tnIPv4SubnetMask
Module: TN-DEV-SYS-IPMGMT-MIB
OID (symbolic): TN-DEV-SYS-IPMGMT-MIB::tnIPv4SubnetMask
OID (numeric): 1.3.6.1.4.1.868.2.5.10.1.8.1.7
Node type: OBJECT-TYPE
Type: InetAddress
Access: read-write
Description: The subnet the ipAddr belongs to.
What is tnIPv4SubnetMask?
This is the subnet mask for this interface's IPv4 address (tnIPv4Addr), in the per-interface IPv4 management table. An admin sets this together with the address when statically configuring one interface on a multi-interface device.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.868.2.5.10.1.8.1.7 snmpwalk -v2c -c public <target> TN-DEV-SYS-IPMGMT-MIB::tnIPv4SubnetMask
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.868.2.5.10.1.8.1.7.1 snmpget -v2c -c public <target> TN-DEV-SYS-IPMGMT-MIB::tnIPv4SubnetMask.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.868.2.5.10.1.8.1.7.1 s <value>
