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 6K 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 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 255 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.
