What is protocolDirLastChange?
This timestamp marks when the protocol directory table was last changed, in hundredths of a second since device boot. Operators use it to verify that protocol monitoring configurations remain stable across polling intervals. If this value keeps changing unexpectedly, it signals unintended modifications to what protocols are being tracked.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.16.11.1 snmpwalk -v2c -c public <target> RMON2-MIB::protocolDirLastChange
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.16.11.1.1 snmpget -v2c -c public <target> RMON2-MIB::protocolDirLastChange.1
