Cant Change Boot Variable

I successfully downloaded a new version of IOS to this 3750 switch, changed the boot system commands, yet the boot variable does not change, nor do the boot statements appear in the running config. I also did a 'wr mem'.

Anyone seen this before?

Thanks

nhv-c14-sw1#conf t

Enter configuration commands, one per line. End with CNTL/Z.

nhv-c14-sw1(config)#boot system flash:c3750-ipbasek9-mz.122-35.SE5.bin

nhv-c14-sw1(config)#boot system flash:c3750-i9-mz.121-19.EA1c

nhv-c14-sw1(config)#^Z

nhv-c14-sw1#

nhv-c14-sw1#sh boot

BOOT path-list : flash:c3750-i9-mz.121-19.EA1c

Config file : flash:/config.text

Private Config file : flash:/private-config.text

Enable Break : no

Manual Boot : no

HELPER path-list :

Auto upgrade : yes

nhv-c14-sw1#sh run | in boot

I don't have a 3750 to test with and i may be way off base but instead of entering separate "boot system flash.." commands could you just try to enter both images on the same line and separate them with a semicolon eg.

boot system flash:;

I believe you need to have them on the same line and because you are entering them separately it's not ignoring your new IOS it is just overwriting it in the config each time when you enter the second boot system flash string.

Re: Cant Change Boot Variable

Victor,

So you have both files available in flash? The IOS that is in the boot path-list is missing the .bin extension. I am assuming that your config register is 0x0 on the switch.

HTH,

Re: Cant Change Boot Variable

Now that I am thinking about it.. I don't believe the boot strings are shown in the running config. I remember reading somewhere about that. Just tested with a 3750 here and they are not in the running config either.

Mark:

You're right, though, the boot statements dont appear in the running config. YOu have to do a 'sh boot' to see the variable. Also, the reason why that file doesnt have a .bin extension on it is that it is a directory (compressed TAR file) with the .bin file inside of it.

Thanks, guys

Don't take it so badly, it was just a lucky guess :-)

Thanks for letting us know it worked.
