4507R ios boot up

[eiregobragh]

Guy,
I'm installing a number of new 4507Rs and I've loaded the latest IOS onto the Bootflash.

So now on the bootflash is the ipbase IOS and the entservices IOS.

confreg = 2101

I configured the command:

boot system flash cat4500e-entservicesk9.mz.122-53.SG1.bin

but when I reload the chassis the Switch keeps loading the ipbase IOS.

Is there any reason for this?

Thanks,

Paul

You try confreg 0x2102? 0x2101 is likely ignoring the boot command.

You may want to verify the flash image too:
verify flash:cat4500e-entservicesk9.mz.122-53.SG1.bin

What does show boot output if that doesn't work?

Hi NetRx,
I tried changing the confreg to 0x2102 and it goes into ROMMON mode.

I'll try the verify command when I'm back at work on monday

Thanks,

The image might be on bootflash. Try removing any existing 'boot' commands and then replacing it with:

Switch#show bootflash
Switch#conf t
Switch(config)#no boot system flash:cat4500e-entservicesk9.mz.122-53.SG1.bin
Switch(config)#boot system flash bootflash:cat4500e-entservicesk9.mz.122-53.SG1.bin
Switch(config)#config-register 0x2102
Switch(config)#end
Switch#show bootvar
Switch#write mem
Switch#reload

Keep the config-register at 0x2102.

No---the modular switches should be 2101, not like the fixed config switches that do not have a "bootflash"

http://www.cisco.com/en/US/products/hw/routers/ps133/products_tech_note09186a008022493f.shtml

It needs to boot bootstrap which tells it to boot bootflash. Your only mistake is

boot system flash

where it needs to be

boot system flash bootflash:blablabla

like NetRX says. But the config reg should be 0x2101, not 0x2102

Lads,
that's great, the old "boot system flash" did seem a bit odd as with the 4507R there is no flash as such but bootflash.

Thanks so much, I'm sure that's it. I'll let you know how I get on on monday.

Thanks again,

Well, most documentation I have seen always points to 0x2102. Reference the following

http://www.cisco.com/en/US/docs/swi...3ew/configuration/guide/supcfg.html#wp1021899

for the 4500. In particular table 3-3 and the paragraph below.

If we debug eirego's boot process:
0x2101 works because it parses the first file found in bootflash and ignores the boot system command. Assuming here that the IP base image is first.
0x2102 does not work because boot system flash points to an invalid location. IOS freaks out and dumps into rommon.

All of our production 4500s are some variant of 0x102 or 0x2102.

0x2101 loads the first image it finds in flash regardless of the boot statement you try to use.The old image is still in bootflash so thats the image it will find first and boot. If you do a "dir bootflash: the image that is on top is the one that will load with a 0x2101 register. 0x2102 will use the image you specify in the boot statement . If there is no flash card in the 4507 then it will be " boot system flash bootflash:<imagename> .
