CISCO-NETSYNC-MIB
AI MIB Summary
The CISCO-NETSYNC-MIB monitors Synchronous Ethernet (SyncE) clock selection and synchronization status on Cisco network equipment, specifically tracking ESMC (Ethernet Synchronization Messaging Channel) parameters, Quality Level (QL) values, and Synchronization Status Messages (SSM) to enforce ITU-T G.781 compliance and prevent timing loops. This module provides visibility into frequency traceability and clock source health across the Ethernet PHY layer, enabling the management of Ethernet Equipment Clocks (EEC) and Stand Alone Synchronization Equipment (SASE) states.
The Synchronous Ethernet (SyncE) MIB is defined for monitoring network synchronization based on ITU-T G.781 clock selection.
Synchronous Ethernet (SyncE) is a standard defined for delivering timing to the remote NEs through a Packet Network. SyncE is well defined by ITU-T which included G.8261, G.8262, G.8264 and G.781. It leverages the PHY layer of Ethernet to transmit frequency to the remote sites. Its functionality and accuracy mimics that of the SONET/SDH network because of its physical layer characteristic. In order to allow best clock source traceabiliy, correctly define the timing source and helps preventing timing loop, Synchronization Status Message is required for SyncE. This is similar to SONET/SDH. However, since SONET/SDH use 4 bits from the two S bytes in the SONET/SDH overhead frame for such message, Ethernet relies on a different channel called ESMC (Ethernet Synchronization Messaging Channel) which is based on IEEE 802.3 Organization Specific Slow Protocol.

ciscoNetsyncMIBThe Synchronous Ethernet (SyncE) MIB is defined
for monitoring network synchronization based on
ITU-T G.781 clock selection.
Synchronous Ethernet (SyncE) is a standard defined
for delivering timing to the remote NEs through a

which included G.8261, G.8262, G.8264 and G.781.
It leverages the PHY layer of Ethernet to transmit

and accuracy mimics that of the SONET/SDH network
because of its physical layer characteristic.
In order to allow best clock source traceabiliy,
correctly define the timing source and helps
preventing timing loop, Synchronization Status
Message is required for SyncE. This is similar

command has been applied on a T4 clock source.
The 'true' value means the clock source is not
considered by the selection process.ro TruthValue (SNMPv2-TC) .1.3.6.1.4.1.9.9.761.1.1.5.1.14 |
cnsT4ClkSrcSignalFailureThis object indicates whether or not a
signal failure event is currently being
reported on the T4 input clock source.ro TruthValue (SNMPv2-TC) .1.3.6.1.4.1.9.9.761.1.1.5.1.15 |
cnsT4ClkSrcAlarmThis object indicates whether or not an
alarm event is currently being reported
on the T4 input clock source.ro TruthValue (SNMPv2-TC) .1.3.6.1.4.1.9.9.761.1.1.5.1.16 |
cnsT4ClkSrcAlarmInfoThis object indicates the alarm reasons of

cnsT4ClkSrcFSWThis object indicates the forced switching flag.
Forced switching, as described in G.781, is used to
override the currently selected synchronization source.
The 'true' value indicates the currently selected
T4 clock source is a result of the forced switching.
The 'false' value indicates the currently selected
T4 clock source is not a result of forced switching.ro TruthValue (SNMPv2-TC) .1.3.6.1.4.1.9.9.761.1.1.5.1.18 |
cnsT4ClkSrcMSWThis object indicates the manual switching flag.
The 'true' value indicates the currently selected
T4 clock source is a result of the manual switching.
The switch allows a user to select a
synchronization source assuming it is enabled,
not locked out, not in signal fail condition,
and has a QL better than DNU in QL-enabled mode.
A clock source is enabled when it occupies a row in
cnsT4ClockSourceTable. A clock source is not locked
out when cnsT4ClkSrcLockout contains the value 'false'.
A clock source is not in signal failure condition when
cnsT4ClkSrcSignalFailure contains the value 'false'.
The QL is identified in cnsT4ClkSrcQualityLevel.
In QL-enabled mode, a manual switch
can be performed only to a source which has the
highest available QL.ro TruthValue (SNMPv2-TC) .1.3.6.1.4.1.9.9.761.1.1.5.1.19 |

cnsInpSrcFailClearThis object indicates the clear status of a signal failure
event. A value of 'true' means a signal failure event reported
on a clock source has been cleared. A value of 'false' means
