Place only one IP address per line. • Open the commands.txt file and enter the commands for configuration or commands for fetching configuration from the devices. Please note that the commands need to be compatible on all the devices entered in the ip.txt file. Please put in the commands in sequential order as you would configure the device in the normal circumstances.
For eg: terminal length 0 show running-config config t enable secret cisco exit terminal length 24 write memory • Please place the commands that are required after authentication is done. The script expects a device prompt (which can be customized easily) by default after authentication.
You may change it at any point of time. • Execute the file ttpmacro.exe present in the Tera Term directory and select the macro '.ttl’ extension.
• Please enter the Username for logging into the devices and press OK. Please note the Username and Password prompt would appear only once. The same username and password would be used to login into all the devices. • Please enter the password in the Password Prompt Dialog Box and press OK.
• For Enable Password Authentication Prompt, click yes if you have enable password authentication configured in atleast some of the devices or click no if you don’t have enable password configured in any of the devices. • If yes, then provide the enable password to log into all the devices. The password is assumed to be common on all the devices. • For the Logging Dialog Box.
Click yes if you want to log the output or click no if you don’t want to log the output. • If yes, enter the directory in which the logs have to be placed. For eg: If the directory is ‘C: logs’ then enter it in the following format: c: logs • Please note that the ‘ ’ sign is important after you enter the directory path and name. • Sit back and relax, as the commands entered in the commands.txt file is executed in every device entered in ip.txt. P.S.: While fetching configuration from any device like that of Cisco, please make sure to keep the terminal length to zero so that the device prompt appears immediately after the execution of the command. Please give your feedbacks to make it better.
