Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.208.39.3.1 snmpwalk -v2c -c public <target> ETH-SWITCH-MIB::portLastChange
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.208.39.3.1.1 snmpget -v2c -c public <target> ETH-SWITCH-MIB::portLastChange.1
