SS-1200-S, SS-2200-S and SS-4200-S Series Link Aggregating Taps72

7.1.2 Utilization greater than 50 percent (Telnet configuration example)

PREMISE: Utilization increases due to network congestion caused by users attempting to use

capacity concurrently and fanning multiple devices into a single port contending for bandwidth.

Pushing the limits of speed and bandwidth utilization increases closer to the core of a network,

where a more constant stream of data is the norm.

When bandwidth utilization increases greater than 50 percent capacity, the application example

'Utilization less than 50 percent ' is no longer a reliable answer to the analysis solution.

This network application example consists of users distributed across two workgroup switches that

allows end users access to the server farm via a server switch. The server switch and end users

utilization is greater than 50 percent during peak load periods. The security department wants to

view all server bound access from the users and view user bound traffic from the server.

GOAL: This application will use a SS-1204BT-BT-S as follows:

1. View user traffic to and from the servers.

2. Provide access for security tool.

The first goal requires tapping the link between the workgroup switch and the server switch. A

power fault tolerant tap does not bring down the network link if the tap fails. The tap will allow

better visibility to user-server traffic.

The second goal involves replicating traffic from the access method developed previously. The SS-

1204BT-BT-S acts as a standard tap, replicating each side of the network traffic to a single output

port for the security tool.
