Cisco HWIC-4ESW and HWIC-D-9ESW
EtherSwitch Interface Cards
This document provides configuration tasks for the 4-port Cisco HWIC-4ESW and the 9-port
Cisco HWIC-D-9ESW EtherSwitch high speed WAN interface cards (HWICs) hardware feature
supported on Cisco 1800 (modular), Cisco 2800, and Cisco 3800 series integrated services routers.
Cisco EtherSwitch HWICs are 10/100BaseT Layer 2 Ethernet switches with Layer 3 routing capability.
(Layer 3 routing is forwarded to the host, and is not actually performed at the switch.). Traffic between
different VLANs on a switch is routed through the router platform. Any one port on a Cisco EtherSwitch
HWIC may be configured as a stacking port to link to another Cisco EtherSwitch HWIC or EtherSwitch
network module in the same system. An optional power module can also be added to provide inline
power for IP telephones. The HWIC-D-9ESW HWIC requires a double-wide card slot.
This hardware feature does not introduce any new or modified IOS commands.
