产品概览

Cisco ^® Catalyst ^® 8000 千兆以太网 WAN 模块为 Catalyst 8300 和8200 系列边缘平台。

这些模块取代了 Cisco 4000 系列集成多业务路由器支持的网络接口模块 (NIM) 和单宽增强服务模块 (SM-X) 以太网 WAN 模块。这些模块提供最大的灵活性，可加速以太网 WAN 访问、思科 SD-WAN 以及其他与 LAN、架顶式数据中心交换机和服务器的高速连接选项等应用。从第一天起，所有这些模块都提供对 SD-WAN 和 vManage 的支持。

这些模块上的端口用作路由的第 3 层端口。路由器的嵌入式 WAN 端口支持的所有功能也可用于这些 WAN 模块。

不支持模块上的本地端口之间或模块上的端口与路由器系统内的其他端口之间的第 2 层交换。这些模块上的端口终止来自外部连接交换机的第 2 层中继。因此，第 2 层中继和 VLAN 信息不会传递到系统中的其他端口。主机路由器路由进入这些模块的所有流量。

C-NIM-1M 模块支持以太网供电（PoE IEEE 802.3 af/at/bt）。

该数据表还涵盖了用于 Catalyst 8300 系列的 SM-NIM 载体适配器。此载卡使语音、WAN 和 LAN 模块的所有组合都可以热插拔并在服务模块 (SM) 插槽中运行。每个载卡最多支持 2 个 NIM，没有任何性能或功能限制。

思科提供三种以太网 WAN 模块：

Cisco 1-port 10-Gbps/1-Gbps WAN with 256-bit WAN MACsec (C-NIM-1X)

The C-NIM-1X is a next-generation 10G Layer 3 WAN module. This module provides high-speed WAN connectivity through a single SFP+ port supporting 1-Gbps and 10-Gbps WAN connections. The 10-Gbps WAN connection is a non-oversubscribed connection, since it’s connecting to the backplane using a 10-Gbps link. Full 256-bit WAN MACsec is supported.

The C-NIM-1X does not support SFP transceivers for RJ-45 copper media, nor does it support 100BASE/10BASE SFP modules. The module is supported on all Catalyst 8300 Series platforms. It is not supported on the Catalyst 8200 Series platforms.

Figure 2.            

Cisco 2-port 100-Mbps/1-Gbps WAN NIM with 256-bit WAN MACsec (C-NIM-2T)

The C-NIM-2T is a dual combo port module with two RJ-45 copper line ports and two SFP fiber ports. The ports on this NIM are configured in two port groups with one RJ45 port and one SFP port in each group. One port from each group can be configured for simultaneous use, providing flexibility in the selection of media for WAN connectivity. The RJ-45 ports support 100BASE-TX and 1000BASE-T copper connections. The SFP ports support 100BASE-FX and 1000BASE-X fiber connections. The module supports 256-bit WAN MACsec. The C-NIM-2T is supported on the Catalyst 8200 Series, 8200L, and all 8300 Series platforms.

Figure 3.            

Cisco 1-port 2.5-Gbps/1-Gbps WAN NIM with UPOE (C-NIM-1M)

The C-NIM-1M is a single-port 2.5-Gbps BASE-T port module with Cisco UPOE+ (90W).

Its single copper port supports 100/1000/2500BASE-T connections, popularly called a Multigigabit (mGig) port. This module also supports Cisco UPOE+ (802.3bt, up to 90W), which can be used for powering a cellular gateway directly from the host router. The C-NIM-1M is supported on the Catalyst 8200 Series, 8200L, and all 8300 Series platforms.

Figure 4.            

Cisco single-wide service module carrier card for 2x NIMs (C-SM-NIM-ADPT)

The C-SM-NIM-ADPT is a dual-NIM carrier card in an SM-X form factor for Catalyst 8300 Series platforms. This module supports a wide variety of NIMs, including the C-NIM Layer 3 WAN modules for the Catalyst 8000 platforms. See Table 6 for a list of supported modules. Since it connects to the backplane with two 10-Gbps links, this carrier card will not impose any bottleneck on traffic, even if two 10-Gbps C-NIM-1X modules are installed. It supports full online insertion and removal. There is no upper limit on the number of C-SM-NIM-ADPT cards that can be installed in a Catalyst 8300 Series platform, other than available SM-X slots.

Features

The Cisco Catalyst 8000 Gigabit Ethernet WAN Modules are based on the technology of the onboard Gigabit Ethernet and SFP/SFP+ ports of the Cisco Catalyst 8000 Edge Platforms. Feature support will therefore be identical to that of the onboard ports on the Catalyst 8300 and 8200 Series and the 8200L.
