Parameter Description
loadSharing Enables or disables load sharing. Enter -1, 0, or 1. These values control load
sharing as follows:
• -1 unconditionally disables load sharing, regardless of switch plane status

• 1 enables load sharing
If you do not want to change the setting, enter the value that corresponds to the
current setting displayed with the dspxbarmgmt command.
autoShutdown Enables or disables the Auto Shutdown feature. Enter 0 to disable this feature,
or enter 1 to automatically shut down a failed link between a switch plane and
a card slot.
If you do not want to change the setting, enter the value that corresponds to the

planeAlarmThresh Defines when a switch plane should be reported as bad. Set the threshold to the
number of failed links (between a switch plane and the card slots it services)
that exceeds your acceptable limit. The default threshold is 3. The PXM45 card
supports up to 14 links.
