Broadcast Storm Protection
Some devices in the network may generate broadcast storms, thereby
jamming the network with broadcast packets. It may take about 6-7 seconds
to detect a broadcast storm.
When the Broadcast Storm Protection is Enabled, the system will monitor the
incoming packets to see if that port is enduring a broadcast storm. While
Broadcast Storm is detected, the port will be disabled temporarily and the
frame around the port number will blink. The message zone will show the
message “BRDCST STORM” altering normal display. Every 2 minutes, the
port will be released to see if it is still enduring the broadcast storm.
The Broadcast Storm Protection function is disabled when shipped from
manufacturer. This function can be enabled through the Mini Console. The
command sequence is:
UNIT CONFIG > STORM DET > ENABLE><Enter and hold>
After the command is entered, it will be saved in the EEPROM.
Loop Isolation
Loop Isolation is an important feature of the FSW-0803TX. This condition
could exist if two ports are inadvertently connected to each other causing a
loop.
The switching device can not sustain a loop because it produces Broadcast
Storm thereby jamming the system with looping packets. FSW-0803TX
supports isolating the looped ports. If the function is enabled, the device will
monitor all ports to see if there are any loops.
