Use the full-duplex mode on ports whenever possible to double the throughput of switch
connections. Flow control should 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 (incorporated in IEEE
802.3-2002).
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 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 5 trunks.
STORM CONTROL
Broadcast, multicast and unknown unicast storm suppression prevents traffic from
overwhelming the network. When enabled on a port, the level of broadcast traffic passing
through the port is restricted. If broadcast traffic rises above a pre-defined threshold, it will
be throttled until the level falls back beneath the threshold.
STATIC ADDRESSES
A static address can be assigned to a specific interface on this switch.
Static addresses are bound to the assigned interface and will not be moved. When a static
address is seen on another interface, the address will be ignored and will not be written to
the address table. Static addresses can be used to provide network security by restricting
access for a known host to a specific port.
