In the question below, I assigned a decimal value. 2102=0x836. So, in essence, I actually ran the command: > > router(config)#config-register 0x836 Actually, the correct answer is "it depends" :-) One of the quirky things about the IOS that you have to get used to, is how things change over time. What is a problem in one version of IOS, later gets fixed in another version of IOS. In earlier versions of code, there was a definite problem (converting a decimal value to an expected hex value). Cisco modified the command line parser somewhere around the tail end of 11.3 or 12.x code to remove that quirky little feature. Here is an output from a Cisco 804 running 12.03T1 code: cisco804(config)#config-register ? <0x0-0xFFFFFFFF> Config register number cisco804(config)#config-register 2102 ^ % Invalid input detected at '^' marker.
