1- and 2-Port Fast Ethernet High-Speed WIC for Cisco 1841, 2800, and 3800 ISR [Cisco 3800 Series Integrated Services Routers]

Overview

The Layer 3 Cisco® 1- and 2-Port Fast Ethernet High-Speed WAN interface cards (HWICs) (see Figures 1 and 2) supported on the Cisco 1841, Cisco 2800, and Cisco 3800 Series Integrated Services Routers offer small-to-large-sized businesses and enterprise branch-office customers the option to add Layer 3 routed ports with many advanced features, including quality-of-service (QoS) and rate-limiting capabilities.

Note: The 2-port (HWIC-2FE) card is offered on the Cisco 3800 Series Routers only. The 2-port card is not supported on the Cisco 1841 nor the Cisco 2800 Series Integrated Services Routers.

Note: For the HWIC-1FE and HWIC-2FE the minimum level is Cisco IOS 12.4(15)T.

Applications

The new HWICs provide additional Layer 3 routed ports with features equivalent to those on the motherboard of the integrated services routers. These Fast Ethernet interfaces can be used for physical LAN segregation, creation of a demilitarized zone (DMZ), or as a WAN interface. Broadband customers can use them to connect to an alternate provider that delivers service on an Ethernet port.

Figure 5 shows the HWIC being used to bridge nonroutable protocols while providing Layer 3 connectivity. The HWIC is also useful in situations that require IEEE 802.1q inter-VLAN.

Summary

The Cisco Fast Ethernet HWICs are singlewide interface cards, available as a 1-port HWIC (HWIC-1FE) and as a 2-port HWIC (HWIC-2FE), that provide Cisco modular and integrated services routers with additional Layer 3 routed ports.

Feature Highlights

The Fast Ethernet routed ports on the HWICs have the same characteristics and features as the onboard LAN interfaces for the integrated-services-router platforms. Along with Layer 3 connectivity, such as per-port access control lists (ACLs), routing, and IP addressing, these HWICs provide functions equivalent to those of onboard Fast Ethernet routed ports.
