Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.64.1.3
snmpwalk -v2c -c public <target> MCAST-VLAN-MIB::swISMVlanForwardUnmatchedState

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.64.1.3.1
snmpget -v2c -c public <target> MCAST-VLAN-MIB::swISMVlanForwardUnmatchedState.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.171.12.64.1.3.1 i <value>
