Description of Software Features

Some of the management features are briefly described below.
Configuration Backup
and Restore
You can save the current configuration settings to a file on the management station
(using the web interface) or an FTP/TFTP server (using the web or console
interface), and later download this file to restore the switch configuration settings.
Authentication This switch authenticates management access via the console port, Telnet, or a web
browser. User names and passwords can be configured locally or can be verified via
a remote authentication server (i.e., RADIUS or TACACS+). Port-based
authentication is also supported via the IEEE 802.1X protocol. This protocol uses
Extensible Authentication Protocol over LANs (EAPOL) to request user credentials
from the 802.1X client, and then uses the EAP between the switch and the
authentication server to verify the client’s right to access the network via an
authentication server (i.e., RADIUS or TACACS+ server).
Other authentication options include HTTPS for secure management access via the
web, SSH for secure management access over a Telnet-equivalent connection,
SNMP Version 3, IP address filtering for SNMP/Telnet/web management access.
MAC address filtering and IP source guard also provide authenticated port access.
While DHCP snooping is provided to prevent malicious attacks from insecure ports.
While PPPoE Intermediate Agent supports authentication of a client for a service
provider.
Access Control Lists ACLs provide packet filtering for IP frames (based on address, protocol, TCP/UDP
port number or TCP control code) or any frames (based on MAC address or Ethernet
type). ACLs can by used to improve performance by blocking unnecessary network
traffic or to implement security controls by restricting access to specific network
resources or protocols.
DHCP Relay Since DHCP uses a broadcast mechanism, a DHCP server and its client must
physically reside on the same subnet. Since it is not practical to have a DHCP server
on every subnet, DHCP Relay is supported to allow dynamic configuration of local
clients from a DHCP server located in a different network. DHCP Relay Option 82 is
also provided to control the processing of Option 82 information in DHCP request
packets relayed by this device.
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 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 of
packets when port buffer thresholds are exceeded. The switch supports flow
control based on the IEEE 802.3x standard (now incorporated in IEEE 802.3-2002).
