SMF and UPF Interactions

UPF supports subscriber monitoring using CLI configurations to enable monitor subscriber per UE. However, when there are multiple UPFs in the network, it requires the users to enable monitor subscriber for a UE in all the UPFs, or wait for the UE to attach and identify the UPF, which is handling it and enable monitor subscriber on that UPF.

This feature enables monitor subscriber on UPF based on the configurations on SMF, thereby, eliminates the risk of missing captures.
