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.
Figure 2. VLAN Trunking Application
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.
