In both situations, the Business Policy Switch “autosenses” the speed of the
connected station and, by default, reverts to half-duplex mode. If the connected
station is operating in full-duplex mode, it cannot communicate with the switch.
To correct this mode mismatch problem:
1
Use the Port Configuration screen to disable autonegotiation for the suspect
port (see Chapter 3).
2
Manually set the Speed/Duplex field to match the speed/duplex mode of the
connected station (see Chapter 3).
You may have to try several settings before you find the correct speed/duplex
mode of the connected station.
If the problem persists:
1
Disable the autonegotiation feature at the connected station.
2
Manually set the speed/duplex mode of the connected station to the same
speed/duplex mode you have manually set for the Business Policy Switch
port.
Port interface
Ensure that the devices are connected using the appropriate crossover or
straight-through cable (see Appendix F).
Note:
Nortel Networks recommends that you manually set the Business
Policy Switch port to the desired speed/duplex mode when you connect
to any of the following Nortel Networks products:
