Description of Software Features
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 2Mbit
for frame buffering. This buffer can queue packets awaiting transmission
on congested networks.
Spanning Tree Protocol – The switch supports IEEE 802.1D
Spanning Tree Protocol. 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, the protocol will choose a single path and disable all others to
ensure that only one route exists between any two stations on the network.
This prevents the creation of network loops. However, if the chosen path
should fail for any reason, an alternate path will be activated to maintain
the connection.
VLANs – This switch supports up to 128 VLANs. A Virtual LAN is a
collection of network nodes that share the same collision domain
regardless of their physical location or connection point in the network. By
segmenting your network into VLANs, you can:
• Eliminate broadcast storms which severely degrade performance in a
flat network.
