SPI sharing per SAP

By default, all subscriber sessions or hosts from the same subscriber, active on the same SAP and with the same SLA profile assigned, share an SPI. The default SPI sharing is per SAP, as depicted in Figure: SLA profile instance per SAP.

With SPI sharing per SAP, traffic from all subscriber sessions on a specific SAP and with the same SLA profile associated are mapped to the same set of queues and policers for QoS handling. Statistics from these queues and policers are also used in accounting. Per-host or per-session accounting modes cannot report counters for individual sessions unless their traffic is mapped in separate queues.

SPI sharing per SAP is the default configuration in an SLA profile and applies to PPPoE sessions, IPoE sessions (enabled on the group-interface) and IPoE hosts (IPoE sessions are disabled on the group-interface):

Example:

    configure 
        subscriber-mgmt 
            sla-profile "sla-profile-1"
                def-instance-sharing per-sap
