Interface SAP Filter and QoS Policy Commands
egress
Syntax egress
Context config>service>vprn>if>sap
config>service>vprn>sub-if>grp-if>sap
Description This command enables the context to configure egress SAP Quality of Service (QoS) policies and
filter policies.
If no sap-egress QoS policy is defined, the system default sap-egress QoS policy is used for egress
processing. If no egress filter is defined, no filtering is performed.
ingress
Syntax ingress
Context config>service>vprn>if>sap
config>service>vprn>sub-if>grp-if>sap
Description This command enables the context to configure ingress SAP Quality of Service (QoS) policies and
filter policies.
If no sap-ingress QoS policy is defined, the system default sap-ingress QoS policy is used for ingress
processing. If no ingress filter is defined, no filtering is performed.
agg-rate-limit
Syntax agg-rate-limit agg-rate
no agg-rate-limit
Context config>service>vprn>if>sap>egress
config>service>vprn>sub-if>grp-if>sap>egress
Description This command defines a maximum total rate for all egress queues on a service SAP or multi-service
site. The agg-rate-limit command is mutually exclusive with the egress scheduler policy. When an
egress scheduler policy is defined, the agg-rate-limit command will fail. If the agg-rate-limit
command is specified, an attempt to bind a scheduler-policy to the SAP or multi-service site will fail.
A multi-service site must have a port scope defined that ensures all queues associated with the site are
on the same port or channel. If the scope is not set to a port, the agg-rate-limit command will fail.
Once an agg-rate-limit has been assigned to a multi-service site, the scope cannot be changed to card
level.
A port scheduler policy must be applied on the egress port or channel the SAP or multi-service site is
bound to in order for the defined agg-rate-limit to take effect. The egress port scheduler enforces the
aggregate queue rate as it distributes its bandwidth at the various port priority levels. The port
