Loop Detect
Loop Detect is an important feature of the Switch. A loop is created if two
ports are inadvertently connected to each other. If a loop is detected, a
message indicating so will be sent to the Console Management menu
Spanning Tree Protocol (STP) Port Configuration. Please see the section
titled Device Control in Chapter 5, Console Management. A message will
also be sent to the same menu in the Web Management interface.
A switching device can not sustain a loop because it produces a broadcast
storm thereby jamming the system with looping packets. The Switch supports
looped port detection. If the function is enabled, the Switch will search for
looped ports when the Port Status is being checked.
Loop Detect is disabled at the time the switch is shipped from manufacturer.
You have to enable the function through the Front Panel Display. The
command sequence is:
UNIT CONFIG > LOOP DETECT > ENABLE><
Enter
>
After the command is entered, it will be saved in the EEPROM.
