Introduction
Clustering is a way to provide access to the serial ports of many IOLANs
through a single IP address.

Clustering Slave List

Overview
The IP address that will be used to access all clustered serial ports will be that of the Master IOLAN
in the cluster. All other IOLANs in the cluster will be referred to as Slave IOLANs. Users can also
access slave serial ports using EasyPort Web; EasyPort Web is automatically launched when a user
types in the IP address of the Master IOLAN in a web browser. If the user has admin pri vil eges, the
WebManager will first be displayed with an option to proceed to EasyPort Web.
The Clustering Slave List window display s the slave IOLAN entries and the numb er of ports on
those slave IOLANs.
