How to get a value from an interface and use it to configure the device in a script

Have you looked at the 'Change VLAN Membership on Cisco IOS Ports' config change template? There is also detailed documentation in the admin guide on how to arrive at this template

You modified script would look something like

/*

.CHANGE_TEMPLATE_DESCRIPTION

       Insert your description here

.CHANGE_TEMPLATE_TAGS

        Cisco, IOS, VLAN Membership

.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.

.PARAMETER_LABEL @TargetPorts

        Select Port(s)

.PARAMETER_DESCRIPTION @TargetPorts

        Select the port(s) for which you would like to change VLAN membership.

.PARAMETER_LABEL @VlanToAssign

        VLAN to assign

.PARAMETER_DESCRIPTION @VlanToAssign

        Select the VLAN you would like to assign.

script BLAHBLAHBLAH(  

                                          NCM.Nodes @ContextNode,

                                          NCM.Interfaces[] @TargetPorts,

                                          NCM.VLANs @VlanToAssign          )

{

  // Enter configuration mode

  CLI

  {

  configure terminal

  }

  // Loop through selected ports

  foreach (@portItem in @TargetPorts)

  {

    CLI

    {

      interface @portItem.InterfaceDescription

    }

    CLI

    {

      switchport access vlan @VlanToAssign.VLANID

      authentication event server dead action authorize vlan @VlanToAssign.VLANID

    }

    CLI

    {

      exit

    }

  }

  // Exit configuration mode

  CLI

  {

    exit

  }

}

Thanks for the quick reply, I need to explain some more, the vlan config is already on the interface so need to take that vlan and use it for the next command.

So pre change the config is

interface GigabitEthernet1/0/2

switchport access vlan 10

and post change it should be

interface GigabitEthernet1/0/2

switchport access vlan 10

authentication event server dead action authorize vlan 10

Cheers

‌if you look at the config change templates section of the admin guide, you will find a list of entities and properties you can reference in the script. vlanid is of the properties for an interface object. In the script body above, you can reference this as

@portItem.InterfaceDescription

your script body will also expect only 2 parameters - NCM.Nodes and NCM.Interfaces

‌also meant to add, if you go to the ncm tab and click on the inventory view, you can run the interfaces report and make sure it does contain vlanid ad expected.

I'm happy with selecting the node and interfaces and I can configure these with the script. The vlan.id through I'm not sure what you mean, it's not an svi but physical and we have a voice vlan too. 

Thanks.

A solution that works, but can take a long time to configure is to create a rule for every VLAN. This is the only solution that I have come up with so far. It was still better than trying to login to a 1000 devices or however many you manage and manually update each one.
