Feature Information
The 4-port Cisco HWIC-4ESW and the 9-port
Cisco HWIC-D-9ESW EtherSwitch high speed WAN
interface cards (HWICs) hardware feature is 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.
