What is acSysTDMClockEnableFallBack?

This OID controls how the system handles clock failures: 0 (Manual fallback), 1 (Auto non-revertive), or 2 (Auto revertive). Engineers enable automatic fallback to prevent voice quality degradation when the primary clock source fails. Setting this to 2 means the system will automatically switch to a backup clock on failure and revert to the primary clock when it recovers.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5003.9.10.10.1.2.1.2
snmpwalk -v2c -c public <target> AC-SYSTEM-MIB::acSysTDMClockEnableFallBack

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.5003.9.10.10.1.2.1.2.1
snmpget -v2c -c public <target> AC-SYSTEM-MIB::acSysTDMClockEnableFallBack.1
