The Cisco® Gigabit Ethernet High-Speed WAN Interface Card (HWIC) brings Gigabit Ethernet connectivity to Cisco Integrated Services Routers routers to accelerate applications such as Metro Ethernet access, inter-VLAN routing, and high-speed connectivity to LAN switches.
The single-port Cisco Gigabit Ethernet HWIC provides Gigabit Ethernet optical and copper connectivity in a compact form factor for all Cisco Integrated Service Routers (ISRs).
The Gigabit Ethernet HWIC enables branch offices to cost-effectively use high-speed uplinks in numerous environments (Figure 1). The enhanced performance of Gigabit Ethernet in Cisco ISRs to enable new applications and services, as well as provide greater capacity for existing inter-VLAN routing and bridging capabilities. Additionally, branch offices can now connect to metropolitan-area networks (MANs).
Note: The HWIC provides Gigabit Ethernet connectivity but will not support line rate since the throughput is limited by the platforms.
For flexibility, the HWIC includes one Small Form-Factor Pluggable (SFP) slot to carry any Cisco copper or optical SFP (Table 1), allowing customers to use different SFPs for special distance, cost, existing infrastructure, and future expansion requirements.
® Software provides enhanced capabilities such as quality of service (QoS), 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 HWIC-1GE-SFP interface and does not have to configure the port for VLAN trunking as is done in Switched Virtual Interface (SVI) configurations.

Gigabit Ethernet Applications
Gigabit Ethernet in the Branch Office
In a branch office, the Cisco Gigabit Ethernet HWIC provides a high-speed uplink. Figure 2 shows the HWIC being used to bridge non-routable protocols, while providing Layer 3 connectivity. The HWIC is also useful in situations that require IEEE 802.1q inter-VLAN routing and in any LAN requiring fiber connectivity.

Gigabit Ethernet in MANs
Figure 3 shows the Cisco Gigabit Ethernet HWIC used to connect Layer 3 VPNs over a MAN. Cisco IOS Software enables QoS applications such as traffic shaping and Network-Based Application Recognition (NBAR). As with VLAN trunking, this is ideal for situations in which fiber connectivity is desirable.
