What is nodeDiagFatalSource?

This identifies which subsystem reported the switch's most recent fatal error, the higher-severity counterpart to nodeDiagNonFatalSource, which typically corresponds to whatever forced the reboot counted in nodeDiagFatalReboots. If nodeDiagFatalSource repeatedly reports frame-heap(4) across successive fatal events, that points to a recurring memory corruption bug rather than a one-off hardware glitch.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.3.42
snmpwalk -v2c -c public <target> CASCADE-MIB::nodeDiagFatalSource

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.3.42.1
snmpget -v2c -c public <target> CASCADE-MIB::nodeDiagFatalSource.1
