Bypassing start up config on C6500 sup720-3B

Question

hi,
I need to bypass startup config on sup720-3B supervisor card
I went to rommon mode
and put confreg 0x2142 and reset
The 6500 reboot
but I enter startup config again and again...and not the setup menu
see the log :
(s72033_sp-IPSERVICES_WAN-VM), Version 12.2(33)SXI4a, RELEASE SOFTWARE (fc2)
System Bootstrap, Version 12.2(17r)SX7, RELEASE SOFTWARE (fc1)
*Jul 20 13:40:30.588: %VS_PARSE-4-CONFIG_WARNING: Switch bootup in Standalone mode since config register sets to skip Startup config: 0x2142
*Jul 20 13:40:31.152: %PFREDUN-6-ACTIVE: Initializing as ACTIVE processor for this switch
config-register is set to 0x2142
Thanx in advance for your answers

Answer 1

You can bypass the start-up config on the 6500 with the following proceedure:
- reload the switch with a console access to the supervisor.
(on the console you would see the supervisor loading the image and booting the sup)
- wait until you see the log "%OIR-6-CONSOLE: Changing console ownership to route processor"
- Press CTRL + BREAK when you se the above log message.
- you will fall into the RP's rommon.
- here you need to change the config register to 0x2142. >> use the command: confreg 0x2142
- enter "reset" and wait until the supervisor boots up completely.
After it boots up completely you should see setup menu...
Hope this helps.
