Cisco Systems OL-4344-01 manual Simple Flat-Based Server Load Balancing Configuration

Chapter 1 About Cisco IP Solution Center

Security Requirements for MPLS VPNs

•The Processing server can be added dynamically. The Watchdog will discover their existence when you start up ISC.

•Each Collection server is responsible for a set of collection zones. Each zone has one Collection Server.

•Both Processing servers and Collection servers failover to the Master server automatically.

•Each device belongs to a zone, but a device can be relocated to a different zone as needed.

If the service provider has implemented one or more Processing servers or Collection servers, all the servers—Master, Processing, and Collection servers—are listed in the Administration Control Center.

The Remote server can be installed from the Control Center as well.

All Remote servers are monitored by Watchdogs. Remote Watchdogs report statistics to the Master Watchdog. You can start and stop all the servers from the Administration Control Center. Logs are available for viewing in real time.
