Chapter 1 Lab 1-1, Tcl Script Reference and Demonstration Instructor
Version Topology
Objectives
• • Use Tcl scripts to verify full connectivity. Identify causes of failures.
Background
The Cisco IOS Scripting feature provides the ability to run Tool Command Language (Tcl) commands from the Cisco IOS command-line interface (CLI). Tcl scripts can be created to accomplish routine and repetitive functions with Cisco IOS-based networking devices. In this lab, you create and execute a Tcl script that sends pings to multiple IP addresses in the network to test overall network connectivity. Note: Cisco IOS Release 12.3(2)T and later supports Tcl scripting.
Required Resources
• • 2 routers (Cisco 1841 with Cisco IOS Release 12.4(24)T1 Advanced IP Service or comparable) Serial and console cables
Note: This lab uses Cisco 1841 routers with Cisco IOS Release 12.4(24)T1 and the advanced IP image c1841-advipservicesk9-mz.124-24.T1.bin. Other routers (such as a 2801 or 2811) and Cisco IOS Software versions can be used if they have comparable capabilities and features. Depending on the router model and Cisco IOS Software version, the commands available and output produced might vary from what is shown in this lab.
