Configure DHCP
From the Module Properties dialog box, click the DHCP tab to configure
Dynamic Host Configuration Protocol (DHCP) using these fields:
• Mode—Select from Assigned by Port, Assigned by Pool, Off.
• Subnet Mask—Subnet Mask given to all devices assigned IP addresses with
the 1783-EMS switch.
• Default Gateway—Leave blank if no gateway exists on the network.
• DNS Primary—Leave blank if no DNS server is present on the network.
• DNS Secondary—Leave blank if no DNS server is present on the
network.
• Default Lease Time—7 days by default.
• DHCP Pool Configuration—Used when Assigned by Pool mode is
selected. Assigns the next available IP address from this range of addresses.
• Port Based IP assignment—Associates an IP address with a given port.
Any request coming over that port for an IP address is given the address
associated with the port. Leaving the port blank instructs the 1783-EMS
switch to ignore DHCP requests coming from that port.
IMPORTANT Settings made on the DHCP tab overwrite settings made on the HTML
management interface. If you are scanning the 1783-EMS switch with
Logix software, use the DHCP tab to configure IGMP to avoid confusion.
