Port Clustering
Chapter 13 103
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 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 for port clustering you will need to:
• Configure all Digi CM serial ports
• Assign one Digi CM as the master clustering device; all other Digi CMs
default to slave devices.
• Import slave configuration to the Digi CM master device
