Description: The boot time of the switch is equal to subtract systemUpTime from swSNTPCurrentTime
What is swSystemBootTime?
This string reports the switch's boot time, calculated by subtracting swSystemUpTime from the current SNTP-derived time. Admins use it to know the actual wall-clock time the switch last booted, rather than just the elapsed uptime duration. Reading swSystemBootTime tells an admin exactly when, by calendar date and time, the switch last came up.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.10.10.3 snmpwalk -v2c -c public <target> TIME-MIB::swSystemBootTime
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.10.10.3.1 snmpget -v2c -c public <target> TIME-MIB::swSystemBootTime.1
