Service Egress and Ingress QoS Policies

Quality of Service Guide
3HE 11014 AAAC TQZZA Edition: 01
A maximum of 64 DSCP rules are allowed on a single policy. The specified name
must exist as a dscp-name. Table 46 lists all the valid DSCP names.
fc-name — the value given for fc-name must be one of the predefined forwarding
classes in the system. Specifying the fc-name is optional. When a packet matches
the rule, the forwarding class is only overridden when the fc-name parameter is
defined on the rule. If the packet matches and the forwarding class is not explicitly
defined in the rule, the forwarding class is inherited based on previous rule matches.
Values be, l2, af, l1, h2, ef, h1, nc
Default inherit (when fc-name is not defined, the rule preserves the previous
forwarding class of the packet)
priority — this keyword overrides the default enqueuing priority for all packets received
on an ingress SAP using this policy that match this rule. Specifying the priority is
optional. When a packet matches the rule, the enqueuing priority is only overridden
when the priority keyword is defined on the rule. If the packet matches and priority
is not explicitly defined in the rule, the enqueuing priority is inherited based on
previous rule matches.
Default inherit
high — this keyword is used in conjunction with the priority keyword. Setting the
enqueuing parameter to high for a packet increases the likelihood of enqueuing the
packet when the ingress queue is congested. Ingress enqueuing priority only affects
ingress SAP queuing; once the packet is placed in a buffer on the ingress queue, the
significance of the enqueuing priority is lost.
Default high
low — this keyword is used in conjunction with the priority keyword. Setting the
enqueuing parameter to low for a packet decreases the likelihood of enqueuing the
packet when the ingress queue is congested. Ingress enqueuing priority only affects
ingress SAP queuing; once the packet is placed in a buffer on the ingress queue, the
significance of the enqueuing priority is lost.
Default low
