Introduction
Port clustering is the ability to manage many serial ports on one or multiple slave devices from one
master device using a single IP address. For instance, the Digi CM unit can manage up to 16 slave
devices or a maximum 816 serial ports with one Master device. Ports can be configured either
collectively or individually depending on user preference. Each master and slave device is
configured separately; they cannot be configured from one master console.
A secondary IP address can be specified to put all slaves on a private network. The secondary IP
option can be found under
Network
–>
IP configuration
.
To set up the Digi CM unit for port clustering you will need to:
▪
Configure all the Digi CM serial ports.
▪
Assign one Digi CM unit as the master clustering device; all other Digi CM units default to slave
devices.
▪
Import slave configuration to the Digi CM unit’s master device.

Access the Digi CM unit through the web interface. This Digi CM unit needs to be the unit you
want as the Master.
2
Under the

heading, choose
Configuration
.
3
Choose Master from the drop down menu.
Subsequent units will be configured in Slave mode by default.
