C-NIM-1X Description

The C-NIM-1X is a Cisco Catalyst 8000 Gigabit Ethernet WAN module for Catalyst 8300 Series edge routers that terminate 10G Ethernet WAN circuits. The module has one SFP+ port that runs at 1G or 10G as a routed Layer 3 interface, reaches the forwarding engine over a non-oversubscribed 10G backplane link and supports 256-bit WAN MACsec. The module requires Cisco IOS XE 17.3.2, does not install in Catalyst 8200 or 8200L routers, and accepts neither copper RJ-45 SFPs nor 100M or 10M SFP modules.

Application Scenarios

10G Carrier Ethernet Handoff

At a regional office where the service provider delivers a 10G Ethernet circuit on fiber, the module’s SFP+ port terminates the circuit as a routed interface on the Catalyst 8300 and can encrypt the link with 256-bit WAN MACsec.

Routed Link To A Top-Of-Rack Switch

A Catalyst 8300 at the edge of a small server room can connect to the top-of-rack switch over a 10G optic or direct-attach cable. VLAN trunks from that switch end on the router port, and the router routes every packet it receives there.

17.6.1

C-NIM-1X and C-NIM-4X both run SFP+ optics at 1G or 10G over a 10G backplane connection, but C-NIM-1X carries a single routed WAN port with 256-bit MACsec, while C-NIM-4X has four ports with WAN MACsec limited to the last two. A Catalyst 8300 that needs more than one fiber port in a single NIM slot takes the four-port module, which requires Cisco IOS XE 17.11.1 against 17.3.2 and fits only a direct NIM slot. Catalyst 8200 and 8200L routers take neither SFP+ module, so a 1G fiber or copper circuit there runs on C-NIM-2T, which keeps 256-bit MACsec. A 2.5G copper handoff, or an endpoint powered from the router at up to 90W, needs C-NIM-1M, which has no MACsec.

Ordering Checklist

  • Catalyst 8300 hosts: C8300-1N1S-4T2X, C8300-1N1S-6T, C8300-2N2S-4T2X and C8300-2N2S-6T take the module in a NIM slot. Catalyst 8200, 8200L and Cisco 4000 Series ISR routers do not support it.
  • SM slot through C-SM-NIM-ADPT: Add a C-SM-NIM-ADPT carrier when the module goes in an SM slot or must be removable with the router running. A direct NIM slot allows online insertion only, not online removal.

Questions & Answers

  • Can two C-NIM-1X modules share one C-SM-NIM-ADPT without a bandwidth bottleneck?

    Yes. C-SM-NIM-ADPT connects to the Catalyst 8300 backplane with two 10-Gbps links, so two C-NIM-1X modules on one carrier are not bottlenecked. Each module keeps its own SFP+ port at 1G or 10G, so a branch can terminate two 10G circuits behind one service-module slot of the router.
  • Is C-NIM-1X supported under SD-WAN management on a Catalyst 8300?

    Yes. The Catalyst 8000 WAN NIM data sheet lists SD-WAN and vManage support for C-NIM-1X from day 1. The module needs Cisco IOS XE 17.3.2 and installs only in Catalyst 8300 Series routers such as C8300-2N2S-4T2X, so plan the controller side of the SD-WAN deployment around that platform before ordering the module.
  • Is C-NIM-1X compatible with Cisco 4000 Series ISR routers?

    No. C-NIM-1X is specific to Catalyst 8300 edge platforms and is not compatible with Cisco 4000 Series ISRs, per the Catalyst 8300 and 8200 ordering guide. Use it in C8300-1N1S-6T, C8300-1N1S-4T2X, C8300-2N2S-6T or C8300-2N2S-4T2X, and keep any ISR 4000 router in the same site on its own NIM family.
  • Can C-NIM-1X be removed while a Catalyst 8300 is running?

    Not from a direct NIM slot, which allows online insertion only. Fit C-NIM-1X in a C-SM-NIM-ADPT carrier when it must be removable with the router running. The carrier is also the route into an SM slot, and the module requires Cisco IOS XE 17.3.2 on the router either way, so the carrier choice does not change the software plan.
