Talk:Dell Dimension 2400 with Broadcom 4401 Onboard NIC/Cisco Catalyst 2950 Switch

That's an issue with the switch configuration, not FOG. Any network card will have the same issue. When you use 802.1d version of spanning tree protocol (the default), you want to enable portfast on all switchports that are not used for uplink or as trunk ports. Otherwise, the port takes about 40-50 seconds to reach active status. To do this, go into interface configuration mode for the port and just type "switchport portfast" and press enter.

The other solution is to use rapid spanning tree protocol, 802.1w. It's definitely a better protocol. To do this, in global configuration mode, type "spanning-tree mode rapid-pvst" and press enter. Either one of these should solve the problem.
