How to copy a Cisco Catalyst Switch Configuration?

I have four Cisco Catalyst 3550 Switches. I have one of the configured and working. I would like to copy the configuration from the one that is working, and "paste" it to the other three. The only thing I need to change is the TCP/IP address. All four switches will be part one the same LAN, connected via fiber optic cable, using GBICs, on the same VLAN. Step by step directions for the "copy and paste" would be perfect. I would also need to know how to change the TCP/IP address, after "pasting" the configuration to each of the other three switches.

you can try to use ftp or tftp server to upload configuration, however, it is rather handy to use just show running-config feature from cli (with enough buffer set for telnet/ssh window) and literaly copy-paste config from one window, to notepad, where you will edit it and then to a second switch where you just paste that config from "configure terminal" mode.

Don't have FTP or TFTP server. I can display running config but, not sure how to complete your instructions. Would you please list a "step by step" explaination?

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
