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+).
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.
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
DHCP Relay Option 82 controls 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).
Port Mirroring
The switch can unobtrusively mirror traffic from any port to a monitor port. You can
then attach a protocol analyzer or RMON probe to this port to perform traffic
analysis and verify connection integrity.
Port Trunking
Ports can be combined into an aggregate connection. Trunks can be manually set
up or dynamically configured using Link Aggregation Control Protocol (LACP – IEEE
802.3-2005). The additional ports dramatically increase the throughput across any
connection, and provide redundancy by taking over the load if a port in the trunk
should fail. The switch supports up to 27/16 trunks on the AOS5700-54X and
AOS6700-32X respectively.
