REVISION "200904210000Z" -- 21 April 2009 00:00:00 GMT
DESCRIPTION
"Original Version"
::= { mib-2 188 }
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."
SYNTAX Unsigned32 (1..4294967295)
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."
SYNTAX Unsigned32 (0..4294967295)
PwOperStatusTC ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"Indicates the operational status of the PW.
- up(1): Ready to pass packets.
- down(2): PW signaling is not yet finished, or
indications available at the service
level indicate that the PW is not
passing packets.
- 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."
SYNTAX INTEGER {
up(1),
down(2),
testing(3),
dormant(4),
notPresent(5),
lowerLayerDown(6)
}
PwAttachmentIdentifierType ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"An octet string used in the generalized Forward Error
Correction (FEC) element for identifying attachment forwarder
and groups. A NULL identifier is of zero length.
"
SYNTAX OCTET STRING (SIZE (0..255))
PwGenIdType ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"Represents the Attachment Group Identifier (AGI) Type and
Attachment Individual Identifier (AII) Type in generalized FEC
signaling and configuration.
"
SYNTAX Unsigned32( 0..254 )
PwCwStatusTC ::= TEXTUAL-CONVENTION
STATUS current
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.
"

PwStatus ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"Indicates the status of the PW and the interfaces affecting
this PW. If none of the bits are set, it indicates no faults
are reported.

pwNotForwarding(0),

psnPwTxFault(4)

PwFragSize ::= TEXTUAL-CONVENTION
DISPLAY-HINT "d"
STATUS current
DESCRIPTION
"If set to a value other than zero, it indicates the desired
fragmentation length in bytes. If set to zero,
fragmentation is not desired for PSN bound packets.
"
SYNTAX Unsigned32
PwFragStatus ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"Indicates the status of the fragmentation/reassembly process
based on local configuration and peer capability.
noFrag(0) bit indicates that local configuration is for no
fragmentation.
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
PW."

DESCRIPTION
"Index in any of the relevant configuration tables for
supplement information regarding configuration of the
specific technology. Value zero implies no additional
configuration information is applicable."
