and Diffserv(IPv4/IPv6) based QoS
packet classification
---Supports four level priority queues to
prioritize in-bound and out-bound
traffic
---Supports two scheduling, WRR and
Strict

modes:
(TX Monitor Mode, RX Monitor Mode
and TX-RX pair Monitor Mode).
Isolated Group
---Provide one group allows certain
ports to be designated as protected.
Restricted Group
---Can decide the direction of
transmitting packets for the specific
port
Restricted Group

transmission and reception of packets can be guaranteed in event of any fail-
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.
