lan1SubnetMask
Module: CMM3-MIB
OID (symbolic): CMM3-MIB::lan1SubnetMask
OID (numeric): 1.3.6.1.4.1.161.19.3.4.3.3
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-write
Description: LAN 1 subnet mask.
What is lan1SubnetMask?
This read-write IpAddress holds the subnet mask paired with lan1Ip, defining which addresses on LAN 1 the CMM-III considers local versus reachable only through the default gateway. An admin needs this set correctly alongside lan1Ip and defaultGateWay for the unit to route management traffic properly. Misconfiguring lan1SubnetMask, for instance leaving it too broad, could make the CMM-III fail to route traffic to remote monitoring stations through the gateway as expected.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.161.19.3.4.3.3 snmpwalk -v2c -c public <target> CMM3-MIB::lan1SubnetMask
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.161.19.3.4.3.3.1 snmpget -v2c -c public <target> CMM3-MIB::lan1SubnetMask.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.161.19.3.4.3.3.1 a <value>
