Specifications

SPECTRUM Enterprise Manager 44 SmartSwitch6000
VPI (Virtual Path Identifier)
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)
Displays the VCI value of the VCL. The maximum
VCI value cannot exceed the value allowable by
the Interface MaxVCI Bits.
Admin Status
Implemented only for a VCL that terminates a
VCC (i.e., one that is not cross-connected to other
VCLs). Its value (Up or Down) specifies the desired
administrative state of the VCL, i.e., whether
traffic flow is enabled and disabled for this VCL.
Oper Status
Indicates the current operational status of the
VCL. Up and Down indicate that the VCL is
operational or not operational, respectively.
Unknown indicates that the status of this VCL
cannot be determined.
Row Status
Used to create, delete or modify a row in this
table. To create a new VCL, this field is initially
set to createAndWait or createAndGo. This field
must not be set to active unless the following
columnar fields 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
Only exists when the local VCL endpoint is also
the VCC endpoint, and AAL5 is in use. The field
indicates the type of data encapsulation used over
the AAL5 SSCS layer. (Reference RFC 1483
Multiprotocol Encapsulation over ATM AAL5 and
the ATM Forum LAN Emulation specification.)
AAL (ATM Adaptation Layer) Type
Only exists when the local VCL endpoint is also
the VCC endpoint, and AAL is in use. The field
indicates the type of AAL used on this VCC, which
includes AAL1, AAL3/4, and AAL5. The value
Other is a user-defined AAL type. Unknown
indicates that the AAL type cannot be determined.
Last Change
The value of sysUpTime 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 field contains
a zero value.
