Booting: Vector Error Occurs When Booting from Flash Memory
Booting: Vector Error Occurs When Booting from Flash Memory
Symptom: Vector errors occur when a user is booting a router from Flash memory.
Table 3-11 outlines the problems that might cause this symptom and describes solutions to those
problems.
Incorrect or corrupted image
(exec functions)
Step 1 Obtain the correct system image. If necessary, contact your
technical support representative to determine which image is
appropriate.
Step 2 Use the copy tftp flash privileged exec command to retrieve
the image.
Step 3 Check the configuration register using the show version exec
command. Set the register to boot from Flash memory. For
information about configuration register settings, refer to your
hardware installation and maintenance documentation.
Step 4 Use the show running-config privileged exec command to
determine whether the active configuration contains the
boot system flash global configuration command. Use the
show startup-config privileged exec command to determine
whether the boot system flash command is included in the
configuration stored in NVRAM.
