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
802.3ad Link Aggregation Control Protocol (LACP). 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 6 trunks.
Broadcast Storm Control – Broadcast suppression prevents broadcast
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.
