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.
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 16K 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 1 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
