What is irIfIpSubnetMask?
This object stores the subnet mask assigned to a network interface. It defines the network boundary for IP routing and ARP resolution, allowing operators to understand the Layer 3 address space associated with each physical or logical interface on the device.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.33.100.1.7.1.1.3 snmpwalk -v2c -c public <target> MRV-IR-SYSTEM-MIB::irIfIpSubnetMask
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.33.100.1.7.1.1.3.1 snmpget -v2c -c public <target> MRV-IR-SYSTEM-MIB::irIfIpSubnetMask.1
