TheControl Processor CPU ID is 0.pe Enter thepe pe-id parameters to display only the offlinediagnostic test available on the port extender (PE).stack-unit unit-numberEnter thestack-unit unit number parameters to displayonly the offline diagnostic test available on the specified stackunit. The range is from 0 to 7.linecard slot-id Enter the linecard slot-id parameters to display only theoffline diagnostic tests available for a specified line card. Therange of line-card CPU IDs is from 0 to 11. Each line-card CPUprocesses packets on the corresponding switch line card; forexample, line-card CPU 1 processes packets on line card 1.alllevels Enter the keyword alllevels to display the complete set ofoffline diagnostic tests.interactive Enter the keyword interactive to display interactive diagtestcases.level0 Enter the keyword level0 to display only the Level 0 diagnostictests. Level 0 diagnostics check for the presence of variouscomponents and perform essential path verifications. Inaddition, they verify the identification registers of thecomponents on the board.level1 Enter the keyword level1 to display only the Level 1 diagnostictests. Level 1 diagnostics is a smaller set of diagnostic tests withsupport for automatic partitioning. They perform status/self testfor all the components on the board and test their registers forappropriate values. In addition, they perform extensive tests onmemory devices (for example, SDRAM, flash, NVRAM, EEPROM,Debugging and Diagnostics 756
