|Product Description:||Cisco Four port 10/100/1000 Ethernet switch interface card|
|Product Type:||Interface Module|
|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.|

The Cisco® Gigabit Ethernet Dual-Identity Enhanced High-Speed WAN Interface Card (EHWIC) brings both Small Form-Factor Pluggable (SFP) and copper (RJ-45) Gigabit Ethernet connectivity to Cisco Integrated Services Routers (ISRs) to accelerate applications such as Ethernet WAN access, inter-VLAN routing (IVR), and high-speed connectivity to LAN switches.
The single-port Cisco Gigabit Ethernet EHWIC provides Gigabit Ethernet optical and copper connectivity in a compact form factor to the Cisco Integrated Service Router Generation 2 (ISR G2).
The Gigabit Ethernet EHWIC enables branch offices to cost-effectively use high-speed uplinks in numerous environments (Figure 1). The enhanced performance of Gigabit Ethernet in Cisco ISR G2 routers enables new applications and services and provides greater capacity for existing IVR and bridging capabilities. Branch offices can now connect to Ethernet WAN (EWAN) Layer 2 and 3 services.
Note: The EHWIC provides Gigabit Ethernet connectivity but will not support line rate since throughput is limited by the platforms. The maximum throughput cannot exceed 800 Mbps bidirectionally.
For flexibility, the EHWIC includes one SFP slot, which supports a Cisco SFP (see Table 1 later in this document) and a copper RJ-45 port, where either the SFP port (operating at 100/1000 Mbps) or the RJ-45 (operating at 10/100/1000 Mbps) port can be active at one time. The SFP port supports digital optical monitoring (DOM) as specified by the industry-standard SFF-8472 multisource agreement (MSA). This feature enables the end user to monitor real-time parameters of the SFP, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.
Cisco IOS® Software provides enhanced capabilities such as hierarchical quality of service (HQoS), Multiprotocol Label Switching (MPLS), IP Security (IPsec), and Layer 3 VPNs. Since this is a true routed port card, the user can configure an IP address directly on the EHWIC-1GE-SFP-CU interface and does not have to configure the port for VLAN trunking as is done in switched virtual interface (SVI) configurations.
