Quality of Service (QoS) attributes for a 5G QoS identifier (5QI) table

You can configure the Quality of Service (QoS) attributes for a 5G QoS identifier (5QI) value in the 5QI table. The Access and Mobility Function (AMF) sends N2 messages to the Access Gateway Function containing the 5QI value. The 5QI value corresponds to Junos CoS parameters. AGF inspects the N2 and N1 messages for 5QI and QoS Flow ID (QFI) values and matches those values to parameters in the 5QI table. AGF can then update data packets with an updated differentiated services code point (DSCP) in the payload to match the derived QoS parameters. 

You can set the following QoS attributes for a 5QI value in the 5QI table: 

•  Differentiated Services code point (DSCP) value 
•  DSCP value for the N3 interface 
•  Forwarding class 
•  Loss Priority 

To set the QoS attributes, use the set services agf fiveqi-map identifier upstream-rewrite statement.
