Unsetting the Boot Parameter from ROMMON Using Console

This procedure provides instructions to unset the boot parameter variables from ROMMON using Supervisor Engine 7-E console.

The following are the boot parameter available:

  • BootParam1
  • BootParam2
  • BootParam3
  • BootParam4
  • BootMode
Important:

You must perform this procedure on both active and standby Supervisor Engine 7-E card because this procedure is applicable only for the active Supervisor Engine 7-E. Hence you need to repeat this procedure on the standby Supervisor Engine 7-E card as well.

Before You Begin
  • Ensure that you have access to the Cisco RF Gateway 10 Supervisor Engine 7-E Slot 1 and Slot 2 console ports.
  • Verify if the Cisco RF Gateway 10 IOS XE software image exists and is accessible.
    
    RFGW-10#dir bootflash:*.bin
    RFGW-10#dir slavebootflash:*.bin
    
    
    

    Note


    The Cisco RF Gateway 10 IOS XE software image can be loaded from bootflash: or remote server.
Procedure
    Step 1   Connect to Cisco RF Gateway 10 Supervisor Engine 7-E slot 1 and slot 2 through console.
    Step 2   enable
    Enables privileged EXEC mode.
    • Enter your password if prompted.


    Example:
    RFGW-10> enable
    
    
    Step 3   Verify if the boot parameter with ip=::::nova:eth0:off rw disableautoreboot is set.

    Example:
    RFGW-10# show platform environment variables 
    PS1="rommon ! >"
    SupportedFeatures="1"
    SkipDiagsAlways="1"
    CodeSignDisable="1"
    BootParam1="ip=::::nova:eth0:off rw disableautoreboot"
    BootParam2="BootMode=0"
    ConfigReg="0x2102"
    DiagMonitorAction="Normal"
    RommonVer="15.0(1r)SQ(315)"
    BOOT="slot0:rfgwk10-entservicesk9.03.03.01.SQ.150-2.SQB1.
    bin,12;bootflash:rfgwk10-entservicesk9.03.02.00.SQ.150-2.SQA.bin,12;"
    RET_2_RTS="01:07:15 EST Tue Feb 4 2014"
    BootedFileName="slot0:rfgwk10-entservicesk9.03.03.01.SQ.150-2.SQB1.bin"
    ReqClearAutoboot="1"
    BootStatus="Success"
    RET_2_RCALTS=""
    
    
    
    Step 4   Reload using the command reload

    Example:
     RFGW-10#  reload 
    
    
    Step 5   Press Ctrl-C on the Cisco RF Gateway 10 Supervisor Engine 7-E console to stop the boot process to enter ROMMON mode in console connection.

    Example:
    RFGW-10# Ctrl-C
    Restarting system.

    Step 6   Unset the boot parameter using the command unset bootparamvariable .
    • BootParamvariable - The boot parameter variables. The following are the boot Parameter variables available:
      • BootParam1
      • BootParam2
      • BootParam3
      • BootParam4
      • BootMode


    Example:
    rommon1> unset bootparam1
    rommon2>  unset bootparam2
    rommon3> unset bootparam3
    rommon4>  unset bootparam4
    
    
    
    Step 7   Boot the Cisco RF Gateway 10 IOS XE software image from the bootflash:

    Example:
    rommon5> boot bootflash:rfgwk10-entservicesk9.03.03.01.SQ.150-2.SQB1.bin
    
    Step 8   Repeat steps Step 2 to Step 7 on standby console.
    Step 9   Verify if the correct version of IOS is on both Supervisor Engine 7-E cards, they are in SSO Redundancy mode.
