Full-duplex mode eliminates both the link's collision domain and the
need for collision detection. As a result, full-duplex point-to-point links
can be much longer than half-duplex links.
To configure a port for full-duplex operation:
The items available on the top-level menus in this section vary depending on
your level of access and on the modules installed in your CoreBuilder 6000
chassis.
1 From the top level of the Administration Console, enter:
ethernet fastEthernet duplexMode
A prompt similar to the following one appears:
Select slot(s) (10-12|all):
This prompt indicates that the CoreBuilder 6000 system contains
configurable Fast Ethernet ports in slots 10, 11, and 12.
2 Enter the number(s) of the slot(s) that contain ports that you want to
set to full-duplex mode:
10-12
For each slot you enter, the system prompts you for specific port
numbers:
Select Ethernet port(s) (1-8,all):
3 Enter the number(s) of the port(s) that you want to configure:
1,2,5-7
The system displays this message:
Warning: Changing mode to full duplex disables collision
detection. The device connected to this port must be
configured for the same duplex mode.
Do you want to change the duplex mode (n,y) [y]:
The CoreBuilder 6000 system does not support autonegotiation of duplex
mode between devices. You must configure any device attached to this port
to the same duplex mode as the port.
4 Enter
for Yes,
