Hello All,

I need to upgrade IOS on 4509 switch with two Supervisor Engine 8-E. The memories are bootflash, slot0, slavebootflash, slaveslot0. Let take below promupgrade and image.

promupgrade : cat4500-e-ios-promupgrade-151-1r-SG5

image : cat4500es8-universalk9.SPA.03.06.02.E.152-2.E2.bin

Please help me to create boot sequence. I made myself one which is given below. Please check and advise me.

boot system flash bootflash:cat4500-e-ios-promupgrade-151-1r-SG5 (new promupgrade )

boot system flash bootflash:cat4500es8-universalk9.SPA.03.06.02.E.152-2.E2.bin(new image)

boot system flash slot0:cat4500-e-ios-promupgrade-151-1r-SG5 (new promupgrade )

boot system flash slot0:cat4500es8-universalk9.SPA.03.06.02.E.152-2.E2.bin(new image)

boot system flash slavebootflash:cat4500-e-ios-promupgrade-151-1r-SG5 (new promupgrade )

boot system flash slavebootflash:cat4500es8-universalk9.SPA.03.06.02.E.152-2.E2.bin(new image)

boot system flash bootflash:OLD IMAGE

boot system flash slot0:OLD IMAGE

boot system flash slavebootflash:OLD IMAGE

boot system flash slavebootflash:OLD IMAGE

Is this correct ?

Is it necessary to give promoupgrade on all memory location initially like i did above ?

Do i need to remove promoupgrade boot sequence after ios upgradation ?

Regards,

Abhijith

Hi,

As long as you have the same exact IOS installed in both sups and redundancy is configured correctly, you only need this command on the primary sup.

boot system flash bootflash:cat4500es8-universalk9.SPA.03.06.02.E.152-2.E2.bin
