6.2.1.1
“atmVclOperStatus” Object (atmVclEntry 4)
This object indicates the current operational status of the VCL. Possible values are:
up(1) VCL is currntly Operational.
down(2) VCL is currently Not Operational.
unknown (3) The
state of the VCL can’t be determined.
6.2.1.2
“atmVclLastChange” Object (atmVclEntry 5)
This object contains the value of the MIB II’s sysUpTime object at the time the 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.
6.2.1.3
“atmVccAalType” Object (atmVclEntry 8)
This object identifies the type of AAL used with the VCC. The only valid values for this
object is:
aal5(3) AAL5
unknow(5)
The unknown type indicates that the AAL type cannot be determined.
6.2.1.4
“atmVccAal5CpcsTransmitSduSize” Object (atmVclEntry 9)
This object contains the maximum AAL5 CPCS (Common Part Convergence Sublayer)
SDU size in octets that is supported on the transmit direction of this VCC. :An instance of
this object only exists when the local VCL end-point is also the VCC end-point, and AAL5
is in use
atmVccAal5CpcsTransmitSduSize =
9188
BAC supports a maximum
user data size of 9188.
6.2.1.5
“atmVclAal5CpcsReceiveSduSize” Object (atmVclEntry 10)
This object contains the maximum AAL5 CPCS (Common Part Convergence Sublayer)
SDU size in octets that is supported on the receive direction of this VCC. The possible
values are:
atmVccAal5CpcsReceiveSduSize =
9188
- BAC supports a maximum
user data size of 9188.
6.2.1.6
“atmVclEncapsType” Object (atmVclEntry 11)
This object identifies the type of data encapsulation used over the AAL5 SSCS (Service
Specific Convergence Sublayer) layer. The only valid values for this object is:
atmVclEncapsType =
llcEncapsulation(7).
6.2.2
Virtual Channel Cross Connect Group (RFC 2515)
This table contains configuration and state information of point-to-point,
point-to-multipoint or multipoint-to-multipoint VC cross-connects for PVCs. This table has
read-create access and is used to cross-connect the VCLs together in an ATM switch or
network that belong to a VC connection. The atmVcCrossConnectIndex is used to associate
the related VCLs that are cross-connected together. The model using step-wise procedures
described for setting up a VP cross-connect is also used for setting up a VC cross-connect.
The ATM Virtual Channel (VC) Cross Connect Table, atmVcCrossConnectEntry table
contains the following objects:
