13 Diagnostic tests not supported by M-EOS 9.6.2 and FOS 6.0 The command only prompts you to continue. switch:admin> supportsave -c This command will collect RASLOG, TRACE, supportShow, core file, FFDC data and other support information and then transfer them to a FTP/SCP server or a USB device. This operation can take several minutes. NOTE: supportSave will transfer existing trace dump file first, then automatically generate and transfer latest one. There will be two trace dump files transfered after this command. OK to proceed? (yes, y, no, n): [no] y Diagnostic tests not supported by M-EOS 9.6.2 and FOS 6.0 The diagnostic tests portTest and spinFab are designed to work between two Brocade-attached switches. These diagnostics will fail if the B-series switch is linked to an M-series switch. 116 Fabric OS Troubleshooting and Diagnostics Guide 53-1001187-01
