arp-priority
This command is used to define the Allocation and Retention Priority (ARP) values of the QoS profile in PCC-QoS-Profile which is to use in Subscriber profile in PCC-Service instance on IPCF node.

Syntax
[no] arp-priority arp_priority pre-emption {capable | not-capable} {not-vulnerable | vulnerable}
no
Removes the configured ARP priority set for PCC-QoS-Profile for PCC-Service instance on IPCF node.
arp_priority
Specifies the priority value for ARP in a PCC-QoS-Profile which is to use in Subscriber profile in PCC-Service instance on IPCF node.
arp_priority must be an integer from 1 through 15.
pre-emption {capable | not-capable }
Sets the Pre-emption capability related parameters with ARP priority in PCC-QoS-Profile name which is to use in Subscriber profile in PCC-Service instance on IPCF node.
Pre-emption capability determines whether a bearer with a lower ARP priority level should be dropped to free up the required resources.
capable : This keyword indicates that the service data flow is allowed to get resources that were already assigned to another service data flow with a lower priority level.
non-capable : This keyword indicates that the service data flow is not allowed to get resources that were already assigned to another service data flow with a lower priority level.
{not-vulnerable | vulnerable }
Sets the Pre-emption vulnerability related parameters with ARP priority in PCC-QoS-Profile name which is to use in Subscriber profile in PCC-Service instance on IPCF node.
Pre-emption vulnerability determines whether a bearer is applicable for dropping by a pre-emption capable bearer with a higher ARP priority value.
not-vulnerable : This keyword indicates that the resources assigned to the service data flow shall not be pre-empted and allocated to a service data flow with a higher priority level.
vulnerable : This keyword indicates that the resources assigned to the service data flow can be pre-empted and allocated to a service data flow with a higher priority level.
Usage Guidelines
Use this command to define the ARP priority and pre-empt parameters in PCC-QoS-Profile which is to be used in Subscriber profile in PCC-Service instance on IPCF node.
ARP controls how the IPCF reacts when there are insufficient resources to establish the new RAB. Typically it manages it by; 1) Deny the RAB request and 2) Preempt an existing RAB and accept the new RAB request.
