Cisco IOS Upgrade Question...

k1gaudineer

Good afternoon...  I am hoping that this is a quick question..  I have been through a lot of post here and the help for getting a working config script to upgrade my Cisco IOS devices has been great.  I need to add one tweak to a script.  I have a lot of switch stacks at one location.  Some are running the image version we want to standardize on and others are not.  I have all of the switch stacks at this location in an NCM group.

I would like to add one more piece of logic to my script so that the only devices that are upgraded are the stacks that are not running the image we want to standardize on.  Right now I am using the script below and trying to add the line in red  as a second condition.  This is just in case a node that is running the proper image is selected it won't be upgraded.  But when I add the second line the script fails. 

Any suggestions on how to add a second condition to the script?

string @CommandLine = 'archive download-sw /overwrite tftp://$@{StorageAddress}/' + @IOS_FILENAME

//Make sure there are no spaces in filename

if (@IOS_FILENAME contains ' ')

{}

else

{

  foreach ( @node in @ContextNode )

  {

      if ( @node.Vendor == 'Cisco' ) 

      if ( @Node.SysDescr contains 'Cisco IOS Software, Version 12.2' )

    {

        CLI

        {

          @CommandLine

        }

    }

  }

}

}

The way I interpret the logic in how the script the first if does not actually have any steps to preform and the second one then does it, that is why it fails I believe.You can try it like the below which should work like how you intended it to. It will loop through all nodes, if the vendor is Cisco it will then check if the SysDescr contains 'Cisco IOS Software, Version 12.2' and if it does then it will run your command line, if not it will not do anything. The system description has to contain that exact phrase in it though which is what you need to be careful of, so if there is anything in between IOS Software and the Version it will not match the contain and it will not run as it will not contain that string if that makes sense. Anyway give this one a shot.

string @CommandLine = 'archive download-sw /overwrite tftp://$@{StorageAddress}/' + @IOS_FILENAME

//Make sure there are no spaces in filename

if (@IOS_FILENAME contains ' ')

{}

else

{

  foreach ( @node in @ContextNode )

  {

      if ( @node.Vendor == 'Cisco' )

   {

         if ( @Node.SysDescr contains 'Cisco IOS Software, Version 12.2' )

  {

  CLI

  {

  @CommandLine

  }

  }

   }

  }

}
