This document summarizes basic commands for Cisco switches in both IOS and CLI formats. It covers commands for configuration, interfaces, VLANs, trunking, VTP, and Spanning Tree Protocol. The document provides the equivalent commands for basic settings and functions across both formats to assist users in operating Cisco switches in either command line interface.
