WIC-4ESW Card This section describes the 4-port 10/100BASE-TX Ethernet switch interface card (WIC-4ESW) and how to connect it to a network. The following subsections are included: • WIC-4ESW Interface Card Port Numbering, page 2 • WIC-4ESW Interface Card Processor Requirements, page 3 • WIC-4ESW Interface Card Supported Standards, page 3 • WIC-4ESW Interface Card Platform Limitations, page 3 The WIC-4ESW interface card is a Layer 2 Ethernet switch with Layer 3 routing capability. (Layer 3 routing is forwarded to the host, and is not actually performed at the switch.) The ports autosense the speed (10 Mbps or 100 Mbps) and duplex mode (full- or half-duplex) of the device to which it is connected and then operates at the same speed and in the same duplex mode.
