| coCdlIntfEntry |
.1.3.6.1.4.1.9.10.88.1.1.1.1 |
|
An entry in the CDL Interface Table, providing objects to
configure and monitor CDL on an Ethernet interface.
An entry exists for each CDL capable Ethernet interface.
|
| coCdlDefectIndNotifyEnable |
.1.3.6.1.4.1.9.10.88.1.1.2 |
|
This object indicates whether a change in the received CDL
Defect Indications, including the implicit end-to-end path
defect indication as well as the CDL defect indication bits in
the CDL OAM field, causes a notification to be generated.
disabled: Received CDL aggregate defect indication bit changes
do not cause coCdlRxAggDefectIndChange notifications to be
generated, and CDL flow defect indication changes from the
CDL network at path terminating interfaces do not cause
coCdlFromCdlNetFlowDIChange notifications to be generated.
enabledAtTerminatingInterfaces: A coCdlRxAggDefectIndChange
notification is generated whenever
- the received hop-by-hop forward defect indication (FDI-H)
or the received hop-by-hop backward defect indication bit
(BDI-H) changes at a hop terminating interface, or
- the received end-to-end (aggregate path) defect
indication bit (FDI-E) changes at an aggregate path
terminating interface.
A coCdlFromCdlNetFlowDIChange notification is generated
whenever a CDL flow defect indication, i.e. implicit
end-to-end path forward defect indication or end-to-end
path backward defect indication bit, from the CDL network
changes at a path terminating interface.
enabledAtAllInterfaces: a coCdlRxAggDefectIndChange
notification is generated whenever a received CDL aggregate
defect indication bit changes on any interface, and a
coCdlFromCdlNetFlowDIChange notification is generated
whenever a CDL flow defect indication, i.e. implicit
end-to-end path forward defect indication or end-to-end
path backward defect indication bit, from the CDL network
changes at a path terminating interface.
To minimize the probability of prematurely reacting to
momentary signal variations, a soak time may be incorporated
into the notification in the following manner. A notification
is generated after a defect is first detected, when the defect
persists for a period of time that exceeds the set soak
interval specified by coCdlDefectIndSetSoakInterval. A
notification is generated after a defect stops being detected,
when the defect does not appear over a period of time that
exceeds the clear soak interval specified by
coCdlDefectIndClearSoakInterval.
When changes in CDL defect indications are received for
multiple interfaces within a short time span, notifications
should be deferred so that each notification is generated at
least one coCdlDINotifyThrottleInterval after the previous
notification.
|
| coCdlDefectIndSetSoakInterval |
.1.3.6.1.4.1.9.10.88.1.1.3 |
|
To minimize the probability of prematurely reacting to
momentary signal variations, a soak time may be incorporated
into the defect indications. The indication is set when the
defect persists for a period of time that exceeds the set soak
interval.
|
| coCdlDefectIndClearSoakInterval |
.1.3.6.1.4.1.9.10.88.1.1.4 |
|
To minimize the probability of prematurely reacting to
momentary signal variations, a soak time may be incorporated
into the defect indications. The indication is cleared when no
defect occurs over a period of time that exceeds the clear soak
interval.
|
| coCdlDINotifyThrottleInterval |
.1.3.6.1.4.1.9.10.88.1.1.5 |
|
The minimum time interval between generation of successive
CDL defect indication 'notification-events' by this agent. A
'notification-event' is the transmission of a single trap or
inform PDU to a list of notification destinations.
If more than one change occurs within a short time span, for
for example if hop-by-hop forward defect indications are
received for multiple interfaces, then notification-events
for these changes should be deferred by the agent so that each
notification-event occurs at least one throttle interval after
the previous notification-event. At the end of each throttle
interval, one notification-event should be generated if the
current defect indication state on any interface is different
from the last state indicated in a notification-event. In such
a case, another throttle interval is started immediately.
|
| coCdlFlowTermEntry |
.1.3.6.1.4.1.9.10.88.1.2.1.1 |
|
An entry that contains objects used to manage a logical or
physical interface representing a single elementary packet
stream at the point where the CDL path defect indications are
terminated. Typically, this is a point where the CDL Ethernet
encapsulation is applied and removed. This can also be a point
between a part of the CDL network that supports
packet-by-packet multiplexing, and a part of the CDL network
that does not support packet-by-packet multiplexing.
This interface may have ifType value other than
'ethernetCsmacd', if traffic from a non-Ethernet protocol is
received on this interface and then encapsulated (or otherwise
interworked) in Ethernet and then CDL, before being progressed
into the CDL network.
|
| coCdlAdminStatus |
.1.3.6.1.4.1.9.10.88.1.1.1.1.1 |
|
Enables/disables CDL on this interface.
When this object is set to 'true', CDL is enabled on
this interface. When this object is set to 'false',
CDL is disabled on this interface.
When CDL is enabled, the following actions are taken:
1) When a non-CDL packet is progressed to this interface for
transmission, the Ethernet packet is modified to carry the
CDL header. Similarly, when a received packet is progressed
from this interface to a non-CDL interface, the CDL header
is removed from the Ethernet packet.
2) Processing of CDL defect indications is activated.
3) The CDL Message Channel used to carry control (e.g. routing,
signalling) and management traffic is activated. The SNMP
agent creates an interface that represents the CDL Message
Channel. The interface representing the CDL Message Channel
is shown as a higher layer interface, with ifType
'propPointToPointSerial', residing above this CDL enabled
interface in the ifStackTable in the IF-MIB.
4) The CDL APS Channel is activated, if supported and APS is
configured for this interface.
5) Transport of multiple data flows (i.e. packet-by-packet
multiplexing) is activated, if this capability is supported
on this interface.
When CDL is disabled, only traditional (non-CDL) Ethernet
packets are transported, all packets on this interface are
treated as one Ethernet data flow, and the interface
representing the CDL message channel is deleted.
|
| coCdlForceEndOfHop |
.1.3.6.1.4.1.9.10.88.1.1.1.1.2 |
|
When set to 'true', this object forces CDL Hop Terminating
behavior at this interface. A CDL Hop Terminating Network
Element terminates (generates in one direction and consumes in
another direction) hop-by-hop CDL Defect Indications at an
interface.
When this object is set to 'false', this network element may
still act as a CDL Hop Terminating Network Element at this
interface, if either
1) Automatic Protection Switching (APS) has been configured for
this interface, or
2) this network element is an Aggregate Path Terminating
Network Element at this interface.
It is recommended to force CDL Hop Terminating behavior at
administrative boundaries. This ensures that the hop-by-hop
CDL Defect Indications (FDI-H and BDI-H) between two
administrative domains reflect only errors that occur between
the domains, even if APS is not configured for this interface.
|
| coCdlNodeBehavior |
.1.3.6.1.4.1.9.10.88.1.1.1.1.3 |
|
This object indicates the current CDL defect indication
behavior of this network element, at this interface. A network
element can take on one of three roles at a CDL enabled
interface: Aggregate Path Terminating Network Element
(endOfAggPath), Hop Terminating Network Element (endOfHop), or
CDL Regenerator.
