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 nonroutable
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.
