Also, in case this matters:

#show fabric switching-mode
Global switching mode is Compact
dCEF mode is not enforced for system to operate
Fabric module is not  required for system to operate
Modules are allowed to operate in bus mode
Truncated mode is allowed, due to presence of CEF720, Standby supervisor module

Module Slot     Switching Mode

    3                 Crossbar
    4                 Crossbar
    5                 Crossbar
