How to Configure Inter-Controller Monitoring234

Monitoring the health and performance of your network devices is essential for maintaining a reliable and efficient network. In this article, we will discuss how to configure inter-controller monitoring (ICM) on your Cisco network devices. ICM allows you to monitor the status of other controllers in your network, ensuring that they are all functioning properly and that there is no single point of failure.

Prerequisites

Before you can configure ICM, you must first ensure that the following prerequisites are met:* All controllers in the network must be running the same version of software.
* All controllers must be able to communicate with each other over the management network.
* A RADIUS server must be configured to provide authentication for the ICM connections.

Configuration

To configure ICM, follow these steps:1. On each controller, enable ICM by entering the following command in the CLI:
```
controller monitoring inter-controller enable
```
2. Configure the RADIUS server information by entering the following commands in the CLI:
```
radius-server host
radius-server key
```
3. Configure the ICM connections by entering the following commands in the CLI:
```
controller monitoring inter-controller connection
```
4. Repeat step 3 for each controller that you want to monitor.
5. Verify that ICM is functioning properly by entering the following command in the CLI:
```
show controller monitoring inter-controller status
```

Monitoring

Once ICM is configured, you can monitor the status of other controllers in the network by using the following commands in the CLI:* `show controller monitoring inter-controller status` - This command displays the status of all ICM connections.
* `show controller monitoring inter-controller statistics` - This command displays statistics for all ICM connections.

Troubleshooting

If you are having problems with ICM, you can troubleshoot the issue by using the following commands in the CLI:* `debug controller monitoring inter-controller` - This command enables debugging output for ICM.
* `show debug controller monitoring inter-controller` - This command displays the debugging output for ICM.

Conclusion

ICM is a valuable tool that can help you to ensure the reliability and performance of your network. By following the steps outlined in this article, you can configure ICM on your Cisco network devices and monitor the health of your network from a single location.
