Product Overview

Overview (EHWIC-4ESG)

Cisco EHWIC-4ESG Ethernet Enhanced High-Speed WAN Interface Card equips with  4 * 10/100/1000 switch ports to integrate with Cisco Integrated Services Routers Generation 2 (ISR2).  EHWIC-4ESG provides layer 2 switching features such as port autosensing, IEEE802.1P, IEEE802.1x, SNMPV1,V2,V3, QoS, VlAN trunking, STP. The new feature of Gigabit Ethernet EHWIC includes: 8 QoS queues per port, Shaped Deficit Weighted Round Robin (SDWRR), dynamic secure port, intrachassis cascading. When connecting with Multigigait Fabric (MGF)-enabled modules in the system acting as a single switch, directly forwards the layer 2 switching packets in the system without utilizing CPU. EHWIC also supports redundancy protocol such HSRP, VRRP and BLGP.

The new Cisco EHWIC card offers IP routing, and voice gateway capability into a single chassis to accommodate;the needs for high traffic data from the small to medium-sized business or enterprise branch-office. The EHWIC does not support routed ports, however, assign each switch port to its own VlAN providing some equivalence to routed port, this features handled by software-based SVI interfaces may cause serious performance issues and limitations.

EHWIC expands the switching capacity for ISR2 routers with cascading capabilities in order to enhance routers performance. The integration of ISR G2 routers deduce network complexity, simplify network management, lower maintenance costs and deliver consistent user experience.

Marketing Information

When inserted in a Cisco 1900, 2900, or 3900 Series ISR, the Gigabit Ethernet EHWICs provide a fully integrated, secure networking and converged IP communications solution. From a single platform with an integrated switch, you can connect IP phones, wireless access points, and IP-based video cameras to your network and power them using the IEEE 802.3af or Cisco ePoE. 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 and place the users in the appropriate VLAN or Cisco TrustSec™ group. As the end-user data leaves the LAN, the router can then encrypt the traffic and place it on a multitude of VPNs, securing the communications among branch offices and central sites.
