---Flooding unknown vlan frame setting,
can flood packet with some vlan tag
associated to a invalid/inactive vlan
---In tag-base VLAN, supports egress/
ingress packet filter
---Q-in-Q is an efficient method for
enabling Subscriber Aggregation
VSM(Virtual Stacking Management)
----Up to 16 switches can be managed
via Single IP
----Virtual stacking, no extra stacking
hardware is required
----Distributed stacking, no physical
central wiring closet is needed
QoS
---Port Based, 802.1p , TOS 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
---Supports priority in a Q-in-Q tag
Broadcast Storm
---Multicast/Broadcast/Unknown-Unicast
Storm suppression
Port Mirroring
---Support 1: N RX port mirroring
---Supports port sniffer function with 3
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
Rate Limit
---Ingress rate limit:
Port 1~24: 66k up to 100Mbps
Port 25, 26: 66k up to 1000Mbps
---Egress rate limit:
Port 1~24: 66k up to 100Mbps
Port 25, 26: 66k up to 1000Mbps

2 Dual Media ports for flexible fiber connection
Ports 25, 26 dual media ports 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/GBIC
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
traffic.
restrict excess
Threshold values are available to control the rate limit for each port. Packets
are discarded if the count exceeds the configured upper threshold.
