Running Tcl Script Before Router Reads startup-config

[rais]

Hi,

Is it possible to execute a script on a router that could run before router starts to read startup-config.  

Thanks.

Hello,

not sure if that is possible. You can register and run a TCL script upon reboot:

::cisco::eem::event_register_timer cron cron_entry @Reboot

What exactly are you trying to accomplish ?

Where do I have to save this statement?

::cisco::eem::event_register_timer cron cron_entry @Reboot

Trying to configure an ethernet interface + enable ssh/telnet after 'write erase' reboot on a remote device.

Thanks.

Hello,

the line is put at the top of the actual tcl script. Let's say your tcl script is called ssh_telnet.tcl. The first line would be:

::cisco::eem::event_register_timer cron cron_entry @Reboot

followed by the actual script you have configured.

On your router, you would configure the below:

event manager directory user policy flash:

event manager policy ssh_telnet.tcl authorization bypass

Edit: you need to save the tcl script to flash:
