When Virtual Ports is selected, the following form appears.The virtual ports form allows you to perform clustering of the console server units. The console server clustering is designed to allow a large number of serial ports (up to 1024) to be configured and virtually accessed through one IP address.You can use one console server as the master to control other console servers as Slaves. The ports on the Slave unit(s) appear as if they are part of the master.NOTE: Multiple IPDUs should only be connected and daisy-chained through the serial port of the master console server when you are configuring a cluster.This section shows you how to define and configure the Slaves.When you click the Add or Edit button on the Ports - Virtual Ports form, the following dialog box appears.
The first unallocated port number for the Slave. For example, if the master unit has 16 ports, ports 1-16 are allocated. The First Local Port Number is then 17. The IP address for the master console server or it can be the global IP address of the cluster in the network. The first TCP port number for the Slave. For example, if the master unit has 16 ports, the allocated TCP port numbers to the master are 7001-7016. The First Local TCP Port No. is then 7017. This is a virtual TCP port number. Once you have configured the Slave console server and defined the cluster parameters, the Slave serial ports and the connected devices are accessible from the master console server under Applications - Connect - Serial pull-down menu.NOTE: The console servers should be connected individually to an IP network. The units should not be cascaded.
1. Go to Ports - Virtual Ports in Expert mode and click the Add button to add new Slave ports or click the Edit button to edit a Slave port. The New/Modify Port dialog box appears.
2. From the pull-down menu select the number of ports that you wish to assign as Slaves. Choices are 1, 4, 8, 16, 32 and 48.
7.
8. Select the communication protocol between the master and the Slave from the Protocol pull-down menu. The options are Telnet or SSH.Selecting the Port Names button on the New/Modify Port dialog box, displays the form shown in the following figure.Use this form to assign a name or alias to the Slave ports in the cluster. Use a naming convention for effective management of the console server and the connected devices on your network.
