NETGEAR 8800 User Manual If you run diagnostics on an MSM/MM, that module is taken offline while the diagnostics test is performed. When the diagnostic test is complete, the MSM/MM reboots and becomes operational again. If you run diagnostics on the primary MSM/MM, the backup MSM/MM assumes the role of the primary and takes over switch operation. After the MSM/MM completes the diagnostic routine and reboots, you can initiate failover from the new primary MSM/MM to the original primary MSM/MM. Before initiating failover, confirm that both MSMs/MMs are synchronized using the show switch command. If the MSMs/MMs are synchronized, initiate failover using the run msm-failover command. For more detailed information about system redundancy and MSM/MM failover, see Understanding System Redundancy on page 64. Run diagnostics on one MSM/MM at a time. After you run the diagnostic routine on the first MSM/MM, use the show switch command to confirm that both MSMs/MMs are up, running, and synchronized before running diagnostics on the second MSM/MM. After the switch runs the diagnostic routine, test results are saved in the module's EEPROM and messages are logged to the syslog. To run diagnostics on I/O or MSM/MM modules, use the following command: run diagnostics [extended | normal | stack-port] {slot [ | A | B]} Where the following is true: • extended-Takes the switch fabric and ports offline and performs extensive ASIC, ASIC-memory, and packet loopback tests. Extended diagnostic tests take a maximum of 15 minutes. The CPU is not tested. Console access is available during extended diagnostics. If you have a Power over Ethernet (PoE) module installed, the switch also performs an extended PoE test, which tests the functionality of the inline power adapter. • normal-Takes the switch fabric and ports offline and performs a simple ASIC and packet loopback test on all ports. • -Specifies the slot number of an I/O module. When the diagnostic test is complete, the system attempts to bring the I/O module back online. Note: To run diagnostics on the management portion of the master MSM, specify slot A or B. If an I/O subsystem is present on the MSM, then that I/O subsystem will be non-operational until diagnostics are completed. • A | B-Specifies the slot letter of the primary MSM. The diagnostic routine is performed when the system reboots. Both switch fabric and management ports are taken offline during diagnostics. Before running diagnostics on a module, you can use the disable slot {offline} command to force the module to enter the offline state which takes the switch fabric and ports offline. If you run diagnostics on a module that is not offline, the switch automatically takes 198 | Chapter 8. Status Monitoring and Statistics
