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 RMON-1, as well as a roving analysis
port through SNMP management.
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 higher-bandwidth stream
(trunk) through a SuperStack II Switch 3900.
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.
