+

+PwGroupID ::= TEXTUAL-CONVENTION

+   DISPLAY-HINT "d"

+   STATUS      current

+   DESCRIPTION

+        "An administrative identification for grouping a

+         set of service-specific pseudowire services."

+   SYNTAX  Unsigned32

+

+PwIDType ::= TEXTUAL-CONVENTION

+   DISPLAY-HINT "d"

+   STATUS      current

+   DESCRIPTION

+        "Pseudowire Identifier.  Used to identify the PW

+         (together with some other fields) in the signaling

+         session."

+   SYNTAX  Unsigned32

+

+PwIndexType ::= TEXTUAL-CONVENTION

+   DISPLAY-HINT "d"

+   STATUS      current

+   DESCRIPTION

+        "Pseudowire Index.  A unique value, greater than zero,

+        for each locally defined PW.  Used for indexing

+        several MIB tables associated with the particular PW.

+        It is recommended that values are assigned contiguously

+        starting from 1.  The value for each PW MUST remain

+        constant at least from one re-initialization

+        to the next re-initialization."

+PwIndexOrZeroType ::= TEXTUAL-CONVENTION

+   DISPLAY-HINT "d"

+   STATUS      current

+   DESCRIPTION

+        "This TEXTUAL-CONVENTION is an extension of the

+         PwIndexType convention.  The latter defines a greater-

+         than-zero value used to identify a pseudowire

+         in the managed system.  This extension permits the

+         additional value of zero.  The zero value is object-specific

+         and MUST therefore be defined as part of the description of

+         any object that uses this syntax.  Examples of the usage of

+         zero might include situations where pseudowire was unknown,

+         or where none or all pseudowires need to be referenced."

+   DESCRIPTION

+     "Indicates the operational status of the PW.

+

+     - up(1):             Ready to pass packets.

+     - down(2):           PW signaling is not yet finished, or

+     - testing(3):        AdminStatus at the PW level is set to

+                          test.

+

+     - dormant(4):        The PW is not in a condition to pass

+                          packets but is in a 'pending' state,

+                          waiting for some external event.

+     - notPresent(5):     Some component is missing to accomplish

+                          the setup of the PW.  It can be

+                          configuration error, incomplete

+                          configuration, or a missing H/W component.

+     - lowerLayerDown(6): One or more of the lower-layer interfaces

+                          responsible for running the underlying PSN

+                          is not in OperStatus 'up' state."

+   DESCRIPTION

+      "Indicates the status of the control word (CW) negotiation

+       based on the local configuration and the indications received

+       from the peer node.

+

+       waitingForNextMsg(1) indicates that the node is waiting for

+       another label mapping from the peer.

+

+       sentWrongBitErrorCode(2) indicates that the local node has

+       notified the peer about a mismatch in the C-bit.

+

+       rxWithdrawWithWrongBitErrorCode(3) indicates that a withdraw

+       message has been received with the wrong C-bit error code.

+

+       illegalReceivedBit(4) indicates a C-bit configuration with

+       the peer that is not compatible with the PW type.

+

+       cwPresent(5) indicates that the CW is present for this PW.

+       If signaling is used, the C-bit is set and agreed upon between

+       the nodes.  For manually configured PW, the local

+       configuration requires the use of the CW.

+

+       cwNotPresent(6) indicates that the CW is not present for this

+       PW.  If signaling is used, the C-bit is reset and agreed upon

+       between the nodes.  For manually configured PW, the local

+       configuration requires that the CW not be used.

+

+       notYetKnown(7) indicates that a label mapping has not yet

+       been received from the peer.

+

+       noFrag(0) bit indicates that local configuration is for no

+

+       cfgFragGreaterThanPsnMtu(1) bit indicates that the local node

+       is set to fragment, but the fragmentation size is greater

+       than the MTU available at the PSN between the nodes.

+       Fragmentation is not done in this case.

+

+       cfgFragButRemoteIncapable(2) bit indicates that the local

+       configuration conveys the desire for fragmentation but

+       the peer is not capable of reassembly.

+

+       remoteFragCapable(3) bit indicates that the remote node

+       is capable to accept fragmented PDUs.

+

+       fragEnabled(4) bit indicates that fragmentation will be used

+       on this PW.  Fragmentation can be used if the local node was

+       configured for fragmentation, the peer has the capability

+       to accept fragmented packets, and the CW is in use for this
