CISCO-CDL-MIB

        This MIB module defines objects to manage Converged Data Link
(CDL).
        
CDL provides OAM&P (Operation, Administration, Maintenance and
Provisioning) in Ethernet packet-based optical networks without
a SONET/SDH layer.
        
The CDL functionality can be divided into the following
categories:
        
APS/Defect Indications:
   The CDL frame carries defect indication bits and provides
   signalling mechanism support for automatic protection
   switching.
        
Message Channel:
   The message channel is used to carry control (e.g. routing,
   signalling) and management traffic.
        
Packet-by-packet multiplexing of multiple data flows:
   CDL uses one or two octets to identify the elementary 
   packet stream that this packet belongs to. This allows 
   more than one elementary packet stream to share the 
   bandwidth on a CDL enabled interface.
        
This MIB defines objects to manage Defect Indications and the
Packet-by-packet Multiplexing feature.
        
The CDL Message channel is modeled as a separate interface and
should be controlled using the IF-MIB and other MIBs for
managing IP. This MIB does not provide a mechanism to manage
the CDL message channel.
        
APS configuration and monitoring can be done using the
CISCO-APS-MIB and CISCO-APS-EXT-MIB.

Notifications / Traps (2)
NameOIDDescription
coCdlRxAggDefectIndChange
coCdlRxAggDefectIndCurrStatus coCdlRxAggDefectIndLastChange
.1.3.6.1.4.1.9.10.88.0.1
This notification is sent when the value of the hop-by-hop
forward defect indication (FDI-H), hop-by-hop backward defect
indication (BDI-H), or end-to-end (aggregate path) forward
defect indication (FDI-E) bit received on an interface changes.

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.
coCdlFromCdlNetFlowDIChange
coCdlFromCdlNetFlowDICurrStatus coCdlFromCdlNetFlowDILastChange
.1.3.6.1.4.1.9.10.88.0.2
This notification is sent when the value of the received
end-to-end path forward defect indication or the received
end-to-end path backward defect indication changes.

Note that the end-to-end path forward defect indication is
implicit, i.e. it is not signalled using a bit. An end-to-end
path forward defect is inferred when no CDL Ethernet or Idle
packets are received over a pre-determined length of time.

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.
