Magnum 3000 Stackable Hubs Installation and User Guide (07/06)

into two logical repeaters with separate

collision domains, while still passing SNMP

management data through the SRC so that the

agent can manage both repeaters. Then, a local

bridge can be installed between the two

repeaters using a port from each (for example,

using a bonus port from each repeater) to

provide traffic service between the

repeaters while maintaining full 10Mbps

bandwidth for the users on each repeater

stack.

segmentation using an SRC

cable

The same result could also be

achieved by installing a Magnum

Bridge Port Module (BPM) into the

Bonus Port of one of the repeaters and

connecting it to a port on the other

repeater.

In another example, eight

3024 hubs in a managed stack are

individually segmented and a switching

hub is used as the traffic center.

Figure 2.3.2b: SRC cables segment a managed stack

for connection to switching hub ports.

This special configuration provides high bandwidth for the users on each 3024 hub, but

also provides the efficiency of a single SNMP agent for all of the 3024s. Note also that

Magnum 3012 units can be used with the special SRC segmenting cable, mixing with the

3024 models in configurations as desired.
