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 SMC8724ML3 and
SMC8748ML3 provide 2 MB and 4 MB, respectively, for frame buffering.
This buffer can queue packets awaiting transmission on congested
networks.
