   ---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 

    LACP
    ---2 Fast Ethernet +1 Gigabit Ethernet 
        groups
    ---Per-group max 4 members
    ---Provides DA, SA and DA+SA Mac-
        based trunking with automatic link fail-
        over
    GVRP/GARP
    ---802.1q with GVRP/ GARP
    Multicasting
    ---Supports IGMP snooping including
        active and passive mode
       STP/RSTP
    ---802.1d/1w/1s STP

Fast EthernetSwitch

    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.

    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.
