ctDhcpIfSubnetMask
Module: CTRON-DHCP-MIB
OID (symbolic): CTRON-DHCP-MIB::ctDhcpIfSubnetMask
OID (numeric): 1.3.6.1.4.1.52.4.2.2.2.3.1.2.12.2.2.1.1.6
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-write
Description: This is the subnet mask of the IP subnet which is being served by this interface of the DHCP server.
What is ctDhcpIfSubnetMask?
ctDhcpIfSubnetMask is a read-write IP address giving the subnet mask of the IP subnet being served by this interface of the DHCP server. An admin sets this to match the actual subnet mask in use on that network, since an incorrect mask here would cause the server to hand out addressing information inconsistent with the real subnet boundaries. For example, an admin configuring DHCP for a /23 subnet would set ctDhcpIfSubnetMask to 255.255.254.0 to match that subnet's actual boundaries.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.1.2.12.2.2.1.1.6 snmpwalk -v2c -c public <target> CTRON-DHCP-MIB::ctDhcpIfSubnetMask
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.1.2.12.2.2.1.1.6.1 snmpget -v2c -c public <target> CTRON-DHCP-MIB::ctDhcpIfSubnetMask.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.2.2.2.3.1.2.12.2.2.1.1.6.1 a <value>
