Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.818.1.1.1.8
snmpwalk -v2c -c public <target> CISCO-NAT-CGN-EXT-MIB::cNatCgnInstanceProtocolPortBulkAllocControl

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.818.1.1.1.8.1
snmpget -v2c -c public <target> CISCO-NAT-CGN-EXT-MIB::cNatCgnInstanceProtocolPortBulkAllocControl.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.9.9.818.1.1.1.8.1 i <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> cNatCgnInstanceProtocolPortBulkAllocControl.1
