QoS Policies

used to evaluate how buffers from the pool are allocated to different FCs and to in-profile and out-
of-profile traffic within a given FC. The slope policies define the WRED parameters to use for in-
profile/high-priority packets and for out-of-profile/low-priority packets. The high-slope and low-
slope define the parameters for in-profile/high-priority packets and for out-of-profile/low-priority
packets respectively.
Remark policies are applied to access SAP egress and access-uplink port egress. They are not
directly associated with the SAP and access-uplink port egress. Instead they are associated with
service egress policy and network qos policy. They define the forwarding class and profile to
egress marking values (for example: IEEE 802.1p bits in the Ethernet VLAN tag) to use.
One service ingress QoS policy and a single service egress QoS policy can be applied to a specific
access SAP. One network QoS can be applied to a specific access-uplink port. One network queue
policy can be applied to the access uplink port. If no QoS policy is explicitly applied to a SAP or
port, a default QoS policy is applied.
Dot1p classification and DSCP classification allows user to define the map of Dot1p bits and IP
DSCP values to forwarding class and assign the profile for the packet on access SAP ingress and
access-uplink port ingress.
