Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

The Cisco centralized management feature 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 (Cisco 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 Cisco 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.
