High-Speed Multigigabit Module for Catalyst 8000 Edge Platforms
The Cisco C-NIM-8M is a high-performance Network Interface Module designed to elevate the capabilities of Cisco Catalyst 8300 and 8200 Series Edge Platforms. Engineered for modern, high-bandwidth branch environments, this module integrates switching and routing into a single unit, offering eight Multigigabit (mGig ports capable of speeds up to 2.5 Gbps.
This module is essential for branches deploying Wi-Fi 6/6E access points, cellular gateways, and high-performance endpoints that require robust power and speed. With integrated UPOE+ (802.3bt, it delivers up to 90W of power per port on four designated ports, eliminating the need for external power injectors.
Key Features and Strategic Advantages
-
2.5G Multigigabit Connectivity: Future-proof your branch with 8 ports supporting 100M/1G/2.5G speeds, optimizing performance for high-speed uplinks and local devices. (Note: 10M connections are not supported.
-
90W UPOE+ Power Delivery: Ports 4, 5, 6, and 7 are compliant with IEEE 802.3bt, providing up to 360W total power to support power-hungry IoT devices and advanced Access Points.
-
Flexible WAN/LAN Architecture: The two highest-numbered ports (6 and 7 are "Flex Ports" that can be toggled to native Layer 3 WAN mode, offering full feature parity with onboard Catalyst 8000 WAN ports.
-
Enterprise-Grade Security: Features full IEEE 802.1AE MACsec encryption (128-bit and 256-bit for LAN, and WAN MACsec with Tag-in-Clear support on Layer 3 ports, ensuring data integrity across the network. Includes Cisco TrustSec SGT support.
-
Seamless SD-WAN Integration: Fully compatible with Cisco Catalyst SD-WAN Manager (vManage release 20.12 and later for centralized orchestration and automated policy management.
Deployment Scenarios
-
High-Density Branch Offices: Consolidate switching and routing in a single chassis to reduce Total Cost of Ownership (TCO and simplify management.
-
Wi-Fi 6 Infrastructure: Utilize 2.5G mGig ports to prevent bottlenecks when connecting next-gen Wireless Access Points.
-
Secure Edge Networking: Implement end-to-end segmentation and encryption using MACsec and TrustSec Security Group Tagging (SGT.
-
Hybrid WAN Access: Leverage the L3 Flex ports to terminate high-speed Ethernet WAN links directly into the module.
