1. Please use the Java Inventory Manager for Configuration Management and you will find the templates i'm talking about.
As i'm writing this, on the right side of my screen your own website links to similiar questions about the EMC.
2. My observation is indeed that Extrem tries to emulate the functions of the "configuration Templates" via the sites "Defaults".
3. Proof reading your documentation under
http://documentation.extremenetworks.com/netsight/8.0/9035088-01_EMC_8.0_EMC.pdf
on page 1360:
Restoring a Configuration
Using a configuration template allows you to restore a complete or partial
configuration to the device with variables you can define specifically for that
device. If you are going to use a configuration template for your device, you
must
create the Configuration Template to use as the source configuration for a
device.
"create the Configuration Template" is a link to page 213,....named: "Editing an Archive" but no where in the following pages is any word about templating a configuration.
