configured for each object (in a similar way to link mode). A Vport used together with an
egress port scheduler is supported with a LAG in port-fair mode, whereas it is not
supported with a distribute mode LAG.
This mode can be considered a mix of link and distributed mode. The mode uses the
configured hashing for LAG/SAP/service to choose either link or distributed adapt-qos
modes. The mode allows:
→ SLA enforcement for SAPs that through configuration are guaranteed to hash to a
single egress link using full QoS per port (as per link mode)
→ SLA enforcement for SAPs that hash to all LAG links proportional distribution of
QoS SLA amongst the line cards (as per distributed mode)
→ SLA enforcement for multi service sites (MSS) that contain any SAPs regardless of
their hash configuration using proportional distribution of QoS SLA amongst the line
cards (as per distributed mode)
The feature requires chassis mode D.
LAG mode must be access or hybrid.
The operator cannot change from adapt-qos distribute include-egr-hash-cfg to adapt-
qos distribute when link-map-profiles or per-link-hash is configured.
The operator cannot change from adapt-qos link to adapt-qos distribute include-egr-
hash-cfg on a LAG with any configuration.
