Cisco HWIC-4ESW and HWIC-D-9ESW EtherSwitch Interface Cards First Published: May 17, 2005 Last Updated: July 28, 2010 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 Your software release may not support all the features documented in this module.
