Port Clustering
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 SERIMUX can manage up to 16 slave devices or a maximum 544 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.
To set up the SERIMUX for port clustering you will need to:
• Configure all SERIMUX serial ports
• Assign one SERIMUX as the master clustering device; all other SERIMUXs default to slave devices.
• Import slave configuration to the SERIMUX master device

Configuring Port Clustering
Assigning Master Clustering Mode
To assign a SERIMUX as the master cluster device, do the following:
1. Access the SERIMUX through the web interface. This SERIMUX needs to be the unit to be used as the Master.
2. Under the Clustering heading, choose Configuration.
3. Choose Master from the drop down menu.
Subsequent units will be configured in Slave mode by default.
4. Choose Save & apply.

Configuring Slave Ports on the Master Unit
Ports on slave units are automatically enabled and set to the Telnet protocol. To disable some or all of the ports or to use a
different protocol, make these changes to the slave units before performing the autoconfigure on the slave ports on the master
unit.
To configure the slave serial ports on the master unit, do the following:
1. Access the SERIMUX through the web interface.
2. Under the Clustering heading, choose Configuration.
3. Select the hyperlinked number under Unit ID or the dashed line under IP address.
