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 does 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 is 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 is also deleted.
This command is also used to create a Ring APS Control SAP or a Data SAP whose traffic is protected by a Ring APS Instance.
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).The 7210 SAS supports explicit null encapsulation for VPLS service.
Specifies the physical port identifier portion of the SAP definition. See Common CLI command descriptions for command syntax.
Keyword used to create a SAP instance. The create keyword requirement can be enabled/disabled in the environment>create context.
Platforms Supported - 7210 SAS-T (access-uplink).
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 command creates a split-horizon group to ensure that Sub-Ring control messages from the major ring are only passed to the Sub-Ring control service.
Keyword to create an instance of a Ring APS Control SAP or a Data SAP whose traffic is protected by a Ring APS Instance.
Specifies the ring index of the Ethernet ring.
Specifies the name of the split horizon group to which the SAP belongs.

Supported on all 7210 SAS platforms as described in this document, including those operating in access-uplink mode
When this command is enabled, packets received on a SAP or a spoke-SDP with an unknown source MAC address is dropped only if the maximum number of MAC addresses for that SAP or spoke-SDP (see max-nbr-mac-addr) has been reached. If max-nbr-mac-addr has not been set for the SAP or spoke-SDP, enabling discard-unknown-source has no effect.
When disabled, the packets are forwarded based on the destination MAC addresses.
The no form of this command causes packets with an unknown source MAC address to be forwarded by destination MAC addresses in VPLS.
