What is sysInfoClockBErr?

This OID is a flag (0 or 1) indicating whether the clock on backplane B is operating correctly. Network engineers monitor this alongside ClockAErr to ensure at least one clock is always healthy in redundant configurations. A value of 0 means the clock on backplane B is working normally, so the device can continue operating synchronously.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.19.20
snmpwalk -v2c -c public <target> ACMIB::sysInfoClockBErr

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.19.20.1
snmpget -v2c -c public <target> ACMIB::sysInfoClockBErr.1
