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.
Overview
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.
