Chapter 8 Data Models and Dynamic Templates

apply to all devices in the [CAMPUS-DISTRIBUTION] group in hosts.ini these variables are processed first and, unless overridden by another variable, such as a host variable, will remain the configured value.

The next example covers the CAMPUS-DISTRIBUTION.YML file. This is the data model dictionary for all devices in the [CAMPUS-DISTRIBUTION] group in the hosts.ini file. Enforce the following standards to all devices that act as distribution switches on the network:

 Standard Cisco Catalyst 4500 hardware platform.  Standard QoS model using MQC.  Standard port-channel 1 uplink to core.  Standard port-channel 50 and 60 for VSS.  Standard interface for Dual Active Detection (DAD) port.  Standard port-channel 100 for legacy, spanned, layer 2 VLANS to the core.  Unknown port-channel numbers / access switches downstream (variable or non-standard).
