Optimizing Twinax Performance for the Client Workstation
To maximize your twinax performance for the client workstation, follow these
recommendations when using the configuration program:
IP Broadcasting Setting
Use the Local or None setting. The Local setting allows the devices on the
twinax subnet to recognize each other. The IP Broadcasting Transparent (or
default) setting allows non-twinax devices to include the twinax subnet in the
Network Neighborhood, and the twinax devices subnet to include the non-
twinax subnet in the Network Neighborhood. However, this function can
degrade twinax performance if the 5500 Control Unit is attached to a large
network.
