pwVcCemEntryThis MIB reports to the PW-MIB. This table is indexed by
the same index that was created for the associated entry
in the PW VC Table (in the PW-MIB).
- The PwVcIndex.
- The PwVcInstance.
An entry is created in this table by the agent for every
entry in the pwVc table with a VcType of 'cem'.
This table provides per CEM VC performance information.
HC (high capacity) counters are required for some counts
due to the high speeds expected with CEM services. A SONET
path of width 48 (STS-48c) can rollover non-HC counters in
a few minutes.
CEM bridges the SONET and packet worlds. In the packet
world, counts typically start from the time of service
creation - and don't stop. In the SONET world, counts are
kept in 15 minute intervals. The CEM-MIB supports both
methods. Thestats in the VC CEM table count forever. The
15 minute interval counts are in the tables following this.
NOTE: Outbound errors are currently not considered in the
CEM-MIB. It is assumed that CEM packets are forwarded as
they are generated. i.e., It is assumed that there are no
congestion issues at the point of CEM adaptation. PwVcCemEntry .1.3.6.1.3.8888.1.1.1 |
pwVcCemSonetPathIfIndexThis is a unique index within the ifTable. It represents
the interface index for the SONET path. A value of zero
indicates an interface index that has yet to be configured
or has since disappeared.
Note: if there are multiple instances of CEM VC, then the
pathIfIndex object MUST be identical in each instance.rw InterfaceIndexOrZero (IF-MIB) .1.3.6.1.3.8888.1.1.1.1 |

entering failure state is implementation specific.
Note: definition of 'CEM failure' is for further
study. One possible definition: in LOPS state for 2.5
seconds. A 'CEM failure' may be also be determined (via
software) as a result of trend analysis (e.g., missing
packet ratio over time).ro Bits .1.3.6.1.3.8888.1.1.1.25 |
pwVcCemPerfLastFailureTimeStampThe value of sysUpTime on the most recent occasion at

pwVcCemPerfDiscontinuityTimeThe value of sysUpTime on the most recent occasion at
which any one or more of this segment's Counter32 or
Counter64 suffered a discontinuity. If no such
discontinuities have occurred since the last re-
initialization of the local management subsystem, then
this object contains a zero value.ro TimeStamp (SNMPv2-TC) .1.3.6.1.3.8888.1.1.1.27 |
pwVcCemConfIndexNextThis object contains an appropriate value to be used
for pwVcCemConfIndex when creating entries in the
pwVcCemConfTable. The value 0 indicates that no
unassigned entries are available. To obtain the
value of pwVcCemConfIndex for a new entry in the
pwVcCemConfTable, the manager issues a management
protocol retrieval operation to obtain the current
value of pwVcCemConfIndex. After each retrieval
operation, the agent should modify the value to
reflect the next unassigned index. After a manager
retrieves a value the agent will determine through
its local policy when this index value will be made
available for reuse.ro PwVcCemConfIndex .1.3.6.1.3.8888.1.2 |

pwVcCemConfigErrorVarious configurations errors. Illegal settings within
the pwVcCemConf table.ro Bits .1.3.6.1.3.8888.1.3.1.2 |
pwVcCemConfMaxPktLengthThis is the maximum CEM packet length in number
of bytes (including CEM header and payload). It is
fixed and applies to inbound and outbound packets
carrying user payload. Although there is no control
over inbound packets, those of illegal length are
discarded and accounted for (see
pwVcCemPerfPktsBadLength.)
Note: DBA packets have their own (shorter) length
and are not effected by this setting. If there were
to be CEM payload compression, compressed packets
would have their own (shorter) length not effected
by this setting.
Used by signaling (LDP) to fill in the 'Virtual Circuit
FEC element' and the CEM interface parameters therein.rw Unsigned32 .1.3.6.1.3.8888.1.3.1.3 |
pwVcCemConfMinPktLengthThis is the minimum CEM packet length in number of
bytes (including CEM header and payload). It applies
to CEM's bandwidth-savings packets. Currently DBA is
the only bandwidth-savings packet type (in the future,
CEM may support compression). Minimum packet length is
necessary in some systems or networks.
Setting Zero here indicates that there is no minimum
packet restriction. If non-zero, then packets too
small are be discarded and accounted for (see
pwVcCemPerfPktsBadLength.)
Used by signaling (LDP) to fill in the 'Virtual Circuit
FEC element' and the CEM interface parameters therein.rw Unsigned32 .1.3.6.1.3.8888.1.3.1.4 |
pwVcCemConfCemOptionsUsed by signaling (LDP) to fill in the 'Virtual Circuit FEC
element' and the CEM interface parameters therein. CEM
options
are formatted into bit fields within a 16-bit word. Such
fields will define CEM-DBA, STS-n starting time slot, etc.rw Unsigned32 .1.3.6.1.3.8888.1.3.1.5 |
pwVcCemConfPktResequenceIf set True: as inbound packets are queued in the jitter
buffer, out of order packets are re-sequenced. The
maximum sequence number differential (i.e., the range in
which resequencing can occur) is dependant on the depth of
the jitter buffer. See pwVcCemConfJtrBfrDepth.
NOTE: Some implementations may not support this feature.

If set True, then error code is set in pwVcCemConfigError.
NOTE: Some implementations may always have this feature on.
If set False, then error code is set in pwVcCemConfigError.rw TruthValue (SNMPv2-TC) .1.3.6.1.3.8888.1.3.1.6 |
pwVcCemConfEnableDBAAny bits set here MUST enable the DBA (dynamic bandwidth
allocation) feature for the specified condition. Setting
allOnesOnAis will cause CEM packet payload suppression
when AIS is detected on the associated SONET path.
Similarly, allZerosOnUnequipped will cause payload
suppression when the SONET path is un-equipped. During
these conditions, CEM packets will continue to be sent,
but with indicators set in the CEM header instructing the
remote to play all ones or zeros onto its SONET path.
NOTE: some implementations may not support this feature.
If set, then an error code is set in pwVcCemConfigError.rw Bits .1.3.6.1.3.8888.1.3.1.7 |
pwVcCemConfJtrBfrDepthThis setting configures the number of packet buffers
reserved for this CEM VC. This object essentially sets
the maximum amount of time allowed between CEM packets
before the jitter buffer empties. This variable should
be set based on the SONET path width (speed) and the
amount of delay variation expected to be introduced by
the network. Like bandwidth, jitter buffers are likely
to be a limited resource to be managed.rw Unsigned32 .1.3.6.1.3.8888.1.3.1.8 |

pwVcCemConfErrorActionThese are the actions to take when inbound packets are
missing due to gap in sequence numbers (uncorrectable via
available re-sequencing), jitter buffer underruns, or
packets with bad CEM headers. These patterns are sent
(played) on the SONET path. These settings are used for
immediate errors and (unless the pwVcCemConfUasAction is
'errorAction') are not in effect once the CEM VC is in
UAS state. For userValue see pwVcCemConfUserErrorAction.rw Enumeration .1.3.6.1.3.8888.1.3.1.11 |

pwVcCemConfSesToUasNumber of consecutive SESs before declaring VC in UAS
state (and at which point pwVcCemPerfUASs starts counting).
The SesToUas default value is 10 seconds.
NOTE: 10 consecutive non-SESs cause the VC to exit the
UAS state. See pwVcCemPerfSESs and pwVcCemPerfUASs.rw Unsigned32 UNITS "seconds" .1.3.6.1.3.8888.1.3.1.13 |
pwVcCemConfUasActionThese are the actions to take once the CEM VC has been
declared in UAS state (as observed in pwVcCemPerfDefects)
and there are missing packets (as described in the
pwVcCemConfErrorAction object, above).
These patterns are sent (played) on the SONET path. If
'errorAction' is selected, then the pwVcCemConfErrorAction
settings stay in effect even after the CEM VC is in UAS.

pwVcCemSonetPathExtTableThis table associates a SONET path with a CEM VC (or
a set of CEM VCs) and provides the starting time-slot
of the SONET path. It as assumed that the transmit
and receive sides of the SONET path have the same
starting time-slots. It is also assumed that STSn
paths have contiguous time-slots. SEQUENCE OF PwVcCemSonetPathExtEntry .1.3.6.1.3.8888.1.6 |
pwVcCemSonetPathExtEntryThis table is indexed by the SONET path ifIndex. An
entry to this table is created by the agent when an
entry (intended for CEM) is created in the
sonetPathCurrentTable. Alternatively, an agent may
create an entru in this table at the point where a
valid ifIndex is written to pwVcCemSonetPathIfIndex
in the pwVcCem table. The pwVcCemSonetPathExt table
binds a SONET path to a PW CEM VC. A VC index of 0
indicates that the binding has not yet been set. PwVcCemSonetPathExtEntry .1.3.6.1.3.8888.1.6.1 |

pwVcCemSonetPathExtTimeSlotStarting time-slot for this SONET path within the
SONET line and section. For OC-48, this value could
range from 1 to 48. The SONET path width must be taken
into consideration here, for example, in an OC-48 an
STS-3c could not start at time-slot 47.rw Unsigned32 .1.3.6.1.3.8888.1.6.1.3 |
