Service Ingress QoS Policy Commands
A maximum of eight lsp-exp rules are allowed on a single policy.
Values
fc fc-name — The value given for the fc-name parameter 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 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.
The sub-class-name parameter is optional and used with the fc-name parameter to define a preexisting
sub-class. The fc-name and sub-class-name parameters must be separated by a period (dot). If sub-
class-name does not exist in the context of fc -name, an error will occur.
Values
Default
priority — The priority parameter is used to override 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 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.
high — The high parameter is used in conjunction with the priority parameter. 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.
low — The low parameter is used in conjunction with the priority parameter. 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
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
