Issue with Whitespace and banners

mark.healey

I'm having issues pushing a new banner to our Cisco devices using a config change script.

If I tick the "keep whitespace" box the script always fails with "Connection Refused", even though the banners are uploaded to the switch.

Because it fails, it's never written to NVRAM.

If I don't tick the box, the script succeeds, so the changes are written to NVRAM, but the formatting is lost.

Any ideas?

Template below

/*

.CHANGE_TEMPLATE_DESCRIPTION

        Change to Standard Config on Cisco IOS devices

.CHANGE_TEMPLATE_TAGS

  Cisco

.PLATFORM_DESCRIPTION

        Cisco IOS

.PARAMETER_LABEL @ContextNode

        NCM Node

.PARAMETER_DESCRIPTION @ContextNode

        The node the template will operate on.  All templates require this by default. The target node is selected during the first part of the wizard so it will not be available for selection when defining values of variables.

*/

script StandardConfigCiscoIOS (

                                           NCM.Nodes @ContextNode       )

{

  CLI

  {

    configure terminal

This is going to be a very ugly suggestion, but it should work. Create a variable for each line of the banner and then just call the variable. You will probably need an enter variable so I would see it looking something like the below. When inserting the below section of a template it did verify, but I wasn't able to fully test the it. Let me know if this works for you.

Edit: Forgot to mention this method should also make updating the banners a lot easier.
