Connecting 1- and 2-Port Fast Ethernet 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 • Related Documents, 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 OL-12851-01 1
