broadcast domain, which may result in broadcast storm and so may greatly degrade the
switch performance. Enabling Broadcast Storm Control can better protect the switch
from broadcast storm. Note the difference of this command in 10Gb ports and other
ports. If the allowed traffic is set to 3, this means allow 3,120 packets per second and
discard the rest for 10Gb ports. However, the same setting for non-10Gb ports means
to allow 3 broadcast packets per second and discard the rest.
Example: Setting ports 1/0/8-10 (1000Mbps) allow 3 broadcast packets per second.
Switch(config)#interface ethernet 1/0/8-10
Switch(Config-Port-Range)#storm-control broadcast 3
1.1.19 virtual-cable-test
Command: virtual-cable-test interface (ethernet |)IFNAME
Function: Test the link of the twisted pair cable connected to the Ethernet port. The
response may include: well, short, open, fail. If the test information is not well, the
location of the error will be displayed (how many meters it is away from the port).
Parameter: <interface-list>: Port ID
Command Mode: Admin Mode.
Default Settings: No link test.
Usage Guide: The RJ-45 port connected with the twisted pair under test should be in
accordance with the wiring sequence rules of IEEE802.3, or the wire pairs in the test
result may not be the actual ones. On a 100M port, only two pairs are used: (1, 2) and
(3, 6), whose results are the only effective ones. If a 1000M port is connected to a
100M port, the results of (4, 5) and (7, 8) will be of no meaning. The result may have
deviations according to the type of the twisted pair, the temperature, working voltage
and other conditions. When the temperature is 20 degree Celsius, and the voltage is
stable without interference, and the length of the twisted pair is not longer than 100
meters, a deviation of +/-2 meters is allowed. When the port is at Link UP status, a
deviation of +/-10 meters is allowed. Notice: the test procedure will block all data flow
on the line for 5-10 seconds, and then restore the original status.
Notice: combo port supports VCT function detection only at copper cable port mode,
100M port does not diagnose the link length at Link UP status.
568A wiring sequence: (1 green white, 2 green), (3 orange white, 6 orange), (4 blue, 5
blue white), (7 brown white, 8 brown).
568B wiring sequence: (1 orange white, 2 orange), (3 green white, 6 green), (4 blue, 5
blue white), (7 brown white, 8 brown).
Example: Test the link status of the twisted pair connected to the 1000M port 1/0/25.
