Layer 2 Switching

Spanning Tree

Protocol (STP)

Standard Spanning Tree 802.1d

Rapid Spanning Tree (RSTP) 802.1w

G.8032 ERPS <50ms ring protection for industrial high reliable application

Link Aggregation Control Protocol (LACP) IEEE 802.3ad;

Up to 13 groups

Up to 16 ports per group


Support up to 4K VLANs simultaneously (out of 4096 VLAN IDs)

Port-based VLAN

802.1Q tag-based VLAN

IGMP v1/v2 snooping

IGMP limits bandwidth-intensive multicast traffic to only the requesters;

supports 1024 multicast groups (source-specific multicasting is not supported)


Secure Shell

(SSH) Protocol

SSH secures Telnet traffic in or out the switch, SSH v1 and v2 are supported

Secure Sockets

Layer (SSL),


SSL encrypts the http traffic, allowing advance secure access to the

browser-based management GUI in the switch

Port Security

Locks MAC Addresses to ports, and limits the number of learned MAC


DHCP Snooping

prevent unauthorized configuration and use of IP addresses, while providing

support for IP Source Guard and ARP detection

IP Source Guard Prevents datagram with spoofed addresses from being in the network
ARP Inspection Prevent ARP spoofing attacks and ARP
Storm control

Prevents traffic on a LAN from being disrupted by a broadcast, multicast, or

unicast storm on a port


Support for up to 256 entries; Drop or rate limitation based on source and

destination MAC, VLAN ID or IP address, protocol, port, differentiated services code point (DSCP) / IP precedence, TCP/ UDP source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, IGMP packets, TCP flag

Quality of Service


Priority Queue

Support 8 hardware queues
Scheduling 8 COS queues per port support strict priority and weighted round-robin (WRR)
Classification Port based; 802.1p(PCP) VLAN priority based;
Rate Limiting

Ingress policer;egress shaping and rate control;per VLAN,per port and flow


Management (Web/ SSL, Telnet/ SSH, ping, Trivial File Transfer Protocol (TFTP), SNMP, Syslog)



Built-in switch configuration utility for browser-based device configuration

(HTTP/ HTTPs). Supports configuration, system dashboard, maintenance, and
