Config Register ...

[sanjaynadarajah]

[1] Can someone tell me the difference between the config register value of 0x2102 and 0x2102.

[2] Where to find the meaning of all the config-registers from Cisco Doc ?

Thank you,

Sanjay,

The below document should address questions around Config-registers.

I hope it helps.

Hi Sanjay,

The config register setting is used to change the router behavior in how to boot and options to used while booting like ignore configuration, disable boot messages

0x2102 - factory default settings for config reg

This tells the router should attempt to load a Cisco IOS? software image from Flash memory and load the startup configuration with a console speed of 9600 baud.

few main settings

0x2100 - ROM MONITOR

0x2101 - Boots in ROM

0x2142 - Password recovery; ignores NVRAM Config file

Hope this Helps

Thanks,

Raj
