Layer2 switching
Spanning Tree Protocol (STP) Standard Spanning Tree 802.1d
  Rapid Spanning Tree (RSTP) 802.1w
G.8032 ERPS <50ms ring protection for industrial ring application
Aggregation Link Aggregation Control Protocol (LACP) IEEE802.3ad; up to 7 groups &
14ports per group
VLAN Support up to 4k VLANs simultaneously (out of 40906 VLAN IDs); Port based
VLAN; 802.1Q tag based VLAN
IGMP v1/v2 snooping IGM limits bandwidth intensive multicast traffic to only the requesters.
Support 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), HTTPS 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 addresses
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
ACLs 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
Qualtiy of Service
Hardware Support 8 hardware queues
Scheduling 8 COS queues per port support strict priority and weighted round-robin
Classifications Port based; 802.1p(PCP) VLAN priority based;
Rate Limiting Ingress policer;egress shaping and rate control;per VLAN,per port and
flow based
Management (Web/ SSL, Telnet/ SSH, ping,
Trivial File Transfer Protocol (TFTP), SNMP, Syslog)
Web GUI Built-in switch configuration utility for browser-based device configuration
(HTTP/ HTTPs). Supports configuration, system dashboard, maintenance, and
Dual Image Dual image provides independent primary and secondary OS files for backup
while upgrading
Firmware upgrade Web browser upgrade (HTTP/ HTTPs) and TFTP;??Upgrade through console port
as well
Port mirroring Traffic on a port can be mirrored to another port for analysis with a
network analyzer or RMON probe. Up to N-1 (N is Switch’s Ports) ports can
be mirrored to single destination port. A single session is supported.
Others Single IP management; HTTP/HTTPs; SSH; RADIUS; DHCP Client; SNTP; cable
diagnostics; ping; syslog; Telnet client (SSH secure support)
Green Ethernet
Green and Energy saving Ethernet (EEE) Compliant IEEE802.3az Energy Efficient Ethernet Task Force. Automatically
turns off power on Gigabit Ethernet RJ-45 port when detecting link down
or Idle of client. Active mode is resumed without loss of any packets when
the switch detects the link up
Cable length detection Adjusts the signal strength based on the cable length. Reduces the power
consumption for cables shorter.
Mac table Up to 32k Mac address
Link Layer Discovery Protocol (LLDP) Used by network devices for advertising their identities, capabilities,
and neighbors on a IEEE 802 local area network, principally wired Ethernet.
