Cisco Integrated Management Controller (CIMC) is a crucial component for managing and monitoring Cisco UCS servers, including those used for Cisco Identity Services Engine (ISE). CIMC provides a robust management interface that allows administrators to control, configure, and monitor the server hardware independently of the operating system or hypervisor installed.
What is CIMC?
CIMC is an embedded management service that provides out-of-band management for Cisco UCS C-Series servers. It functions similarly to other management tools like HP's iLO or Dell's iDRAC, offering a web-based interface, command-line access, and integration with standard management tools.
How Does CIMC Work?
CIMC operates independently of the server’s operating system, meaning it can be accessed even when the server is powered off, provided it’s connected to a power source and network. It allows administrators to perform essential tasks such as:
Monitoring hardware status and health (CPU, memory, power, and temperature)
Configuring BIOS settings remotely
Accessing the server console for troubleshooting
Updating firmware and managing server power state
Configuring CIMC
To configure CIMC, follow these steps:
Connect to CIMC Interface: Access CIMC via its dedicated management port using a web browser or SSH client.
Initial Setup:
Set up network configuration: IP address, subnet mask, and default gateway.
Configure user accounts for secure access.
Configure BIOS and Boot Order: Adjust BIOS settings and boot order directly from the CIMC interface to ensure optimal performance and compatibility with Cisco ISE.
Monitor and Manage: Utilize CIMC’s real-time monitoring capabilities to keep track of hardware health, resource usage, and potential faults.
Advantages of Using CIMC with Cisco ISE
Out-of-Band Management: Manage the server remotely even when the main OS is down, ensuring continuous oversight of Cisco ISE deployments.
Enhanced Security: Manage access controls, BIOS, and firmware updates remotely, reducing on-site interventions.
Resource Optimization: Real-time monitoring and control help in optimizing server performance, identifying potential hardware issues early, and ensuring high availability of Cisco ISE services.
Firmware Management: Easily update and manage server firmware without impacting running services, improving operational efficiency.
Using CIMC with Cisco ISE greatly enhances server management capabilities, ensuring that your Cisco ISE deployments remain secure, optimized, and efficiently managed. For further details on configuring and leveraging CIMC, refer to the Cisco documentation or consult with your network management team.
