DNAC Templates - pushing delta config only

Hi,

 

When pushing Day-N templates, we notice that DNAC pushed the entire template to the devices, instead of only the changes/additions that we have made to the template.

 

Is there a way to push only the delta config to the network devices?

Many thanks

Gert

This is something in road map as part of model based template , so probably you will see this in future as of now we don't have any.

There are ways around this. For many commands there is no issue with adding commands that already exist. However for things like a VTY ACL you may get kicked out. To avoid this you can do something like the following:

line vty 0 15

no access-group SSH

no ip access-list standard SSH

ip access-list standard SSH

permit host 1.1.1.1

deny any

line vty 0 15

access-group SSH

 

You can do similar things for other issues that DNAC has an issue with. DNAC does not like if NTP is already there and will fail when you push the template if it already exists. For that simply remove ntp and then add the commands back similar to the ACL example above.

 

I hope that this is helpful,

Chuck
