• If sap-qos-marking is enabled, the FC to dot1p marking configured in the SAP egress policy is used for
remarking traffic sent out of SAPs associated with L2 services. Traffic sent out of SAPs associated with
L3 services and B-SAPs configured in PBB B-VPLS service is not marked.
• If sap-qos-marking is disabled, the access-egress policy is used for remarking for all the traffic sent out
of the access port. It includes all SAPs configured on the access ports and associated with L2 VPN ser

vices, L3 services, and PBB B-SAPS. Port-based marking must be enabled to ensure packets are
marked. The user has an option to use dot1p, DSCP, or dot1p + DSCP values for marking. For more
information, see the 7210 SAS-X QoS guide.
The behavior on hybrid ports is as follows:
• If sap-qos-marking is enabled, then the FC to dot1p values configured in the sap-egress policy is used
for remarking traffic sent out of SAP configured in L2 services. Traffic sent out of SAPs associated with
L3 services, B-SAPs configured in PBB B-VPLS service and network IP interface (that is, IP and
MPLS traffic sent out of network IP interface) is not marked.
• If sap-qos-marking is disabled, network port policy is used for marking all the traffic. It includes traffic
sent out of SAPs configured in L2 services, SAPs configured in L3 services, BSAPs configured in PBB
BVPLS service, and network IP interface (that is, IP and MPLS traffic sent out of network IP interface).
For MPLS traffic, only Dot1p bits are marked and for the rest use has an option to mark either dot1p or
DSCP bits. For more information, see the 7210 SAS-X QoS guide.
NOTE: Packets belonging to SAPs configured in a L2 service will also have their DSCP values marked
when remarking is enabled on a port and DSCP marking values are configured. Hence, it is recommended to
use only dot1p marking, when SAPs belonging to both L3 VPN service and L2 VPN service are configured
on the port.
Default Refer to Default values for sap-qos-marking in access and hybrid port modes on page 140 for more
information.
Parameters enable — Keyword used to enable port based marking for all SAPs on an access port and hybrid port.
disable — Keyword used to disable port based marking for all SAPs on an access port and hybrid port.

Description Platforms Supported: 7210 SAS-X.
This command is used to specify the mode of the access egress port scheduler. It operates in the following
two modes :
•fc-based
• sap-based
In the "fc-based" mode the priority of all egress queues across all SAPs are considered to determine the next
queue to be scheduled.
