High-Speed WAN Interface Cards to the Network
Revised: 04/20/2009, OL-12851-01
This guide describes how to connect Cisco 1- and 2-Port Fast Ethernet high-speed WAN interface cards
(HWICs) to your network. It contains the following sections:
• Cisco 1- and 2-Port Fast Ethernet HWICs, page 1
• Connecting Fast Ethernet HWICs to a Network, page 4

• Obtaining Documentation, Obtaining Support, and Security Guidelines, page 5
Cisco 1- and 2-Port Fast Ethernet HWICs
The Cisco Fast Ethernet HWICs are single-wide 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 line-rate Layer 3 routed ports. (See the “Fast Ethernet HWICs Supported
Platforms” section on page 2.)
Fast Ethernet HWICs Standards
The Fast Ethernet HWICs are designed in accordance with IEEE 802.3 10BASE-T Ethernet and IEEE
802.3u 100BASE-TX Fast Ethernet standards.
The following IEEE standards are also supported:
• 802.1p
• 802.1u
• 802.1x
Fast Ethernet HWICs Restrictions
The following features are not supported on the Fast Ethernet HWICs:
• Cisco Interswitch Link (ISL) tagging
