Specifications

SPECTRUM Enterprise Manager 42 SmartSwitch6000
Oper Status
Indicates the current operational status of the
VCL. Up and Down indicate whether the VCL is
operational. Unknown indicates that the status of
this VCL 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.
RTD (Receive Traffic Description) Index
The value of this field identifies the row in the
ATM Traffic Descriptor Table that applies to the
receive direction of this VCL.
TTD (Transmit Traffic Description) Index
The value of this field identifies the row of the
ATM Traffic Descriptor Table that applies to the
transmit direction of this VCL.
AAL (ATM Adaptation Layer) Type
An instance of this field 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 other type is a user-defined AAL type.
The unknown type indicates that the AAL type
cannot be determined.
Transmit Size
An instance of this field only exists when the local
VCL endpoint is also the VCC endpoint and AAL5
is in use. The field indicates the maximum AAL5
CPCS SDU size in octets that is supported on the
transmit direction of this VCC.
Receive Size
This field is used when the local VCL endpoint is
also the VCC endpoint and AAL5 is used. It
indicates the maximum AAL5 CPCS SDU size in
octets that is supported on the receive direction of
this VCC.
Encaps Type
An instance of this field 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.)
VCL CC (Cross Connect) Id
This field is implemented only for a VCL that is
cross-connected to other VCLs that belong to the
same VCC. All such associated VCLs have the
same value as this field, and all their cross-
connections are identified by entries in the Cross
Connect Table for which VCL CC Id has the same
value. The value of this field is initialized after the
