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 – This switch authenticates management access via the
console port or Telnet. 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 the Extensible Authentication
Protocol over LANs (EAPOL) to request user credentials from the 802.1x
client, and then verifies the client’s right to access the network via an
authentication server.
Other authentication options include SSH for secure management access
over a Telnet-equivalent connection, SSL/HTTPS for Web management
access, IP address filtering for SNMP/Telnet management access, and
MAC address filtering for port access.
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 of
packets when port buffer thresholds are exceeded. The switch supports
flow control based on the IEEE 802.3x standard.
Rate Limiting – This feature controls the maximum rate for traffic
transmitted or received on an interface. Rate limiting is configured on
interfaces at the edge of a network to limit traffic into or out of the
network. Traffic that falls within the rate limit is transmitted, while packets
that exceed the acceptable amount of traffic are dropped.
