Core issue
When the manual boot feature is enabled, it interrupts the boot sequence and puts the switch at a switch: prompt.
Resolution
To completely boot the switch, issue the boot command.
For the switch to boot automatically, the manual boot feature must be disabled. To disable the feature, perform these steps:
- To verify the current setting, issue the show boot command at the EXEC prompt or the set command at the switch: prompt.
These are examples of the output from these commands:
Switch#show boot
BOOT path-list: flash:c2900XL-h-mz-112.8-SA5.bin
Config file: flash:config.text
Enable Break: no
Manual Boot: yes
HELPER path-list:
NVRAM/Config file
buffer size: 32768
switch:set
BOOT=flash:c2900XL-h-mz-112.8-SA5.bin
MANUAL_BOOT=yes
- To set the switch to boot automatically, issue the no boot manual global configuration command.
- Return to the EXEC prompt and issue the write memory command to save the configuration, as shown in this example:
Switch(config)#no boot manual
Switch(config)#end
Switch#
Switch#write memory
Building configuration...
[OK]
- Alternatively, the configuration can be changed at the switch: prompt. Issue the MANUAL_BOOT=no command, which is case sensitive.
Note: The boot command must be issued to boot the switch the first time after the MANUAL_BOOT=no command has been issued.
This is an example:
switch: set
BOOT=flash:c2900XL-h-mz-112.8-SA5.bin
ENABLE_BREAK=yes
MANUAL_BOOT=yes
switch: MANUAL_BOOT=no
switch: boot
Loading "flash:c2900XL-h-mz-112.8-SA5.bin"...
- To verify the boot parameters, issue the show boot command again, as shown in this example:
Switch#show boot
BOOT path-list: flash:c2900XL-h-mz-112.8-SA5.bin
Config file: flash:config.text
Enable Break: no
Manual Boot: no
HELPER path-list:
..
Switch#
