Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.791.2.9.2.2.2.8.7
snmpwalk -v2c -c public <target> CA-NTOS-MIB::ntDefMemPhysCritical

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.791.2.9.2.2.2.8.7.1
snmpget -v2c -c public <target> CA-NTOS-MIB::ntDefMemPhysCritical.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.791.2.9.2.2.2.8.7.1 i <value>
