Cisco Systems VG204 Manual De Usuario

The virtual configuration register is in nonvolatile RAM (NVRAM) and has the same functionality as 
other Cisco voice gateways. You can view or modify the virtual configuration register from either the 
ROM monitor or the operating system software. Within the ROM monitor, you can change the 
configuration register by entering the register value in hexadecimal format, or by allowing the ROM 
monitor to prompt you for the setting of each bit.

To change the virtual configuration register from the ROM monitor manually, enter the confreg 
command followed by the new value of the register in hexadecimal format, as shown in the following 
example:

rommon 1 > confreg 0x2101

You must reset or power cycle for new config to take effect

rommon 2 >

The value is always interpreted as hexadecimal. The new virtual configuration register value is written 
into NVRAM but does not take effect until you reset or reboot the voice gateway.

Entering the confreg command without an argument displays the contents of the virtual configuration 
register and a prompt to alter the contents by describing the meaning of each bit.

In either case, the new virtual configuration register value is written into NVRAM but does not take 
effect until you reset or reboot the voice gateway.

The following display shows an example of entering the confreg command:

rommon 7> confreg
