Catalyst 4500 switch loses startup-config

[alanjwells]

I have a Catalyst 4503 switch. When I reset the switch it boots to new configuartion wizard.

I am writing the configuration to NVRAM using the wr mem command. I believe it may be to do with the config register:

Cat4503#sh bootvar

BOOT variable does not exist

CONFIG_FILE variable does not exist

BOOTLDR variable does not exist

Configuration register is 0x8101

You are right change it to 0x2101 or 0x2102 and you should be fine . 0x2102 will require a boot statement to boot correctly where 0x2101 will just find the first image in bootflash and load that .

Thanks.

Yep just did a restart and all good.

Cheers.
