When configuring a SAP, consider the following:
A SAP is a local entity and only locally unique to a specific device. The same SAP ID value can be used on another Nokia router.
There are no default SAPs. All SAPs in subscriber services must be created.
The default administrative state for a SAP at creation time is administratively enabled.
When a SAP is deleted, all configuration parameters for the SAP are also deleted. For Internet Enhanced Service (IES), the IP interface must be shut down before the SAP on that interface may be removed.
A SAP is owned by and associated with the service in which it is created in each router.
A port or channel with a dot1q or BCP-dot1q encapsulation type means the traffic for the SAP is identified based on a specific IEEE 802.1Q VLAN ID value. The VLAN ID is stripped off at SAP ingress and the appropriate VLAN ID placed on at SAP egress. As a result, VLAN IDs only have local significance, so the VLAN IDs for the SAPs for a service need not be the same at each SAP.
If a port or channel is administratively shutdown, all SAPs on that port or channel are operationally out of service.
A SAP cannot be deleted until it has been administratively disabled (shutdown).
Each SAP can have one each of the following policies assigned:
Ingress filter policy
Egress filter policy
Ingress QoS policy
Egress QoS policy
Accounting policy
Ingress scheduler policy
Egress scheduler policy
