MACsec adapter EXTREME Feature Pack X620 for MACsec switching, hardware MAC Security support

EXTREME Feature Pack X620 is a MACsec adapter that enables MACsec switching on compatible network devices. It provides hardware-level MAC Security to encrypt and authenticate Ethernet link traffic, protecting point-to-point connections in enterprise and data center networks. The adapter integrates with existing switch platforms that support the EXTREME feature pack architecture and is intended to add link-layer encryption without altering higher-layer network services.

Advantages

The adapter implements MAC Security in hardware, reducing CPU overhead on the host switch and ensuring line-rate encryption for supported ports. It supports standard MACsec protocols for interoperability, while enabling secure Ethernet links that help satisfy regulatory and internal compliance requirements. Installation preserves existing network topology and management workflows, allowing administrators to centrally manage MACsec policies through the compatible switch software.

Suitable for

• Securing point-to-point Ethernet links between switches or between switch and server
• Enterprise campus networks requiring link-layer encryption for compliance
• Data center interconnects where hardware MACsec reduces latency and CPU load
• Environments needing interoperability with standard MACsec-capable devices

Key specifications

• Function: MACsec adapter enabling hardware-based link encryption and authentication
• Compatibility: Designed for compatible EXTREME switch platforms that accept feature pack modules
• Performance: Hardware offload for MACsec to maintain line-rate traffic on supported ports
• Protocols: Implements IEEE 802.1AE MACsec standards for encryption and integrity
• Deployment: Intended for point-to-point secure Ethernet links within enterprise and data center environments

How to use

Install the EXTREME Feature Pack X620 into a supported slot of a compatible switch following the hardware installation guidelines from the switch vendor. After physical installation, enable MACsec switching features through the switch operating system or management interface and configure MACsec policies, key agreements, and control plane settings as required. Verify link status and MACsec session establishment with connected peers and monitor performance and security logs through the normal management tools.

Usage recommendations

Use the adapter on links where end-to-end link-layer protection is required and where connected devices support MACsec to ensure interoperability. Maintain up-to-date switch software that includes necessary feature pack support and review key management policies regularly to align with compliance and security requirements.
