Description: Subnet Mask is Dhcp option 1. Default = 255.255.255.0 There is no ability to configure this option in the general option table.
What is cigDhcpServersPoolSubnetMask?
This field holds the subnet mask value that the device's built-in DHCP server hands out to clients as DHCP option 1, defaulting to 255.255.255.0 (a /24 network). Because this option has its own dedicated field rather than going through the general DHCP option table, changing it here is the only way to adjust the subnet mask leased to clients on this pool. For example, setting this to 255.255.255.128 would split the pool into /25-sized subnets, so clients getting addresses from this pool would compute a smaller broadcast domain than the default /24.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.6889.2.1.16.2.2.1.1.10 snmpwalk -v2c -c public <target> CIG-SERVERS-MIB::cigDhcpServersPoolSubnetMask
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.6889.2.1.16.2.2.1.1.10.1 snmpget -v2c -c public <target> CIG-SERVERS-MIB::cigDhcpServersPoolSubnetMask.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.6889.2.1.16.2.2.1.1.10.1 a <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> cigDhcpServersPoolSubnetMask.1
