Service SAP QoS Policy Command Reference
priority — The priority parameter is used to override the default enqueuing priority for all
high — The high parameter is used in conjunction with the priority parameter. Setting the
low — The low parameter is used in conjunction with the priority parameter. Setting the
hsmda-counter-override counter-id — The hsmda-counter-override reclassification action is
mac-criteria
Syntax [no] mac-criteria
Context config>qos>sap-ingress
Description
The mac-criteria based SAP ingress policies are used to select the appropriate ingress queue and
corresponding forwarding class for matched traffic.
This command is used to enter the node to create or edit policy entries that specify MAC criteria.
Router implementation will exit on the first match found and execute the actions in accordance with
the accompanying action command. For this reason entries must be sequenced correctly from most to
least explicit.
The no form of this command deletes all the entries specified under this node. Once mac-criteria
entries are removed from a SAP ingress policy, the mac-criteria is removed from all services where
that policy is applied.

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 parameter 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.
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.
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 No override.
optional and only has significance on SAPs which are created on an HSMDA. When
specified, packets matching the MPLS EXP value will be mapped to the defined HSMDA
exception counter-id for the packets queue group. The default behavior is to use the default
counter on the queue group for the queue to which the packet is mapped. The specified
counter-id must be specified as an integer between 1 and 8. To remove the HSMDA exception
counter reclassification action for the specified lsp-exp-value, the lsp-exp command must be
re-executed without the hsmda-counter-override reclassification action defined. This
parameter only applies to the 7450 ESS and 7750 SR.
