8.1  High Availability

High availability occurs when one or more ESs takes over for an ES that has become unavailable in 
a multiple-server installation. 

Once an ES becomes unavailable, the other ESs take over enforcement from the ES that is now 
unavailable. All ESs participate in enforcement. The MS provides notification in the user interface 
at the top of the 

Home

 window. For example, if an ES is unavailable, the notification indicates that 

at the top of the 

Home

 window.

When Novell ZENworks Network Access Control is installed inline in a multiple-server 
configuration (

Figure 8-1 on page 226

), the multiple ESs form a network loop (an undesired 

condition). The Spanning Tree Protocol (STP) detects the loop and closes one of the offending ports 
on the switch based on the switch configuration. If an ES becomes unavailable, the switch 
reconnects so that there is always a path from the VPN to an ES. All of the ES firewalls 
continuously stay in sync with each other.
