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
Syntax Description
[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.
Example
Following command sets the ARP Priority
2 with preemption capability and
vulnerability in PCC-QoS-Profile instance on IPCF node.
arp-priority 2 pre-emption capable vulnerable
