acosDeviceIpAddressSubnetMask
Module: ACOS-MIB
OID (symbolic): ACOS-MIB::acosDeviceIpAddressSubnetMask
OID (numeric): 1.3.6.1.4.1.2221.1.1.9.1.1.6
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-write
Description: The subnet mask for the IP address assigned to this device in this slot. A value of '0.0.0.0' will be returned in a GET when the device does not have an IP address assigned to it.
What is acosDeviceIpAddressSubnetMask?
This read-write field holds the subnet mask associated with the device's IP address, defining which destination addresses are on the local network segment. Network engineers configure this alongside the IP address to establish network scope and determine whether packets route locally or through a gateway. A mask of 255.255.255.0 (/24) with IP 192.168.1.100 means the local network is 192.168.1.0/24, and other addresses route through a gateway.
