snmpwalk -v2c -c public <target> IB-SM-MIB::ibSmPortInfoLinkDownDefState

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.3.117.7.1.3.1.1.17.1
snmpget -v2c -c public <target> IB-SM-MIB::ibSmPortInfoLinkDownDefState.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.3.117.7.1.3.1.1.17.1 i <value>
