Configuring the Interval to Perform Statistical Analysis on Port Traffic

By performing the following configuration, you can set the interval to perform statistical analysis on the
traffic of a port.
When you use the display interface interface-type interface-number command to display the
information of a port, the system performs statistical analysis on the traffic flow passing through the port
during the specified interval and displays the average rates in the interval. For example, if you set this
interval to 100 seconds, the displayed information is as follows:
Last 100 seconds input:
Last 100 seconds output:
Follow these steps to set the interval to perform statistical analysis on port traffic:

Enabling Giant-Frame Statistics Function

The giant-frame statistics function is used to ensure normal data transmission and to facilitate statistics
and analysis of unusual traffic on the network.
Follow these steps to enable the giant-frame statistics function:
To do...
Enter system view
Enable the giant-frame
statistics function

Setting the Port State Change Delay

During a short period after you connect your switch to another device, the connecting port may go up
and down frequently due to hardware compatibility, resulting in service interruption.
To avoid situations like this, you may introduce a port state change delay.
