I am very new to automation and have been trying to use the Python SDK for ACI (acitoolkit) for creating specific vlan into a pre-existing vlan pool. I looked at the learning labs and saw that there are functions in the acitoolkit that are being used to create tenants, VRF, BD, etc. like following but I couldn't find one to create vlan inside a vlan pool. Could anyone please guide how to do that? Thanks.
