Expanding Router Ports on 2811

The 2811 only has two Ethernet router ports. Is it possible to install a HWIC-4ESW and configure one or more of its four ports as router ports?

Do you mean LAN ports ? Yes.

"Q. What devices can you connect to the Cisco EtherSwitch HWICs?

A. You can connect many devices to the Cisco EtherSwitch HWICs, including:

? A PC or workstation

? An IP telephone

? Cisco Aironet? or third-party 802.11a/g-based access points or bridges

? A port on Cisco Catalyst switch or any third-party switch

? A Cisco CallManager

? Any device with a 10BASE-T/100BASE-TX interface

? Any device with a 10BASE-T/100BASE-TX interface with 802.3af-based in-line power requirements

? A hub or workgroup hub

Q. What is Ethernet switching?

A. Each Ethernet interface on the Cisco EtherSwitch HWICs can connect to a single workstation, server, or hub through which workstations or servers connect to the network. On a typical Ethernet hub, all ports connect to a common backplane within the hub and all devices attached to the hub share the bandwidth of the network. If two stations establish a session that uses a significant level of bandwidth, the network performance of all other stations attached to the hub is degraded. To reduce degradation due to collisions in a shared LAN, the Cisco EtherSwitch HWIC treats its Ethernet interface as a separate collision domain."
