High Availability
Network VirusWall Enforcer 2500 achieves high availability (HA) using the
following solutions:

Understanding and Testing the Network
VirusWall Enforcer 2500 Deployment
section for details on how to apply a failover
and failopen solution in a Network VirusWall Enforcer 2500 deployment. You can
only configure failover and failopen settings from the Preconfiguration console.
Redundant Ports and Devices
Port redundancy allows you to use a redundant physical link implementation for
securing maximum network uptime and reliability. A mesh network is the target
topology for the redundant port solution.
In a port redundancy solution, Network VirusWall Enforcer 2500 provides two ports
to connect to the up-link and downlink switches in dual paths.
Applying a port redundant solution requires the completion of the following tasks:
1.
Allocate port group 1 with two (2) ports
2.
Allocate port group 2 with two (2) ports
3.
Configure redundancy port groups with port groups 1and 2
To enable the failover fault-tolerance solution, redundant devices usually accompany
the port redundancy configuration. In a port-redundant Network VirusWall Enforcer
2500 implementation, multiple connection paths exist, each with a redundant device,
to help ensure that the connection is still viable even if one (or more) paths fail. The
capacity for automatic failover means that the device can maintain normal functions
despite the inevitable interruptions caused by problems with equipment. In a failover
deployment, if one of the devices in a failover pair fails, the other Network VirusWall
Enforcer 2500 device maintains all settings, connections, and sessions.
