On the 7210 SAS-R6 and 7210 SAS-R12, only unicast traffic sent out of RVPLS SAPs uses per-SAP egress queues. BUM traffic sent out of RVPLS SAPs uses per-port egress queues.
The Service Egress policy defines the Service Level Agreement (SLA) for service packets as they egress on the access SAP. Service Egress QoS policies allow the definition of queue parameters along with a remark policy.
Service Egress Qos policies are available for use only when per SAP egress queues (SAP-based queuing mode) are used. It is not available when port-based queuing mode (that is, with per access port egress queues) is in use.
The 7210 SAS-Mxp, 7210 SAS-R6, and 7210 SAS-R12, on port egress, use either port-based egress queuing and shaping or SAP-based egress queuing and shaping for all SAPs configured on the port. The config system global-resource-profile qos port-scheduler-mode command on the 7210 SAS-R6 and 7210 SAS-R12 and the config system resource-profile qos port-scheduler-mode command on the 7210 SAS-Mxp allows the user to select the mode for all SAPs configured on either access ports or hybrid ports. When port-scheduler-mode is enabled, the software allocates eight egress queues per port (access port or hybrid port). See Schedulers on 7210 SAS-R6 and 7210 SAS-R12 for more information. When port-scheduler-mode is disabled, the software allocates eight egress queues per SAP, which are configured using service egress policies.
