Apstra comes with predefined device profiles, however in certain situations user might want to create custom device profiles

Predefined device profiles in Apstra are immutable therefore If the user needs to update any field, they must clone the DP and update the cloned DP.

There are two different types of device profiles in Apstra:

Monolithic Device Profiles: A monolithic DP are suitable for single chassis hardware which doesn't have a chassis profile or linecard profiles.

Modular Device Profiles: A modular DP is composed from a chassis profile (CP) and a list of linecard profiles (LPs). A predefined modular DP is thus composed from a predefined CP and list of predefined LPs. Predefined CP and predefined LPs are immutable. If the user wants to make changes to a predefined modular DP, they must clone the underlying predefined CP and/or predefined LPs, make changes to those clones, and then create a new user-defined modular DP from those cloned components.

In order to understand more about device profiles and creation of device profiles, User can follow the below documentation below specific to the Apstra release:
