This MIB uses an ATM over pseudowire (ATMoPW) connection that consists of two segments: the
ATM segment and the pseudowire segment. The PW-ATM-MIB provides hooks to those segments.
The PW MIB contains information about the pseudowire segment, and the PW-ATM-MIB contains
information about the ATM segment called the attachment circuit.

The PW MIB contains information about the pseudowire segment, and the PW-ATM-MIB contains
information about the ATM segment called the attachment circuit.
The PW-ATM-MIB is defined at the Pseudowire Service Emulation Layer and resides on top of the
generic PW-MIB as shown in
generic PW-MIB as shown in
. Therefore, the PW-ATM-MIB is highly dependent on the
existence and the service provided by the PW-MIB. In addition, an existing PW-ATM connection
entry must associate with an existing VC entry in the PW-MIB.
entry must associate with an existing VC entry in the PW-MIB.
The PW-ATM-MIB and the generic PW-MIB are logically tied by the PW VC Index, which is an
internal index defined to support the PW-MIB. Each PW VC index uniquely maps into an existing
VC entry in the PW-MIB and the PW-ATM-MIB.

Tables in the PW-MIB
The PW-MIB consists of the following tables:
•
cpwVcTable (
)—Contains high-level generic parameters related to VC creation. This table
is implemented as read only and is indexed by the cpwVcIndex, which uniquely identifies a singular
connection. A row in this table represents an emulated virtual connection. This table is used for all
VC types.
connection. A row in this table represents an emulated virtual connection. This table is used for all
VC types.
•
cpwVcPerfTotalTable (
)—Provides per-VC performance information from the VC start time.
This table is indexed by the cpwVcIndex.
•
cpwVcIdMappingTable (
)—Provides reverse mapping of the existing VCs based on VC type
and VC ID ordering. This table is typically useful for element manager software (EMS) ordered
query of existing VCs. This table is indexed by cpwVcIdMappingVcType, cpwVcIdMappingVcID,
cpwVcIdMappingPeerAddrType, and cpwVcIdMappingPeerAddr. This table is implemented as
read only.

cpwVcIdMappingPeerAddrType, and cpwVcIdMappingPeerAddr. This table is implemented as

•
cpwVcPeerMappingTable (
)—Provides reverse mapping of the existing VCs based on VC
type and VC ID ordering. This table is typically useful for EMS ordered query of existing VCs. This
table is indexed by cpwVcPeerMappingPeerAddrType, cpwVcPeerMappingPeerAddr,
cpwVcPeerMappingVcType, and cpwVcPeerMappingVcID. This table is implemented as read only.
