Additional PoE features include:
●
Per-port power consumption control allows you to specify a maximum power setting on an individual port.
●
Per-port PoE power sensing measures the actual power being drawn, enabling more intelligent control of
powered devices.
●
The Cisco PoE MIBs provide proactive visibility into power usage and allow you to set different power-level
thresholds.
●
Cisco Discovery Protocol Version 2 allows the Cisco EHWICs to negotiate a more granular power setting
than IEEE classification provides when connecting to a Cisco powered device such as IP phones or access
points.
Multigigabit Fabric
The EHWIC switch has a gigabit connection to the MGF and transparently integrates into the system. Connecting
over the MGF enables the EHWIC switch to directly communicate with other MGF-enabled modules in the system
without involving CPU. Layer 2 switching of packets is thus either internal to each EHWIC switch or goes through the
MGF when multiple MGF-enabled modules are in the system. The router CPU is not involved in this operation
(Figure 2).

Applications
Small and Medium-Sized Branch Offices
The Cisco Gigabit Ethernet EHWICs in a small to medium-sized enterprise branch-office data deployment scenario
provide the flexibility of integrated routing and switching functions in one device. This scenario allows the deployment
of high-speed connections between individual network resources such as client desktops, servers, IP phones,
wireless access points, and video devices from a single device and at the same time allows for WAN connectivity at
Layer 3 through the router (Figure 3).
