Aggregation

Link Aggregation Control Protocol (LACP) IEEE 802.3ad;n

Up to 13 groups ;nUp to 16 ports per group

VLAN

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

Security  

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

Quality of Service

Hardware 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 based

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

Web GUI interface

Built-in switch configuration utility for browser-based device configuration (HTTP/ HTTPs). Supports configuration, system dashboard, maintenance, and monitoring

Dual Image

Dual image provides independent primary and secondary OS files for backup while upgrading

Firmware upgrade

Web browser upgrade (HTTP/ HTTPs) and TFTP;nUpgrade 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.  

Other management

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.

General

Frame sizes up to 9KB supported on Gigabit interfaces

MAC Table

Up to 8K MAC addresses.
