4510 - doesnt boot goes straight in rommon mode

hi all,

 

i have another 4510 the other one wont let boot up in 2142 mode so i cant reset the password but this switch it has already been flattened :)

 

basically everytime i turn it off/on from the plugs or even enter the command #reset in Ios it starts in rommon mode and to boot up to Ios i need to enter in the #boot command and then it starts the Ios software

 

why is this, is this normal for it to go straight in rommon mode and to not auto boot into Ios

 

cheers,

rob

Hi,

No, that is not the correct behavior. The switch should boot directly to IOS every time you turn it off and then back on. Check your boot parameters to make sure it is set correctly. "show boot var" should show you the IOS you should boot from.

HTH

ok think i know what to do -

 

rommon#BOOT=

rommon#BOOT=bootflash:

rommon#sync

 

will that work?

 

or what about if i do when im in Ios

 

confreg 0x2102

copy run start

After the switch boots to IOS, try this command "sh boot" you should see something like this

 

BOOT variable = bootflash:<name of the IOS>

if you don't see the correct IOS, try setting the boot parameter using this command

boot system flash <name of the ios>

change the confreg to 0x2102, save config and reload.

Other to what Reza has posted, what happens if you change the config-registry value to 0x2101 and reboot?

i will close this post as now everytime it boots to Ios from rommon mode its asking for a bloody password so im back into trying to recover the password again using rommon mode 2142 which im having no luck at all

Ok, so you're trying to go into password recovery mode?
So in ROMmon, what happens if you rename the config file? Command: rename nvram:config.text nvram:config.text.bak

still not working when i set the boot flash to my Ios .bin file?

 

Switch#sh run | i boot

boot system flash cat4500e-universalk9.SPA.03.07.01.E.152-3.E1.bin
boot-end-marker

 

#boot system flash cat4500e-universalk9.SPA.03.07.01.E.152-3.E1.bin

#copy run start

You need the colon and boot

boot system bootflash:cat4500e-universalk9.SPA.03.07.01.E.152-3.E1.bin

**bleep** now i have two boots -

 

boot-start-marker
boot system flash cat4500e-universalk9.SPA.03.07.01.E.152-3.E1.bin
boot system bootflash:cat4500e-universalk9.SPA.03.07.01.E.152-3.E1.bin
boot-end-marker
Switch#

 

how do i get rid of the first one?
