contNetAddressMask
Module: CT-CONTAINER-MIB
OID (symbolic): CT-CONTAINER-MIB::contNetAddressMask
OID (numeric): 1.3.6.1.4.1.52.4.1.1.9.6.1.1.4
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-write
Description: Indicates the subnet mask for the network address of the device for a particular network
What is contNetAddressMask?
This read-write NetworkAddress object holds the subnet mask that corresponds to the device's network address for a particular network. An admin sets this together with contNetAddress to ensure the device correctly interprets which hosts are local versus routed on that management network. For example, after changing contNetAddress to a new subnet, the admin must also update this mask value or the device may miscalculate its local broadcast domain.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.1.1.9.6.1.1.4 snmpwalk -v2c -c public <target> CT-CONTAINER-MIB::contNetAddressMask
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.1.1.9.6.1.1.4.1 snmpget -v2c -c public <target> CT-CONTAINER-MIB::contNetAddressMask.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.1.1.9.6.1.1.4.1 a <value>
