 Digital Input and Digital Output
 2 Digital Input (DI)
 2 Digital Output (DO)
 Integrate sensors into auto alarm system
 Transfer alarm to IP network via email and SNMP trap
 Layer 2 Features
 Prevents packet loss with back pressure (half-duplex) and IEEE 802.3x pause frame flow control (full-duplex)
 High performance of Store-and-Forward architecture, and runt/CRC filtering eliminates erroneous packets to optimize
the network bandwidth
 Storm Control support
− Broadcast/Multicast/Unicast
 Supports VLAN
− IEEE 802.1Q tagged VLAN
− Supports provider Bridging (VLAN Q-in-Q, IEEE 802.1ad)
− Private VLAN Edge (PVE)
− Port Isolation
− MAC-based VLAN
− Protocol-based VLAN
− Voice VLAN
− GVRP
 Supports Spanning Tree Protocol
− IEEE 802.1D Spanning Tree Protocol (STP)
− IEEE 802.1w Rapid Spanning Tree Protocol (RSTP)
− IEEE 802.1s Multiple Spanning Tree Protocol (MSTP), spanning tree by VLAN
− BPDU Guard
 Supports Link Aggregation
− 802.3ad Link Aggregation Control Protocol (LACP)
− Cisco ether-channel (static trunk)
− Maximum 5 trunk groups with 10 ports per trunk group
− Up to 20Gbps bandwidth (duplex mode)
 Provides port mirror (many-to-1)
 Port mirroring to monitor the incoming or outgoing traffic on a particular port
 Loop protection to avoid broadcast loops
 Supports ERPS (Ethernet Ring Protection Switching)
 Compatible with Cisco Uni-directional link detection(UDLD) that monitors a link between two switches and blocks the
ports on both ends of the link if the link fails at any point between the two devices
 Link Layer Discovery Protocol (LLDP) and LLDP-MED
 Provides ONVIF for co-operating with PLANET video IP surveillances
