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 7450 ESS or 7750 SR.
There are no default SAPs. All SAPs 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 is also deleted. For Internet Ethernet 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 7450 ESS or 7750 SR.
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 shut down, all SAPs on that port or channel are operationally out of service.
A SAP cannot be deleted until it has been administratively disabled (shut down).
Each SAP can be configured with only the following:
ingress or egress filter policy
ingress or egress QoS policy
accounting policy
ingress or egress scheduler policy
