cnsT4ClkSrcSignalFailure

Module: CISCO-NETSYNC-MIB

OID (symbolic): CISCO-NETSYNC-MIB::cnsT4ClkSrcSignalFailure

OID (numeric): 1.3.6.1.4.1.9.9.761.1.1.5.1.15

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-only

Description: This object indicates whether or not a signal failure event is currently being reported on the T4 input clock source.

What is cnsT4ClkSrcSignalFailure?

This object indicates whether a signal failure is currently detected on a specific T4-table candidate source, the T4-selection analog of cnsInpSrcSignalFailure, flagging a hard problem with the physical or logical timing signal on that candidate. Seeing this flip to true right as the active T4-feeding source changes confirms this specific fault triggered a T4-side failover, distinct from anything happening on the T0 path.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.761.1.1.5.1.15
snmpwalk -v2c -c public <target> CISCO-NETSYNC-MIB::cnsT4ClkSrcSignalFailure

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.761.1.1.5.1.15.1
snmpget -v2c -c public <target> CISCO-NETSYNC-MIB::cnsT4ClkSrcSignalFailure.1
