SET BPORT_MAU
AUTO_POLARITY
Use the SET BPORT_MAU AUTO_POLARITY command to instruct
CoreBuilder 5000 10BASE-T SwitchModules to automatically switch the polarity
of twisted-pair cabling. By default, autopolarity is enabled on 10BASE-T
SwitchModules.
Format
Example
The following command disables autopolarity on mau 1 of port 1 on a
CoreBuilder 5000 10BASE-T SwitchModule in slot 1:

slot.port.mau
slot.port.mau Identifies the MAU for this operation.
slot (1 through 17) is the slot number and port (1 through 24) is the
port number. Use 1 for the mau variable. For example, to identify a
MAU on port 4 on the module in slot 6, enter

slot.
all
Specifies that all MAUs in the slot are affected by this operation.
disable
Disables autopolarity.
enable
Enables autopolarity. Autopolarity enables the MAU to automatically
switch the polarity of twisted-pair cabling. If, for instance, you
erroneously reverse the polarity of some twisted-pair cabling while
assembling it, autopolarity enables you to automatically detect this
problem and reverse the polarity.
