Checking the Running Configuration Settings

To check the value of the settings you have entered, enter the show running-config command at the Router#
prompt:
router# show running-config
To review the changes you make to the configuration, use the EXEC mode show startup-config command
to see the changes and copy run-start stored in NVRAM.
The ROMMON variable is set from factory to boot the IOS as -"BOOT=bootflash:Image/packages.conf".
However, the boot command is not pre-configured.
As the boot command is not configured, the router boots to ROMMON mode after the first power cycle, and
the following message is displayed:
no valid BOOT image found
Final autoboot attempt from default boot device...
Located tracelogs.030
Image size 6181 inode num 13, bks cnt 2 blk size 8*512
Boot image size = 6181 (0x1825) bytes
Unknown image structure
boot: cannot determine first file name on device "bootflash:/"
rommon1>
To avoid the router booting into ROMMON state, it is highly recommended that you set the boot command
prior to the first reload.
router(config)# boot system flash bootflash:/Image/asr903rsp1-universalk9.x.x.x.-ext.bin
