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

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

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.
Jumbo frames Frame sizes up to 9KB supported on Gigabit interfaces
Mac table Up to 8k 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.
