Indicates what happens when you do a reset on the switch fabric module
when autoMap is enabled.

Important Consideration
■
After you enable or disable a module for automatic backplane
trunking, the switch fabric module verifies that the interface module’s
backplane configuration is compatible or not compatible to the switch
fabric’s configuration.
■
If autoMap is enabled on the desired interface module, then the
switch fabric module verifies that the switch fabric and interface
module’s backplane configuration satisfies the requirements of
automatic backplane trunking. If the switch fabric module and
interface module satisfy requirements, then no reset is required. If
not, then the switch fabric module determines if the interface
module must reconfigure to support backplane configuration
requirements. If the switch fabric module or interface module must
reconfigure, then a message is sent to the user that a reset is
required:
Fabric reset required for trunk configuration to be
effective for the module in slot x.
■
If autoMap is disabled, the switch fabric module verifies that the
interface module’s backplane configuration is compatible to the
switch fabric’s configuration. If the interface module is compatible
to the switch fabric module’s backplane configuration, then no
reset is required. If not, then the switch fabric module determines if
the interface module can support the defined switch fabric
module’s backplane configuration.
If the interface module can, then a message is sent to the interface
module with the desired backplane port configuration. Otherwise,
the switch fabric module will modify its configuration and a
message is sent to the user that a reset is required:
Fabric reset required for trunk configuration to be
effective for the module in slot x.
