DCB performance
Performance monitoring provides details about the quantity of traffic and errors a specific port or
device generates on the fabric over a specific time frame. You can also use Performance features
to indicate the devices that create the most traffic and to identify the ports that are most
congested.
The Performance menu items launch either SAN or IP performance dialog boxes based on which
tab you select. Note the following points:
•
The DCB configuration dialog box can be launched from either the SAN or IP tab.
•
The appropriate IP Performance tab launches depending on whether you selected a port or a
switch.
Real-time performance graph
You can monitor a device’s performance through a performance graph that displays transmit and
receive data. The graphs can be sorted by the column headers. You can create multiple real-time
performance graph instances.
