EHWIC-4ESG Overview
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).
The Features
Figure 1 shows the EHWIC-4ESG.
☆ 4 × 10/100/1000 switch ports
☆ Layer 2 switching features such as port autosensing, IEEE802.1P, IEEE802.1x, SNMPV1,V2,V3, QoS, VlAN trunking, STP
☆ 8 QoS queues per port, Shaped Deficit Weighted Round Robin (SDWRR), dynamic secure port, intrachassis cascading
☆ Supports redundancy protocol such HSRP, VRRP and BLGP
☆ 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.

| 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. | |
