subinterfaces, or in the case of hardware failure.

or reload the chassis. Some problems may have no workaround.
Further Problem Description: This fix will effectively remove the possibility of a
SW_INIT_TIMEOUT.

VRRP is configured to track an existing tracking object.
The existing tracking object is removed from the global tracking configuration.
