A little help getting started please

[Darren Starr]

I have been coding massive amounts of TCL scripts for IOS and frankly, now that I'm comfortable with TCL as a language I want to make the next move. I have not been able to find a good starting point just yet to make the jump.

I am currently waiting for a copy of the Cisco TCL programmer guide (found a used one) to show up in the mail, but this will take nearly a month.

Can someone take the following script :

  foreach a [ list 6 7 8 9 79 80 81 82 83 84 85 86 87 ] {

  clear line $a

}

And help me convert this so that if I type :

host# clearlab

on the CLI, it will trigger the script and for each "[confirm]" message that shows up, it sends a carriage return.

So far, I have found that I need to register an EEM event (not so hard) and I'll need to import the Cisco libraries. I believe I'll need to also save this to flash using puts [ open...

Any help would be immensly appreciated!

What is the event you want to use to trigger the clear line?

[Darren Starr]

Joseph,

Thanks for the response.

As mentioned above... I'd like to make use of the CLI event of a user typing clearlab

You could do an applet like:

event manager environment vty_lines 6 7 8 9 79 80 81 82 83 84 85 86 87

event manager applet clear-vtys

event cli pattern "^clearlab" enter

action 000 cli command "enable"

action 001 foreach a $vty_lines

action 002  cli command "clear line $a" pattern "confirm"

action 003  cli command "y"

action 004 end

[Darren Starr]

Certainly! But it wouldn't help me to learn how to properly trigger TCL scripts from the command line

I only recommended that particular example randomly. I actually plan to use it as a template to hopefully do much grander things

Thanks a lot for this one though, it is also going into my library under "sometimes simple tasks are best done simple"

You can take that applet to http://www.marcuscom.com/convert_applet to get the EEM Tcl version.  The results from that site can give you an EEM Tcl policy that you can register and trigger using the same clearlab command.
