CISCO Ethernet switch interface

Cisco® Gigabit Ethernet Enhanced High-Speed WAN Interface Cards

The 4- and 8-port Cisco EtherSwitch® 10/100/1000 Gigabit Ethernet EHWICs are Power over Ethernet (PoE)-capable integrated EHWIC switches for the Cisco Integrated Services Routers Generation 2 (ISR G2) routers. The Cisco Gigabit Ethernet EHWICs have either four or eight 10/100/1000 switched Gigabit Ethernet ports, with options for PoE support on all ports. The cards provide line-rate Layer 2 switching across the Gigabit Ethernet ports, using Cisco IOS® Software embedded in Cisco Catalyst® switches.

Features such as port autosensing, IEEE 802.1p, quality of service (QoS), VLAN trunking with 802.1Q, and 802.1d Spanning Tree Protocol are standard on the EHWIC switch. The PoE version of the EHWIC switch can power IEEE 802.3af-compliant devices such as Cisco IP Phones, Cisco wireless access points, or any other device with a power draw of up to 20W.

The EHWIC switches enable Cisco's industry-leading power initiatives, Cisco EnergyWise, Cisco Enhanced Power over Ethernet (ePoE), and per-port PoE power monitoring.

Cisco IOS Software on Cisco Catalyst switches allows network administrators to manage a single device using Cisco management tools or the router command-line interface (CLI) for LAN and WAN management, in addition to delivering a consistent user experience at branch offices.
