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 Server and DHCP Relay – A DHCP server is provided to assign
IP addresses to host devices. 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 also supported to allow dynamic configuration of local clients
from a DHCP server located in a different network.
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.
Port Trunking – Ports can be combined into an aggregate connection.
Trunks can be manually set up or dynamically configured using IEEE
802.3-2002 (formerly IEEE 802.3ad) Link Aggregation Control Protocol
(LACP). The additional ports dramatically increase the throughput across
