Cisco EHWIC-D-8ESG

Product Description

The 4- & 8-port Cisco Gigabit Ethernet Enhanced High-Speed WAN interface cards (EHWICs) can reduce your company's total cost of ownership (TCO) by integrating Gigabit Ethernet (GE) switch ports within Cisco 3900, 2900, & 1900 Series Integrated Services Routers (ISRs). These low-density Gigabit Ethernet switches offer small to medium-sized business (SMB) & enterprise branch-office customers a combination of switching & routing integrated into a single device (Figure 1). Integration of these switches with Cisco IOS Software allows network administrators to manage a single device using Cisco management tools or the router comm&-line interface (CLI) for LAN & WAN management needs. This approach reduces network complexity, lowers maintenance contract costs, & lessens staff training needs. It also simplifies software qualification efforts & delivers a consistent user experience at branch offices. in addition, these low-density Gigabit Ethernet switching modules enable Cisco's industry-leading power initiatives, Cisco Energy Wise, Cisco Enhanced Power over Ethernet (e Po E), & per-port Power over Ethernet (Po E) power monitoring, which enhance the ability of the branch office to scale to higher performance requirements & still meet environmental initiatives for IT teams to operate a power-efficient network. The 4- & 8-port Gigabit Ethernet EHWICs provide line-rate Layer 2 switching across onboard Gigabit Ethernet ports. The 4-port Gigabit Ethernet EHWIC has four 10/100/1000 switch ports, with options for Po E support on all four ports. The 8-port Gigabit Ethernet EHWIC has eight 10/100/1000 switched Gigabit Ethernet ports, with a Po E support option on all 8 ports. The new features for the Gigabit Ethernet EHWICs include: 8 quality-of-service (Qo S) queues per port, Shaped Deficit Weighted Round Robin (SDWRR), dynamic secure port, intrachassis cascading, up to 20W of Po E per port, & Po E per-port monitoring & policing. Multigigabit Fabric (MGF) is enabled for direct module-to-module communication. Secure Network Connectivity for Data, Voice, & Video When inserted in a Cisco 1900, 2900, or 3900 Series ISR, the Gigabit Ethernet EHWICs provide a fully integrated, secure networking & converged IP communications solution. From a single platform with an integrated switch, you can connect IP phones, wireless access points, & IP-based video cameras to your network & power them using the IEEE 802.3af or Cisco e Po E. With the optional integration of Cisco Unified Communications Manager Express, the router can also provide call processing for the phones. As users attempt network access, the Gigabit Ethernet EHWIC can use IEEE 802.1x to validate the credentials of the end device & place the users in the appropriate VLAN or Cisco Trust Sec™ group. As the end-user data leaves the LAN, the router can then encrypt the traffic & place it on a multitude of VPNs, securing the communications among branch offices & central sites.
