For the testingitems that are currently not supported, “-” is displayed in the corresponding output fields.z Cable test cannot be performed on an optical port.Configuring the Interval to Perform Statistical Analysis on Port TrafficBy performing the following configuration, you can set the interval to perform statistical analysis on thetraffic of a port.When you use the display interface interface-type interface-number command to display theinformation of a port, the system performs statistical analysis on the traffic flow passing through the portduring the specified interval and displays the average rates in the interval. For example, if you set thisinterval to 100 seconds, the displayed information is as follows:Last 100 seconds input: 0 packets/sec 0 bytes/secLast 100 seconds output: 0 packets/sec 0 bytes/secTable 1-9 Set the interval to perform statistical analysis on port trafficOperation Command DescriptionEnter system view system-view —Enter Ethernet port view interface interface-typeinterface-number —Set the interval to performstatistical analysis on porttrafficflow-interval intervalOptionalBy default, this interval is 300seconds.Disabling Up/Down Log Output on a PortAn Ethernet port has two physical link statuses: UP and Down. When the physical link status of anEthernet port changes, the switch will send log to the log server, which in turn acts accordingly. If thestatus 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 logoutput function on Ethernet ports.
