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: 0 packets/sec 0 bytes/sec
Last 100 seconds output: 0 packets/sec 0 bytes/sec

Disabling Up/Down Log Output on a Port
An Ethernet port has two physical link statuses: UP and Down. When the physical link status of an
Ethernet port changes, the switch will send log to the log server, which in turn acts accordingly. If the
status of Ethernet ports in a network changes frequently, large amount of log information may be sent,
which increases work load of the log server and consumes more network resources.
You can limit the amount of the log information sent to the log server by disabling the Up/Down log
output function on Ethernet ports.
