SPI sharing per session

If QoS handling or accounting per-IPoE or per-PPPoE session is required, then the SPI sharing is configured to per-session sharing in the SLA profile:

Example:

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

Per-session sharing applies to PPPoE sessions and IPoE sessions (enabled on the group interface). An IPoE host setup fails when IPoE sessions are disabled on the group interface and per-session sharing is configured.

Each IPoE or PPPoE session from the same subscriber, active on the same SAP and having the same SLA profile assigned, has its own set of queues and policers. Per-session SPI sharing is depicted in Figure: SLA profile instance per session.
