VLL Service Configuration Commands
CES SAP Commands
sap
Syntax sap sap-id [no-endpoint] [create]
sap sap-id endpoint endpoint-name [create]
no sap sap-id
Context config>service>cpipe
This command creates a Service Access Point (SAP) within a service. A SAP is a combination of port
Description
and encapsulation parameters which identifies the service access point on the interface and within the
service router. 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 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.
No SAPs are defined.
Default
A SAP can be defined with Ethernet ports, SONET/SDH or TDM channels. At most, only one sdp-id
Special Cases
can be bound to an VLL service. Since a VLL is a point-to-point service, it can have, at most, two end
points. The two end points can be one SAP and one SDP or two SAPs. Up to 49 SDPs can be
associated with a service in a single router. Each SDP must have a unique router destination or an
error will be generated.
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. This type of SAP is mutually
exclusive with a SAP defined by explicit null encapsulation (for example, 1/1/1:0).
sap-id — Specifies the physical port identifier portion of the SAP definition.
Parameters
port-id — Specifies the physical port ID in the slot/mda/port format.

If the card in the slot has Media Dependent Adapters (MDAs) installed, the port-id must be in the
slot_number/MDA_number/port_number format. . For example 6/2/3 specifies port 3 on MDA 2
in slot 6.
