Description

The Cisco C-NIM-1X is a Layer 3 WAN expansion module for Catalyst 8300 Series routers, delivering high-speed fiber connectivity through a single SFP+ port supporting 1G and 10G speeds. With hardware-based 256-bit MACsec encryption and a non-oversubscribed 10 Gbps backplane connection, this NIM is ideal for secure SD-WAN deployments, enterprise WAN uplinks, and high-bandwidth branch connectivity. The module requires a compatible NIM slot on Catalyst 8300 platforms and supports Cisco 1G/10G SFP and SFP+ transceivers.

FAQs

Q: Which Cisco router platforms support the C-NIM-1X module?
A: The C-NIM-1X is supported exclusively on Catalyst 8300 Series routers, including models like C8300-1N1S-4T2X, C8300-1N1S-6T, C8300-2N2S-4T2X, and C8300-2N2S-6T. It is not compatible with Catalyst 8200 Series platforms.

Q: What types of transceivers can I use with the C-NIM-1X?
A: The C-NIM-1X supports Cisco 1 Gbps SFP and 10 Gbps SFP+ fiber transceivers. It does not support copper SFP modules (RJ-45 SFP transceivers) or legacy 100BASE or 10BASE SFP modules.

Q: Does the C-NIM-1X support MACsec encryption?
A: Yes, the C-NIM-1X provides hardware-based 256-bit WAN MACsec (IEEE 802.1AE) encryption, making it suitable for secure WAN and SD-WAN deployments requiring Layer 2 encryption between sites.

Q: Is the C-NIM-1X oversubscribed on the backplane?
A: No, the C-NIM-1X connects to the router backplane via a dedicated 10 Gbps link, ensuring full non-oversubscribed throughput for 10 Gbps WAN connections.

Q: Can I install multiple C-NIM-1X modules in a single router?
A: Yes, if your Catalyst 8300 router has multiple NIM slots available. For example, the C8300-2N2S-4T2X has two NIM slots. You can also use the C-SM-NIM-ADPT carrier card to add two NIM modules in a single SM-X slot.
