Template show commands fro stack switching

[a.short]

Does anyone know of a way to run a show command from a template & creating a variable from a the output (depending on the output format)  to be used elsewhere in the template.

I am trying to determin te number of switches in a stack to allow interface configs to be generated & applied.

Or is this not possible in templating?

You can't really run a show command, but you can leverage system variables.  The system variable $__device.serialNumber will give you a list of all the serial numbers.  You can then do a "for loop" to loop through the list and generate interface commands on each iteration.

Will it tell me the number of switches in a stack?

I can't find anything the systems vars that could help me .

[Preston Chilcote]

The number of switches in the stack is the number of serial numbers listed in the  $__device.serialNumber system variable.

Here's some VTL code to get you started:

#set( $stack_serial_numbers = $__device.serialNumber.split(",") )

#set( $stack_member_count = $stack_serial_numbers.size() )
