Description This command creates a Service Access Point (SAP) within a service. A SAP is a combination of port
and encapsulation parameters which identifies the service access point on the interface and within the
7210 SAS. Each SAP must be unique.
A physical port can have only one SAP to be part of one service. Multiple SAPS can be defined over
a physical port but each of these SAPs should belong to a different service.
All SAPs must be explicitly created. If no SAPs are created within a service or on an IP interface, a
SAP will not exist on that object.
Enter an existing SAP without the create keyword to edit SAP parameters. The SAP is owned by the
service in which it was created.
A SAP can only be associated with a single service. A SAP can only be defined on a port that has
been configured as an access port using the config interface port-type port-id mode access
command.
If a port is shutdown, all SAPs on that port become operationally down. When a service is shutdown,
SAPs for the service are not displayed as operationally down although all traffic traversing the service
will be discarded. The operational state of a SAP is relative to the operational state of the port on
which the SAP is defined.
The no form of this command deletes the SAP with the specified port. When a SAP is deleted, all
configuration parameters for the SAP will also be deleted.
No SAPs are defined.
Special Cases A default SAP has the following format: port-id:*. This type of SAP is supported only on Ethernet
MDAs and its creation is allowed only in the scope of Layer 2 services (Epipe and VPLS).
Parameters sap-id — Specifies the physical port identifier portion of the SAP definition. See Common CLI
Command Descriptions on page 925 for command syntax.
with-aggregate-meter — This parameter is supported only for 7210 SAS-X for releases prior to
R3.0r1. This parameter is specified during SAP creation if the aggregate-meter-command is used
for the SAP. A limited set of hardware resources are available for SAPs that intend to use the
aggregate meters.
create — Keyword used to create a SAP instance. The create keyword requirement can be enabled/
disabled in the environment>create context.
g8032-shg-enable — This command must only be used with the SAPs created in the service for the
virtual channel on the interconnection nodes in a topology that uses multiple rings. This
