Clusters and Servers
Overview

Overview
NAC 800 uses clusters and servers. A "cluster" is a logical grouping of one or
more ESs that are managed by one MS.
A single-server installation is one where the MS and ES are on one server. The
ES is assigned to a Default cluster. This configuration is illustrated in figure 2-
1.
A multiple-server installation is one where the MS is on one server and there
are one or more ESs on separate servers. Each ES must be assigned to a
cluster. This configuration is illustrated in figure 2-2.
The responsibilities of the MS and ES are as follows:

The quarantine method is defined per cluster; all of the ESs in a given cluster
use the same quarantine method (Inline, DHCP, or 802.1X). When using
multiple clusters, each cluster can have a different quarantine method. Clus-
ters cooperate to test and control access to the network, although the ESs in
each cluster are not able to communicate with any ES in any other cluster.
