Cisco HWIC-4ESW and HWIC-D-9ESW
EtherSwitch Interface Cards
First Published: May 17, 2005
Last Updated: April 15, 2006
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 10/100BASE-T 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 Cisco IOS commands.
Finding Feature Information in This Module
Your Cisco IOS software release may not support all of the features documented in this module. To reach
links to specific feature documentation in this module and to see a list of the releases in which each feature is
supported, use the “Feature Information for the Cisco HWIC-4ESW and the Cisco HWIC-D-9ESW
EtherSwitch Cards” section on page 117.
Finding Support Information for Platforms and Cisco IOS Software Images
Use Cisco Feature Navigator to find information about platform support and Cisco IOS software image
support. Access Cisco Feature Navigator at http://www.cisco.com/go/fn. You must have an account on
Cisco.com. If you do not have an account or have forgotten your username or password, click Cancel at
