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
7750. Each SAP must be unique.
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 router interface port-type port-id mode access
command. Channelized TDM ports are always access ports.
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 following are supported:
