Tables in the PW-ENET-MIB
The PW-ENET-MIB consists of the following table:
•
cpwVcEnetTable (
)—Provides Ethernet port mapping and VLAN configuration for each
Ethernet emulated virtual connection. This table is indexed on cpwVcIndex, which uniquely
identifies a singular connection. The second level index for this table is cpwVcEnetPwVlan, which
indicates VLANs on this VC. This table is used only for Ethernet VC types—ethernetVLAN,
ethernet, or ethernet virtual private LAN service (VPLS), and is implemented as read-only.

cpwVcEnetTable
lists the cpwVcEnetTable objects and their descriptions.

Description
cpwVcEnetPwVlan
The VLAN value for frames on a VC. This is one of the
indexes to the table so multiple VLAN values can be
configured for a PW VC. This value is 4096 to indicate
untagged frames; that is, if the cpwVcEnetVlanMode
value is removeVlan. This value is the VLAN value of
the access circuit if the cpwVcEnetVlanMode value is
noChange. The value of 4097 is used if the object is not
applicable; for example, when mapping all packets from
an Ethernet port to the VC.

cpwVcEnetVlanMode
Indicates the way the VLAN field is handled between the
access circuit and the PW VC. The possible values for
this field are as follows:
access circuit and the PW VC. The possible values for
this field are as follows:
•
noChange—Indicates that the VC contains the
original user VLAN, as specified in
cpwVcEnetPortVlan.
original user VLAN, as specified in
cpwVcEnetPortVlan.
•
changeVlan—Indicates that the VLAN field on the
VC may be different from the VLAN field on the
user’s port.
VC may be different from the VLAN field on the
user’s port.
•
removeVlan—Indicates that the encapsulation on
the VC does not include the original VLAN field.
the VC does not include the original VLAN field.
•
addVlan—Indicates that a VLAN field is added on
the PSN bound direction (that is, on the PW).
the PSN bound direction (that is, on the PW).
cpwVcEnetPortVlan
Defines the VLAN value on the physical port (or VPLS
virtual port) if a change is required to the VLAN value
between the VC and the physical or virtual port. It is
equal to cpwVcEnetPwVlan if the cpwVcEnetVlanMode
value is noChange. A value of 4096 indicates that no
VLAN is associated with the VC; that is, assigning
Default VLAN to untagged frames. If all traffic from the
VC is being forwarded to the port, then this value is 4097
indicating it is not relevant.
