Syntax sap sap-id [create]
no sap sap-id
Context config>service>vprn>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
7210 SAS. 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.
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.
Default No SAPs are defined.
Special Cases VPRN — A VPRN SAP must be defined on an Ethernet interface.
Parameters sap-id — Specifies the physical port identifier portion of the SAP definition. See Common CLI
Command Descriptions on page 925 for command syntax.
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 2/3 specifies port 3 on MDA 2 in
slot .
The port-id must reference a valid port type. When the port-id parameter represents SONET/
SDH and TDM channels the port ID must include the channel ID. A period “.” separates the
physical port from the channel-id. The port must be configured as an access port.
If the SONET/SDH port is configured as clear-channel then only the port is specified.
create — Keyword used to create a SAP instance.
split-horizon-group group-name — Specifies the name of the split horizon group to which the SAP
belongs.
