C9000 Series Syntax Parameters diag {stack-unit unit-number} [alllevels | level0 | level1 | level2] [interactive] [testname name] [terminate] stack-unit unitnumber alllevels level0 level1 level2 interactive Enter the stack-unit value to run offline diagnostic test on a specified stackunit. The stack-unit range is 0 to 7. Enter the keyword all levels to run the complete set of offline diagnostic tests. Enter the keyword level0 to run Level 0 diagnostics. Level 0 diagnostics check for the presence of various components and perform essential path verifications. In addition, they verify the identification registers of the components on the board. Enter the keyword Level1 to run Level 1 diagnostics. Level 1 diagnostics is a smaller set of diagnostic tests with support for automatic partitioning. They perform status/self test for all the components on the board and test their registers for appropriate values. In addition, they perform extensive tests on memory devices (for example, SDRAM, flash, NVRAM, EEPROM, and CPLD) wherever possible. At this level, ports are shut down automatically. Enter the keyword level2 to run Level 2 diagnostics. Level 2 diagnostics are a full set of diagnostic tests with no support for automatic partitioning. Level 2 diagnostics are used primarily for on-board loopback tests and more extensive component diagnostics. Various components on the board are put into Loopback mode and test packets are transmitted through those components. These diagnostics also perform snake tests using VLAN configurations. Enter the keyword interactive to run offline diagnostics in interactive mode. NOTE: On a C1048P, interactive diagnostic tests are supported only in standalone mode; they are not supported in stacking mode. testname name terminate Enter the testname name parameters to run a specified offline diagnostic test. Enclose the test-case name in double quotes (" "). For example: diag level1 testname "first". Enter the keyword terminate to stop the offline diagnostic tests that are running. Defaults All offline diagnostic tests are run on all switch CPUs (Control Processor, Route Processor, and line cards). Command Modes EXEC Privilege Usage Information Before you use this command to run diagnostic test, make sure that the port extender (PE) stack-unit is offline (offline stack-unitunit number command). You are prompted to reboot when the offline diagnostics is complete. 1258 PE Console Commands
