Unsetting the Boot Parameter Using IOS Command Line Interface
ProcedureEffective with Cisco IOS-XE 3.2.3SQ, platform environment variables such as BootParam can be modified from the IOS Command Line Interface. This procedure can be performed using Telnet or Management IP, which is a convenient way to modify the variables.
The following are the boot parameter variables available:
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.
What to Do NextThe following is the example of the show platform environment variables command, if boot parameter variables are set.
PS1="rommon ! >" SupportedFeatures="1" SkipDiagsAlways="1" CodeSignDisable="1" BootParam1="ip=:::va: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=""
The following is the example of the show platform environment variables command if boot parameter variables are unset.
PS1="rommon ! >" SupportedFeatures="1" SkipDiagsAlways="1" CodeSignDisable="1" 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=""
This procedure unsets the boot parameter on a single Supervisor Engine 7-E card. So repeat this procedure on the other Supervisor Engine 7-E card.
