Cisco C-NIM-WAN-4S | Cisco 8000 Series Secure Routers 4-Port Gigabit SFP WAN Module, 256-bit MACsec

Q: Which Cisco router platforms support the C-NIM-WAN-4S module?
A: The C-NIM-WAN-4S is supported on Cisco 8000 Series Secure Routers with available NIM slots, specifically the C8231-E-G2, C8235-E-G2, and C8375-E-G2 platforms. It is installed in NIM slots only and is not supported in the SM-NIM Carrier Adapter.

Q: What are the primary use cases for this WAN module?
A: The C-NIM-WAN-4S is designed for expanding WAN capacity in enterprise environments, providing diverse fiber-based connections, bandwidth aggregation across multiple links, and robust link redundancy. It integrates seamlessly with SD-WAN deployments and advanced security features for optimized enterprise connectivity.

Q: Does the C-NIM-WAN-4S support Layer 2 switching?
A: No, the C-NIM-WAN-4S is a dedicated Layer 3 WAN module exclusively designed for routing functionality. If you require Layer 2 LAN/WAN capabilities with SFP ports, consider the C-NIM-4X module for Catalyst 8300 platforms instead.

Q: What security features are included with this module?
A: The module supports 256-bit WAN MACsec encryption for secure point-to-point connectivity and includes MAC filtering capabilities. It leverages the 8000 Series router's advanced security and SD-WAN intelligence for comprehensive network protection.

Q: Can I install multiple C-NIM-WAN-4S modules in a single router?
A: Yes, you can deploy as many modules as the platform slot density allows. For example, the C8375-E-G2 can support up to three C-NIM-WAN-4S modules in any combination when using the C-SM-NIM-ADPT carrier adapter.
