Important General Information
=============================
Full-Duplex Operation
The networks drivers support full-duplex operation (that is,
sending and receiving data simultaneously).
WARNING: You MUST be connected to a switched full-duplex
Ethernet hub to use this feature
(this feature disables collision detection).
To enable this feature, see the user guide.
Make sure to use the latest BIOS available for your PC.
Contact the PC manufacturer for more information.
Close down the PC Card Diagnostics before removing
the PC Card, rebooting the PC, or shutting down the PC.
Suspend and Resume Functionality
If your notebook shuts down power to the PC Card slots
during suspend and resume, you may lose network connectivity
or your notebook may be left in an unknown state.
You may need an updated BIOS. Contact your notebook vendor for
more information.

What is DynamicAccess® software?
DynamicAccess software brings intelligence
to the end systems to provide improved
network performance and control. You can
download the latest DynamicAccess
software from the 3Com Web site: www.3com.com.
What is Fast IP?
Fast IP is software that improves performance on switched networks.
Fast IP allows end systems (notebooks and servers) to discover
switched communication paths. By creating switched short cuts,
Fast IP allows end stations to bypass the router and transfer
data across wire-speed switched paths. Fast IP is part of
3Com’s DynamicAccess software.
What are the notebook and network requirements to run
Fast IP?
Client requirements:
Notebook running Windows 98/95, Windows NT (versions 4 or 3.51),
3Com Megahertz LAN PC Card, and the TCP/IP stack.
Network requirements:
Switched path between stations and single broadcast domain.
What are the network configuration requirements for Fast IP?
Fast IP is designed to bypass the router, particularly
where the router is a bottleneck, as well as to leverage
the switched infrastructure. For Fast IP to create short
cuts around routers, there must be a switched
path between source and destination.
What is the performance gain when using Fast IP?
Fast IP bypasses the router to provide increased performance
in switched networks even if there are just a small
number of network nodes using Fast IP.
The performance gain obtained when deploying Fast IP
is directly related to traffic load on
the backbone router. The more traffic is pumped to it,
the bigger the latency and response
time and the higher the performance gain. Internal
tests show performance increases in
the order of 600% when routers are loaded at 70 to 75%.
