The Lenovo XClarity Controller (XCC), an embedded management processor, utilizes several ports for various management and communication functions. These ports facilitate secure web access, API communication, and remote presence capabilities.
The primary ports used by XClarity Controller (XCC) include:
Port Name | Port Number (Default) | Fixed or Configurable | Purpose |
---|---|---|---|
HTTPS | 443 | Configurable | Secure web-based access to the XCC management interface. |
REST over SSL | 443 | Fixed | Provides secure API access for programmatic management and automation. |
CIM/XML HTTPS | 5989 | Configurable | Used for Common Information Model (CIM) and XML-based management. |
Remote Presence | 3900 | Configurable | Facilitates remote console (KVM over IP) and virtual media functions. |
Understanding XCC Port Usage
The XClarity Controller serves as the next-generation management controller for Lenovo servers, providing robust remote management capabilities. Understanding the specific ports it uses is crucial for network configuration and security.
- HTTPS (Port 443): This is the standard secure port for web traffic. By default, XCC uses it for its web interface, allowing administrators to access settings, monitor status, and perform actions through a graphical user interface. While 443 is the default, this port is configurable, meaning an administrator can change it to another port if necessary for network policies or security.
- REST over SSL (Port 443): Also utilizing port 443, this is dedicated to the Representational State Transfer (REST) API. This allows for automated management and integration with other tools or scripts, enabling efficient infrastructure management at scale. This port is fixed and cannot be changed.
- CIM/XML HTTPS (Port 5989): This port is used for management protocols based on CIM and XML, which are common standards for managing hardware and software assets across different vendors. This port is configurable, offering flexibility in network deployments.
- Remote Presence (Port 3900): This port is essential for remote KVM (Keyboard, Video, Mouse) access and virtual media functionalities. It allows administrators to view the server's console remotely, interact with the operating system installation, or mount virtual media (like ISO images) as if they were physically present at the server. This port is also configurable.
It is important to ensure that these ports are open on firewalls and accessible from management networks to allow proper functionality and remote management of your Lenovo server infrastructure.
