12CHAPTER 1: SYSTEM AND SETUP OVERVIEW
■Resilient links
Resilient links technology protects your network against an individual link or device failure by providing a secondary backup link that is inactive until it is needed.
■Manageability
The CoreBuilder 9400 provides full support for VLANs and
System Management
The CoreBuilder 9400 system includes integrated management to provide fault tolerance and maximum network availability. This management is accessible in three ways:
■CoreBuilder 9400 Administration Console
■Standard network management applications based on SNMP, such as 3Com’s Transcend applications, Sun’s SunNet Manager, HP’s OpenView, and IBM’s NetView AIX applications
■Web Management suite of applications, with forms for many management tasks, charts and wizards to help you configure and monitor your system, and online Help (separately installed) give you instant information about your configuration choices.
Network Configuration Example
This section discusses one way to place the
CoreBuilder 9400 in your network.
Speeding Up Server Access
To centralize your servers for easier service and support, use a configuration like the one shown in Figure 3.
Suppose that all of your organization’s servers are located in that physical space. These servers must support a large number of clients that are distributed throughout the organization’s campus. The clients are switched Fast Ethernet desktops.
First, you can multiplex the traffic from each group of desktop clients into one
Each SuperStack II 3900 can, in turn, pass its traffic along to a CoreBuilder 9400, which multiplexes the traffic into Gigabit Ethernet streams for the servers.
This architecture eliminates bottlenecks caused by each Fast Ethernet device as it vies for access to the server.
You can also use the CoreBuilder 9400 for many other applications, such as to consolidate LAN backbones or to provide more flexible trunking configurations.
