Hello Ramu,
Can you try to figure out the use of 2922 on your own with below details:
The configuration register can be used to change Cisco router behavior in several ways, such as:
 | How the router boots (into ROM Monitor (ROMmon) or NetBoot). |
| Options while booting (ignore configuration, disable boot messages). |
| Console speed (baud rate for a terminal emulation session). |
Config Register # | 2 | 9 | 2 | 2 |
Bit Number | 15 14 13 12 | 11 10 9 8 | 7 6 5 4 | 3 2 1 0 |
Binary | 0 0 1 0 | 1 0 0 1 | 0 0 1 0 | 0 0 1 0 |
Bit Number | Hexadecimal | Meaning |
00 to 03 | 0x0000 to 0x000F | Boot field |
06 | 0x0040 | Causes system software to ignore NVRAM contents |
07 | 0x0080 | OEM bit enabled |
08 | 0x0100 | Break disabled |
09 | 0x0200 | Use secondary bootstrap |
10 | 0x0400 | IP broadcast with all zeros |
11 to 12 | 0x0800 to 0x1000 | Console line speed (default is 9600 baud) |
13 | 0x2000 | Boot default Flash software if network boot fails |
14 | 0x4000 | IP broadcasts do not have network numbers |
15 | 0x8000 | Enable diagnostic messages and ignore NVRAM contents |
5,11,12 | 0x0020, 0x0800, 0x1000 |
