Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.17.2.6
snmpwalk -v2c -c public <target> BRIDGE-MIB::dot1dStpRootCost

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.17.2.6.1
snmpget -v2c -c public <target> BRIDGE-MIB::dot1dStpRootCost.1
