IES Service Configuration Commands
IES SAP Commands
sap
Syntax sap sap-id [create]
no sap sap-id
Context config>service>ies>interface
config>service>ies>sub-if>grp-if
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 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.
Note that you can configure an IES interface as a loopback interface by issuing the loopback
command instead of the sap sap-id command. The loopback flag cannot be set on an interface where
a SAP is already defined and a SAP cannot be defined on a loopback interface.
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. For Internet Ethernet Service (IES), the IP
interface must be shutdown before the SAP on that interface may be removed.
Default
No SAPs are defined.
Special Cases IES — An IES SAP can be defined with Ethernet ports, SONET/SDH or TDM channels. A SAP is
defined within the context of an IP routed interface. Each IP interface is limited to a single SAP
definition. Group interfaces allow more than one SAP. Attempts to create a second SAP on an IP
interface will fail and generate an error; the original SAP will not be affected.
Parameters
sap-id — Specifies the physical port identifier portion of the SAP definition.
