Each queue in a policy is associated with one of the forwarding classes. Each queue can have its
individual queue parameters allowing individual rate shaping of the forwarding class(es) mapped
to the queue.
The forwarding class determination per service egress packet is determined at ingress. If the
packet ingressed the service on the same router, the service ingress classification rules determine
the forwarding class of the packet. In network mode, if the packet was received over a service
transport tunnel on a network port, the forwarding class is typically determined by in the MPLS
LSP EXP bits. For 7210 SAS M in access uplink mode, if the packet was received on a access-
uplink port, the forwarding class is determined by the Dot1p bits in the outer tag of the QinQ
encapsulation.
Access egress QoS policy ID 1 is reserved as the default access ports which do not have another
access egress policy explicitly assigned. The characteristics of the default policy are listed in the
following table.
7210 SAS M OS Quality of Service Guide
A unique service access QoS policy ID.
A QoS policy scope of template or exclusive.
The parameters that can be configured for a queue are discussed in
page 45.
IEEE 802.1p priority value remarking based on forwarding class.
In the 7210 SAS M in network mode and access-uplink mode, remarking of dot1p or
DSCP or both bits by default is disabled. It can be enabled by the remarking command
with options to remark dot1p/dscp/both present under access-egress context. All customer
traffic containing IEEE 802.1p or DSCP or both encapsulation will be marked according
to the default FC-Dot1p or DSCP marking map if Dot1p or DSCP values are not explicitly
configured.
