cfSubnetMask2

Module: NAT

Node type: OBJECT-TYPE

Type: IpAddress

What is cfSubnetMask2?

No DESCRIPTION exists in the source, so this reading is inferred from the IpAddress syntax and its pairing with cfIPAddr2. It holds the subnet mask that applies to the device's secondary IP address, cfIPAddr2. An admin sets it whenever the secondary interface's addressing changes.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.86.2.1.12
snmpwalk -v2c -c public <target> NAT::cfSubnetMask2

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.86.2.1.12.1
snmpget -v2c -c public <target> NAT::cfSubnetMask2.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.86.2.1.12.1 a <value>
