Loopback
Function name: Loopback Test
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 sig-
nal 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.
