Dynamic IP Address Assignment by Port
The 1783-EMS switch has the ability to assign IP addresses based on the port
where the device is connected. When used properly, this feature provides for easy
replacement of Ethernet equipment on the factory floor.
Use these steps to set up dynamic IP address assignment by port.
1. Establish a connection with the 1783-EMS switch.
2. Click Network Services Setup and DHCP Configuration.
3. From the DHCP Server pull-down menu, choose On - Assigned by Port.
By default, this setting is off.
IMPORTANT If multiple devices are connected to a port with an uplink to another switch,
the IP address is sent to the first device to request it from the port. If a field is
set to an address of 0.0.0.0, a DHCP request on the port is ignored.
Most applications with programmable controllers do not require changes to
the DNS, domain name, and lease time fields. If these functions do not apply to
your network, leave these fields at their default value.
