Dhcp Options - Siemens SIMATIC NET SCALANCE S615 Configuration Manual

● Interface
Select a VLAN IP interface. The IPv4 addresses are assigned dynamically via this interface.
The requirement for the assignment is that the IPv4 address of the interface is located in the
subnet of the IPv4 address band. If this is not the case, the interface does not assign any
IPv4 addresses.
● Enable
Specify whether or not this IPv4 address band will be used.
Note
If you enable the IPv4 address band, its settings in this and the other DHCP tabs are grayed
out and can no longer be edited.
● Subnet
Enter the network address range that will be assigned to the devices. Use the CIDR notation.
● Lower IP Address
Enter the IPv4 address that specifies the start of the dynamic IPv4 address band. The IPv4
address must be within the network address range you configured for "Subnet".
● Upper IP address
Enter the IPv4 address that specifies the end of the dynamic IPv4 address band. The IPv4
address must be within the network address range you configured for "Subnet".
● Lease Time (sec)
Specify for how many seconds the assigned IPv4 address remains valid. When half the
period of validity has elapsed. the DHCP client can extend the period of the assigned IPv4
address. When the entire time has elapsed, the DHCP client needs to request a new IPv4
address.
