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 use. The other may be a user-defined
AAL type. The Unknown type indicates that the AAL type cannot be
determined.
Last Change
The value of MIB II’s sysUpTime object at the time this VCL entered its
current operational state. If the current state was entered prior to the last re-
initialization of the agent, then this object contains a zero value.
