Enabling the System to Test Connected Cable
You can enable the system to test the cable connected to a specific port. The test result will be returned
in five seconds. 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.

z Currently, the device is only capable of testing the cable status and cable length. For the testing
items 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 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
