You can enable the system to test the cable connected to a specific port. The test result will be returned 

in five minutes. The system can test these attributes of the cable: Receive and transmit directions (RX 

and TX), short circuit/open circuit or not, the length of the faulty cable.  

Follow these steps to enable the system to test connected cables: 

Enter system view  

— 

Enter Ethernet port view  

interface interface-type interface-number 

— 

Enable the system to test 
connected cables

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. 

 

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: 

Enter system view 

— 

Enter Ethernet port view 

interface interface-type 
interface-number 

— 

Set the interval to perform 
statistical analysis on port traffic 

flow-interval interval 

Optional 

By default, this interval is 300 
seconds.
