Switches: IOS

Packet Tracer uses a simplified model of the Cisco IOS. Click on the CLI tab in the switch configuration window to access the Cisco IOS command line interface for the switch. Use the Copy and Paste buttons to copy and paste text to and from the command line. This page lists the Cisco IOS command tree for Packet Tracer switches. For the Cisco Catalyst 3560-PS switch with Layer 3 capabilities, refer to the "Router IOS" page for additional commands. The tree contains only Cisco IOS command chains that are supported in Packet Tracer.
