Windell,

What is your configuration register set to? There is a setting to prevent the switch from being reloaded via a VTY line.

Mark

Mark,

Configuration register is 0x2102

Make sure the SP conf. reg. is the same as the RP conf reg.

From the exec privilege prompt, do a "remote command switch sho bootvar" and make sure it is also set to 0x2102.

Thanks Victor!

It was set to 0x0, but how can i change it?

cor01-6506#remote command switch show bootvar

BOOT variable = bootflash:s72033-jk9sv-mz.122-17d.SXB6.bin,

CONFIG_FILE variable does not exist

BOOTLDR variable does not exist

Configuration register is 0x0

I got it!

both the RP and the SP are now set to 0x2102.

thanks again!

Windell:

Great!

Sorry, I just read your post now. Im glad you found out the command to use and fixed it.

Please rate all posts.

Regards

Victor

Ok Windell, but how did you got it?

I'm having the same exactly issue than you :(

It's a bit counter-intuitive to fix this.  You have again set the config register on the RP, which will then get propograted to the SP.

 

Router#reload

Router#remote command switch show bootvar

BOOT variable = s72033-adventerprisek9-mz.151-2.SY5.bin,1;
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x0

Router#conf t
Router(config)#config-register 0x2102
Router(config)#exit

Router#remote command switch show bootvar

BOOT variable = s72033-adventerprisek9-mz.151-2.SY5.bin,1;
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x0 (will be 0x2102 at next reload)

Router#reload

System configuration has been modified. Save? [yes/no]: yes
Building configuration...
[OK]
Proceed with reload? [confirm]

 

I just upgraded 2 4500 chassis and had the problem on the 2nd one.

Suprisingly, there's only 1 sup and the customer says it hasn't changed for years, and was rebooted since.

Anyways, the solution is to re-apply : config-register 0x2102

and reboot
