Please Consider the below points :
1) DHCP sets the extension tag. Once the TC accesses the network and obtains the dynamic IP, it will be automatically added to the TCM.
2) After the TC is added to the TCM, it will be automatically moved to the client group with the bound IP address segment.
3) you can create a template delivery or file upgrade policy in the policy center. The policy needs to be bound to the client group. This will automatically perform configuration or upgrade tasks for the TCs in the group.
