a3ComSysIpInterfaceNetMask
Module: A3COM-SWITCHING-SYSTEMS-MIB
OID (symbolic): A3COM-SWITCHING-SYSTEMS-MIB::a3ComSysIpInterfaceNetMask
OID (numeric): 1.3.6.1.4.1.43.29.4.15.2.2.1.3
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-only
Description: The subnet mask associated with this IP interface. The value of the mask is an IP address with all the network bits set to 1 and all the host bits set to 0.
What is a3ComSysIpInterfaceNetMask?
This OID provides the subnet mask for the interface, with network bits set to 1 and host bits to 0. Engineers use it to calculate the network range and routing behavior. Example: 255.255.255.0 for a /24 network.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.43.29.4.15.2.2.1.3 snmpwalk -v2c -c public <target> A3COM-SWITCHING-SYSTEMS-MIB::a3ComSysIpInterfaceNetMask
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.43.29.4.15.2.2.1.3.1 snmpget -v2c -c public <target> A3COM-SWITCHING-SYSTEMS-MIB::a3ComSysIpInterfaceNetMask.1
