Function name:
Loopback Test
Function description:
In the Loopback Test function, there are two different loopback tests. One is Internal
Loopback Test and the other is External Loopback Test. The former test function will not
send the test signal outside the switch box. The test signal only wraps around in the switch
box. As to the latter test function, it will send the test signal to its link partner. If you do not
have them connected to active network devices, i.e. the ports are link down, the switch will
report the port numbers failed. If they all are ok, it just shows OK.
Note: Whatever you choose Internal Loopback Test or External Loopback Test,
these two functions will interfere with the normal system working, and all
packets in sending and receiving also will stop temporarily.
