Interface
This field displays the interface index for this VPI
and VCI.
VPI (Virtual Path Identifier)
This field displays the VPI value of the VCL. The
maximum VPI value cannot exceed the value
allowable by the Interface MaxVPI Bits.
VCI (Virtual Channel Identifier)
This field displays the VCI value of the VCL. The
maximum VCI value cannot exceed the value
allowable by the Interface MaxVCI Bits.
Admin Status
This object is implemented only for a VCL that
terminates a VCC (i.e., one that is NOT cross-
connected to other VCLs). Its value specifies the
desired administrative state of the VCL. The Up
state indicates that the traffic flow is enabled for
this VCL. The Down state indicates that the traffic
flow is disabled for this VCL.
Oper Status
This object indicates the current operational
status of the VCL. The Up and Down states
indicate that the VCL is currently operational or
not operational, respectively. The Unknown state
indicates that the status of this VCL cannot be
determined.
Row Status
This object is used to create, delete, or modify a
row in this table. To create a new VCL, this object
is initially set to “createAndWait” or
“createAndGo.” This object must not be set to
“active” unless the following columnar objects
exist in this row:
• RTD Index
• XTD Index
• AAL Type (if the local VCL endpoint is also the
VCC endpoint)
• Transmit Size (for AAL5 connections only)
• Receive Size (for AAL5 connections only)
• Encaps Type (for AAL5 connections only)
Encaps Type
This is the type of data encapsulation used over
the AAL5 SSCS layer. An instance of this object
only exists when the local VCL endpoint is also
the VCC endpoint, and AAL5 is in use. The
definitions reference RFC 1483 Multiprotocol
Encapsulation over ATM AAL5 and to the ATM
Forum LAN Emulation specification.
AAL (ATM Adaptation Layer) Type
This is the type of AAL used on this VCC, which
includes AAL1, AAL3/4, and AAL5. An instance of
this object only exists when the local VCL
endpoint is also the VCC endpoint, and AAL is in
