Connecting Power to the Router

Step 2 Connect the other end of the cable to a port on the hub, switch, or the Ethernet port on your computer.

Note The example provided in Figure 2-3 on page 2-6shows connectivity to a hub. The router’s Ethernet switch port can be connected to other networked devices, such as a switch or computer with a NIC. If you are connecting the router’s switch port to another switch, use a crossover cable.

Note If you are connecting a computer to the router’s switch port, it will take about 30 seconds for connectivity to be established due to the Spanning-Tree Protocol (STP) disabling the ports until a loop-free topology is determined. When you use this type of connection, you must configure the spanning-tree portfast command on the router’s switch port. The spanning-tree portfast command causes a spanning tree port to enter the forwarding state immediately, bypassing the listening and learning states.

Caution You can use the portfast feature on switch ports that are connected to a single workstation or PC only to allow those devices to connect to the network immediately, rather than waiting for spanning tree to converge. Do not use the portfast feature on ports that are connected to networking devices such as hubs, routers, switches, bridges, or concentrators.
