Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4515.1.3.1.2
snmpwalk -v2c -c public <target> SL-MAIN-MIB::slmSysSubnetMask

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4515.1.3.1.2.1
snmpget -v2c -c public <target> SL-MAIN-MIB::slmSysSubnetMask.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.4515.1.3.1.2.1 a <value>
