Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.868.2.5.3.1.2.4.1.4
snmpwalk -v2c -c public <target> TN-MGMT-MIB::tnIfSecondaryPort

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.868.2.5.3.1.2.4.1.4.1
snmpget -v2c -c public <target> TN-MGMT-MIB::tnIfSecondaryPort.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.868.2.5.3.1.2.4.1.4.1 s <value>
