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 4 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.
IEEE 802.1D Bridge – The switch supports IEEE 802.1D transparent bridging.
The address table facilitates data switching by learning addresses, and then
filtering or forwarding traffic based on this information. The address table supports
up to 8K addresses.
Store-and-Forward Switching – The switch copies each frame into its memory
before forwarding them to another port. This ensures that all frames are a
standard Ethernet size and have been verified for accuracy with the cyclic
redundancy check (CRC). This prevents bad frames from entering the network
and wasting bandwidth.
To avoid dropping frames on congested ports, the switch provides 8 MB for frame
buffering. This buffer can queue packets awaiting transmission on congested
networks.
Spanning Tree Protocol – The switch supports these spanning tree protocols:
Spanning Tree Protocol (STP, IEEE 802.1D) – This protocol adds a level of fault
tolerance by allowing two or more redundant connections to be created between a
pair of LAN segments. When there are multiple physical paths between segments,
