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.

Subscriber Interface
1-24 10/100Mbps Fast Ethernet ports. / 25,26 are Gigabit TP/ SFP Fiber auto sense
Auto-Negotiation and Auto-MDIX
Backpressure flow control for half duplex / 802.3x flow control for full duplex.
Connector: 24 RJ-45 and 25,26 dual media (RJ-45/SFP)
Switching capacity:
Non-blocking switch fabric supports up to 24FE+2GbE, ports
8K MAC addresses / 256k packet buffer and 128k control memory
VSM (Virtual Stacking Management)
Supports 16 switches can be Stack / managed via one IP address, just like software stacking
Low cost and easily to establish network environment, not extra hardware require.
Not center on the physical location of writing closets
Bandwidth Control

Port Mirroring
Support 1: N RX port miroingrr
Supports port sniffer function with 3 modes: (TX Monitor, RX Monitor and TX-RX pair Monitor Mode)
Restricted Group
Can decide the direction of transmitting packets for the specific port

Network Security
802.1x access control / Isolated group / Restricted group / Management Access Policy Control / Static mac, to limit
which mac addresses can pass through or not / Mac addresses learning limit, to set up the maximum amount of mac
that each port can learn
