Gigabit Ethernet Applications
Figure 2 shows an ISR G2 with two EHWICs: one connected to the branch-office LAN, and one connected to an EWAN service. On the LAN side, the card can run multiple VLANs to segregate LAN networks. On the EWAN side, it can segregate traffic using multiple VPN types. Cisco IOS Software enables HQoS applications such as traffic shaping and Network-Based Application Recognition (NBAR). As with VLAN trunking, this configuration is well suited for situations in which fiber connectivity is desirable while providing the flexibility of an RJ-45 copper connection.
