovered on the selected network segment.
Configuration Manager lets you monitor DLCIs as individual agents using protocol domains. All protocol domains that you install on the physical Frame Relay interface using a shared properties file are automatically propagated to all DLCIs on that interface. You can also configure traps and logging for individual DLCIs using the custom properties file for the selected Frame Relay interface.
For example, if you want to monitor IP host and conversation statistics, you enable host and conversation statistics for the IP domain on the physical Frame Relay interface that you added to TrafficDirector, and the agent will configure all DLCIs on the selected interface to track IP hosts and conversations. The agent will also enable IP hosts and conversations for any new DLCIs it discovers on the selected network segment. Similarly, if you disable IP hosts and conversations on the physical Frame Relay interface, the agent disables IP hosts and conversations for all DLCIs discovered on that interface. If you do not want to generate reports for all PVCs on a selected interface, you can install a custom properties file on the physical Frame Relay interface to define logging only for selected DLCIs.
You add a Frame Relay Agent as you would any common agent. To add a Frame Relay agent, take the following steps:
Step 1 Launch Configuration Manager, if you have not already done so. See Chapter 4, "Configuration Manager."
Step 2 Select the FrameRelay radio button.
Step 3 Click Add.
The Add Frame Relay Agent window opens (Figure 7-1).
Step 4 Enter the information in the appropriate fields.
See Chapter 5, "Agents" for a description of each field.
Step 5 Do one of the following:
Step 6 Click Test to confirm that the new agent can be reached. See Chapter 16, "Testing the Operational Status of an Agent."
When you have added a Frame Relay agent to TrafficDirector, you can edit it at any time and change any of the parameters you specified when you added the agent. For example, you may want to change the timeout or retry times of an agent to meet changing network conditions or monitoring requirements.
To change one or more parameters in an existing Frame Relay agent definition, take the following steps:
Step 1 Launch Configuration Manager, if you have not already done so. See Chapter 4, "Configuration Manager."
Step 2 Select the FrameRelay radio button.
Step 3 Click Edit.
The Edit FrameRelay window opens. This window is the same as the Add FrameRelay Agent window, except that the fields are already filled in.
Step 4 Edit the fields. See "Adding Frame Relay Agents."
Step 5 Click OK to replace the original Frame Relay agent with the modified agent, or click Cancel to return to the Configuration Manager main window without modifying the agent.
Step 6 Select the Frame Relay agent you just modified and click Test to see if it can be reached. See Chapter 16, "Testing the Operational Status of an Agent."
As your network monitoring requirements change, you may no longer need to monitor a certain network segment. In this case, you might want to delete the Frame Relay agent from TrafficDirector. When you delete an agent from TrafficDirector, the actual agent remains connected to the network segment and continues to gather information, but TrafficDirector can no longer monitor the data it collects.
To delete a Frame Relay agent from TrafficDirector, take the following steps:
Step 1 Launch Configuration Manager, if you have not already done so. See Chapter 4, "Configuration Manager."
Step 2 Select the Frame Relay radio button.
Step 3 Select the Frame Relay agent you want to delete from the Agents list box.
Step 4 Click Delete.
Step 5 Click Yes to delete the agent, or click No to return to the Configuration Manger main window without deleting the agent.
For each DLCI you are monitoring on a Frame Relay interface, you can assign a name and download new CIR values to the agent. The name you assign to a DLCI is displayed in all TrafficDirector DLCI monitoring displays, for example, Traffic Monitor and All Talkers. The default DLCI name is DLCI-number. The CIR values that you specify are downloaded and configured in the agent when you click Download.
To edit the name and CIR values of a selected DLCI, take the following steps:
Step 1 Launch Configuration Manager, if you have not already done so. See Chapter 4, "Configuration Manager."
Step 2 Select the Frame Relay radio button.
A list of Frame Relay agents is displayed in the Agents list box.
Step 3 Select the Frame Relay agent for which you want to edit DLCIs.
Step 4 Click Learn to learn DLCIs on the selected Frame Relay agent.
A list of all discovered DLCIs is displayed in the DLCI list box (Figure 7-2).
Step 5 Select the DLCI you want to edit.
Step 6 Click Edit to the right of the DLCI list box.
The Edit DLCI window opens (Figure 7-3).
Step 7 Enter the following information:
Step 8 Click OK to accept the new DLCI configuration and map the name you specified to the selected DLCI, then go to Step 9 or click Cancel to close the Edit DLCI window without saving the new DLCI configuration.
The new CIR configuration is not downloaded to the agent until you click Download, as described in Step 9. and Step 10.
Step 9 Select the Frame Relay agent you are working with from the agents list box.
Step 10 Click Download.
TrafficDirector downloads the new CIR values specified in Step 7 to the selected agent.
