Configuring The Interval To Perform Statistical Analysis On Port Traffic; Disabling Up/Down Log Output On A Port - H3C S5100-SI Operation Manual

Optical port (including Combo optical port) does not support VCT (virtual-cable-test) function.
Combo electrical port supports VCT function only when it is in UP condition (using undo shutdown
command), normal Ethernet electrical port always supports this function.

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:

Disabling Up/Down Log Output on a Port

An Ethernet port has three physical link statuses: Up, Down, and Administratively Down. For status
transition conditions, refer to the description of the display brief interface command in Basic Port
Configuration Command.
When the physical link status of an Ethernet port changes between Up and Down or Up and
Administratively Down, the switch will generate Up/Down log and send the log information to the
terminal automatically by default. If the status of Ethernet ports in a network changes frequently, large
amount of log information may be sent to the terminal, which consumes more network resources.
Additionally, too frequent log information is not convenient for you to view.
You can limit the amount of the log information sent to the terminal by disabling the Up/Down log output
function on some Ethernet ports selectively. For information about log output settings, refer to the
Information Center module.
