Description of Software Features

The switch provides a wide range of advanced performance enhancing features.
Flow control eliminates the loss of packets due to bottlenecks caused by port
saturation. Broadcast storm suppression prevents broadcast traffic storms from
engulfing the network. Port-based and private VLANs, plus support for automatic
GVRP VLAN registration provide traffic security and efficient use of network
bandwidth. CoS priority queueing ensures the minimum delay for moving real-time
multimedia data across the network. While multicast filtering provides support for
real-time network applications. Some of the management features are briefly
described below.
Configuration Backup and Restore – You can save the current configuration
settings to a file on a TFTP server, and later download this file to restore the switch
configuration settings.
Authentication – The switch supports Authentication, authorization, and accounting
(AAA) as the main framework for configuring access control on the switch. AAA
provides accounting and billing for IEEE 802.1X authenticated users that access the
network, and for users that access management interfaces through the console and
Telnet. Authorization is provided for users that access management interfaces on
the switch through the console and Telnet. The AAA features use RADIUS or
TACACS+ server groups for centralized and robust administration control.
Other authentication options include HTTPS for secure management access via the
web, SSH for secure management access over a Telnet-equivalent connection, IP
address filtering for SNMP/web/Telnet management access, and MAC address
filtering for port access.
Access Control Lists – ACLs provide packet filtering for IP frames (based on
address, protocol, or TCP/UDP port number) or any frames (based on MAC address
or Ethernet type). ACLs can be used to improve performance by blocking
unnecessary network traffic or to implement security controls by restricting access to
specific network resources or protocols.
Port Configuration – You can manually configure the speed, duplex mode, and
flow control used on specific ports, or use auto-negotiation to detect the connection
settings used by the attached device. Use the full-duplex mode on ports whenever
possible to double the throughput of switch connections. Flow control should also be
enabled to control network traffic during periods of congestion and prevent the loss
