Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

The IronPort centralized management feature (available via feature key) allows 
you to manage and configure multiple appliances at the same time, reducing 
administration time and ensuring a consistent configuration across your network. 
You do not need to purchase additional hardware for managing multiple 
appliances. The centralized management feature provides increased reliability, 
flexibility, and scalability within your network, allowing you to manage globally 
while complying with local policies.

A cluster is defined as a set of machines that share configuration information. 
Within the cluster, machines (IronPort appliances) are divided into groups; every 
cluster will contain at least one group. A given machine is a member of one and 
only one group. An administrator user can configure different elements of the 
system on a cluster-wide, group-wide, or per-machine basis, enabling the 
segmentation of IronPort appliances based on network, geography, business unit, 
or other logical relationships. 

Clusters are implemented as a peer-to-peer architecture; there is no master/slave 
relationship within a cluster. You may log into any machine to control and 
administer the cluster. (Some configuration commands, however, are limited. See 

.) 

The user database is shared across all machines in the cluster. That is, there will 
be only one set of users and one administrator user (with the associated 
passwords) for an entire cluster. All machines that join a cluster will share a single 
administrator password which is referred to as the admin password of the cluster.
