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.

    Cisco HWIC-4ESW and HWIC-D-9ESW EtherSwitch Interface Cards How to Configure EtherSwitch HWICs Adding Secure Addresses The secure address table contains secure MAC addresses and their associated ports and VLANs. A secure address is a manually entered unicast address that is forwarded to only one port per VLAN. If you enter an address that is already assigned to another port, the switch reassigns the secure address to the new port.
