How to check Cisco router Hardware and License information

A Comprehensive Guide to Checking Cisco Router Hardware and License Information

Cisco routers are the backbone of many networks, ensuring that data flows efficiently and securely. To manage and maintain these routers effectively, it’s essential to have a clear understanding of the hardware components and licenses associated with them. In this guide, we will walk you through the steps to check your Cisco router’s hardware and license information.

Part 1: Checking Hardware Information

Knowing the hardware specifications of your Cisco router is crucial for troubleshooting, upgrading, and capacity planning. Here’s how you can check it:

Step 1: Access the Command Line Interface (CLI)

Using a terminal emulator like PuTTY or HyperTerminal, establish a console or SSH connection to your Cisco router.

Step 2: Log In

Log in with the appropriate credentials (username and password) to access the router’s command-line interface.


Step 3: View Hardware Details

Now, enter the following command:

show hardware

show hardware

This command will display detailed information about the router’s hardware components, including the CPU, memory, interfaces, and modules.

Step 4: Review the Output

Examine the output to gather information about the router’s hardware components, including their names, models, and installed quantities. Pay special attention to items like the CPU type, available RAM, and the number and types of interfaces.

Part 2: Checking License Information

Cisco routers often require licenses to unlock specific features or capabilities. To check your router’s license information, follow these steps:

Step 1: Access the CLI (if not already connected)

If you are not already connected to the router’s command-line interface, follow the same steps as in Part 1.

Step 2: View License Information

Enter the following command to view license information:

show license

Step 3: Interpret the Output

The command will display a list of licenses installed on your router. Each license will have a unique identifier, description, and expiration date (if applicable). Make sure to check the license type and ensure it covers the features you need.

Additional Tips

  • To get more detailed information about a specific hardware component, you can use commands like show interfaces, show memory, or show version.
  • If you need to install or update licenses, consult Cisco’s documentation or your Cisco representative for guidance on the licensing process.
  • Regularly checking hardware and license information is essential for maintaining your network’s health and ensuring you have the necessary resources and capabilities to support your operations.


Being able to check Cisco router hardware and license information is a fundamental skill for network administrators and IT professionals. By following the steps outlined in this guide, you can gain valuable insights into your router’s capabilities and licensing status, empowering you to make informed decisions and keep your network running smoothly.
