over switch on the network.
2 Dual Media for Flexible Fiber Connection
Dual media port 25 and 26 are provided for flexible fiber connection. You can
select to install optional transceiver modules in these slots for short, medium
or long distance fiber backbone attachment. Use of the SFP will disable their
corresponding built-in 10/100/1000Base-T connections.
Broadcast/Multicast/Unknown-unicast Storm Control
To limit too many broadcast/multicast/unknown-unicast flooding in the network,
broadcast/multicast storm control is used to restrict excess traffic. Threshold
values are available to control the rate limit for each port. Packets are
discarded if the count exceeds the configured upper threshold.
