Config-Register question

I am running a 4506 Catalyst switch and CatOS. Here is the output of the show boot command.

OFF_4506_24 (enable) show boot

BOOT variable = bootflash:cat4000-k8.7-6-3.bin,1;

CONFIG_FILE variable = bootflash:switch.cfg

Configuration register is 0x2

ignore-config: disabled

auto-config: non-recurring

console baud: 9600

boot: image specified by the boot system commands

I put this into the Cisco Output interpreter tool and it says the configregister should be 0x10f but I thought it should be 0x2102. also I think the auto-config is wrong. Can explain why it should be 0x10f and not 0x2102? also if you see anything else wrong. We had a problem when we power cycled the switch, it would not boot up and work until we connected something to the console port. As soon as we did connect something it finished booting. Is the reason for this the Config-Register?

Thanks,

Mike

Re: Config-Register question

Hi Mike,

Configuration register value is 0x10F, which causes the switch to boot from what is specified by the BOOT environment variable.

Baud rate is set to 9600.

ignore-config parameter is disabled.

**Configuration register value is 0x2**, enables instantaneous break into rommon.. this is not advisable as it will push the switch in to the rommon mode..

0x0 (which tells it to go into rommon)

The recommended mode is 0x2102... 0x102 tells it to boot from flash first. Depends how you want it to boot, from flash first or from the boot variable first?

In your case Configuration register value is set to 0x2 instead of 0x2102.Please change the configuration register value to 0x2102 using ""set boot config-register ""

and reboot the switch.

It should resolve your issue.

Thanks,

Satish
