 # Template files for generating minigraph.xml are defined in template/topo directory

 # To generate and deploy minigraph for SONiC switch matching the VM topology please use following command
-# ansible-playbook -i lab config_sonic_basedon_testbed.yml -l sonic_dut_name -e vm_base=VM0300 -e topo=t0 [-e deploy=true]

 # Parameters
 # -l str-msn2700-01          - the sonic_dut_name you are going to generate minigraph for
 # -e vm_base=VM0300          - the VM name which is used to as base to calculate VM name for this set
 # -e topo=t0                 - the name of topology to generate minigraph file
+# -e testbed_name=vms1-1     - the testbed name specified in testbed.csv file 
+#                              (if you give 'testbed_name' option, will use info from testbed and ignore topo and vm_base options)

 # -e save=True               - if save the newly generated minigraph to the targent DUT as starup-config, default is false if not defined
