Parameters
show-number: Specifies the number of deadloops to display, in the range of 1 to 20.
offset: Specifies the offset between the starting deadloop and the latest deadloop, in the range of 0 to 19.
The default value is 0.
verbose: Displays detailed information. Without this keyword, the command displays brief information.
slot slot-number: Specifies an MPU by its slot number. Without this option, the command displays kernel
thread deadloop information for the active MPU. (In standalone mode.)
chassis chassis-number slot slot-number: Specifies an MPU on an IRF member device. Without this option,
the command displays kernel thread deadloop information for the global active MPU. (In IRF mode.)
