When in rommon do you just type boot or do you have to tell it where the image is ?

Once thing to try is to set confreg in rommon mode.

Re: When reloading router it goes in RMON mode

I seem to remember that some platforms would boot to rommon if there was not a boot statement in IOS. I can't recall if the 7600 was one of these devices.

If you don't have 'boot system flash ' make sure you have that there.

Re: When reloading router it goes in RMON mode

Hi All,

From this perspective i see there is issue with the conf register due to which the router is going to Rommon mode after the reload of the device.

I request you to please check the following:-

Complete these steps:

In global configuration mode, issue the config-register 0x2102 command, and set the configuration register to 0x2102 for both the RP and the SP.

6500_IOS# config t

Enter configuration commands, one per line. End with CNTL/Z.

6500_IOS(config)# config-register 0x2102

6500_IOS(config)# end

To verify the configuration register value at the next reload, issue the show bootvar command.

6500_IOS# show bootvar

BOOT variable = slot0:c6sup12-ps-mz.121-13.E14,1

CONFIG_FILE variable =

BOOTLDR variable =

Configuration register is 0x2102

To verify that the configuration register on the SP also changed, issue the remote command switch show bootvar command.

6500_IOS# remote command switch show bootvar

6500_IOS-sp#

BOOT variable = slot0:c6sup12-ps-mz.121-13.E14,1

CONFIG_FILE variable =

BOOTLDR variable =

Configuration register is 0x2 (will be 0x2102 at next reload)

Reload the switch for the new SP configuration register setting to take effect.

6500_IOS# reload

Note: You can issue the copy running-config startup-config command at this point to save the configuration. However, this step is not necessary because the configuration register setting is not part of the startup or running configuration.

I hope this should solve your issue.As i am 100 % confident on this.

Plz rate if this help.

Regards

Inayath.
