 To analyse a specific link, you can use the MAC burst analysis. This is shown in the second tab '''MACs''' in the burst analysis module. It allows to set a specific receive and send bandwidth for a certain MAC address. Up to five MAC addresses can be analysed. If you have an uplink, simply use the Router´s MAC address here and then specify the maximum receive and send rate of the Router´s uplink.
-In this example, we configured maximum values of 250 MBit/s for the downlink and 40 MBit/s for the uplink for the router MAC address.

-Please note that the burst analysis is done with 1 millisecond resolution by default. In our example, the router is connected with 1 GBit/s and it can receive more than the configured uplink bandwidth. This is shown in the display as an utilization of ">> 100%" and indicates that a burst that might not be able to be handled by this uplink.

 == Advantage for Mirror Port and Packet Brokers ==
 The MAC burst detection can be used for a specific end device ( a file server,... ) or for the gateway of an uplink ( router,... ). It allows to monitor links and end devices even in out-of-band installations.
