z
Optical port (including Combo optical port) does not support VCT (virtual-cable-test) function.
z
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: 0 packets/sec 0 bytes/sec
Last 100 seconds output: 0 packets/sec 0 bytes/sec
Follow these steps to set the interval to perform statistical analysis on port traffic:
