%sys-4-config_newer:

[Wavy Davy]

Hi,

On bootup on my 2503 I get a meesage: %SYS-4-CONFIG_NEWER: Configurations from version 12.2 may not be correctly understood.

Any ideas why? On the Cisco site it states:
Explanation "The software has detected that the configuration saved in memory was written by a newer version of software. There might be commands saved in memory that are not implemented by the older software version."

What does it mean "saved in memory", which memory?- the NVRAM I guess. Am I right in assuming that a command in the NVRAM is not supported by the IOS? The culprit command is:

ip kerberos source-interface any

However ip kerberos is supported by my IOS (I guess so because I can access ip kerberos commands in the config mode), so I am not sure why the command is not supported. Any feedback would be appreciated.....

I have seen that message alot since beginning to move over to 12.x IOS, but haven't seen any ill effects from it.

Hi Retired

The Cisco page said more or less the same- it has no detrimental effect. I would just like to know why, that's all.

Cheers for the input,

Would you post the boot sequence?  I've seen stuff like that happen when a boot loader trys to parse the config and encounters something it doesn't support, but I don't know on which platforms it does this.  Usually when this happens there will be a line in the boot output that says something to the effect of "The above messages are generated by the boot loader."  I'd like to see if this is whats happening.

I hope this is what you wanted. ip kerberos source-interface any seems to be the problem, but like I stated before, the command is supported by my IOS.

I've not seen it happen quite like that.  I've also not run 12.2 code anywhere yet.  As long as it works....
