Limitations
The WPS Prioritization feature has the following limitations:
-
In a multi-Sx/N4 scenario, all Control Plane nodes must use the same process to send MP values. This applies to SMF/cnSGW and PGW-C/SGW-C working with the same UPF.
-
The sessions recovered during the UPF software upgrade will retain their prioritization values. As a result, after the UPF upgrade between N-1 and N, the prioritization for existing sessions will not work as expected, and the show CLI output will be undetermined.
-
In the case of a configuration change at the SMF that changes existing priority values or a configuration change at the UPF that changes the session type, the session type and priority are not re-evaluated. As a result of such a configuration change, incorrect statistics updates may occur.
-
Due to any mid-session priority changes, some of the statistics may be inconsistent.
