server to verify the client’s right to access the network via an authentication
server (i.e., RADIUS 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/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, 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.
Port Configuration – You can manually configure the speed and 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.
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.
