Configuring a VPRN Interface SAP
VPRN Interface SAP
VPRN interfac e
A SAP is a combination of a port and encapsulation parameters which identifies the service access
point on the interface and within the SR. Each SAP must be unique within a router. A SAP cannot
be defined if the interface
loopback command is enabled.
When configuring VPRN interface SAP parameters, a default QoS policy is applied to each
ingress and egress SAP. Additional QoS policies and scheduler policies must be configured in the
config>qos context. Filter policies are configured in the config>filter context and must be
explicitly applied to a SAP. There are no default filter policies.
VPRN interface ATM SAP parameters can only be configured on ATM-type MDAs and ATM-
configured ports. The
periodic-loopback command can only be enabled when the
config>system>atm>oam context is enabled. See the 7750 SR OS Basic System Configuration
Guide.
Refer to OSPF Configuration Commands on page 943 for CLI commands and syntax.
The following displays the command usage to configure VPRN interface SAP parameters:
Example: config>service# vprn 1
config>service>vprn# interface "to-cel"
config>service>vprn>if# sap 1/1/10:1
config>service>vprn>if>sap# egress
config>service>vprn>if>sap>egress# filter ip 6
config>service>vprn>if>sap>egress# qos 1010
config>service>vprn>if>sap>egress# scheduler-policy SLA1
config>service>vprn>if>sap>egress# exit
config>service>vprn>if>sap# ingress
config>service>vprn>if>sap>ingress# qos 100
config>service>vprn>if>sap>ingress# scheduler-policy SLA2
config>service>vprn>if>sap>ingress# exit
