Each row represents a subnet. The subnets of a DHCP server instance
cannot overlap.
If the local user database defines a pool, then any subnet
of that pool is used to provide a free IP address.
If tmnxDhcpServerCfgUseGiAddress is set to 'true(1)', the Gateway IP
address is used to select the subnet that is used to provide
a free IP address.
Entries in this table can be created or deleted via SNMP operations.
