CHANGING CONFIGURATION
This chapter describes how to display and change
configuration settings for the 3C905B-TX adapter using
the 3Com NIC Diagnostics program.
Before you change the settings, contact your system
administrator.
Configuration Settings
Table 4-1 lists each configuration option, the default
setting, and the available settings.
.
CAUTION: Before setting the 3C905B-TX adapter for
full-duplex, make sure that the switch port is also set to
full-duplex or supports full-duplex and auto-negotiation
(NWay).
Full-duplex at 100 Mbps improves the performance of
switch (hub) connections. The 3C905B-TX adapter
supports full-duplex at 10 or 100 Mbps. If the switch
supports the NWay feature and full-duplex, the 3C905B-TX
adapter automatically runs in full-duplex.
