Siemens SIMATIC NET SCALANCE SC-600 Configuration Manual page 159

Description
The page contains the following boxes:
• DHCP Server
Enable or disable the DHCP server on the device.
Note
To avoid conflicts with IPv4 addresses, only one device may be configured as a DHCP
server in the network.
• Probe address with ICMP echo before offer
When selected, the DHCP server checks whether or not the IP address has already
been assigned. To do this the DHCP server sends ICMP echo messages (ping) to the
IPv4 address. If no reply is received, the DHCP server can assign the IPv4 address.
Note
If there are devices in your network on which the echo service is disabled as default,
there may be conflicts with the IPv4 addresses. To avoid this, assign these devices an
IPv4 address outside the IPv4 address band.
The table has the following columns:
• Select
Select the check box in the row to be deleted.
• Pool ID
Shows the number of the IPv4 address band. If you click the "Create" button, a new
row with a unique number is created (pool ID).
• 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.
