Hi to all,
how to upgrade the rommon on a VSS with 4500X ?
- copy the rommon software to bootflash and sup-bootflash.
- reload and type ctrl-c for break sequence
- Configure the boot parameter in rommon mode .
boot cat4500-e-promupgrade-150_1r_SG2
Is this the way it works ? Or is this only for redundant supervisor engines in one chassis
Thanks in advance
Regards
Alex

Hi Inayath
thanks for the link, but for my understanding is this for switches in standalone mode or with redundant sups
But I am looking for a VSS upgrade.

Hi,
today I had the same question and found this unanswered discussion.
So here's what I did, it may help others:
#conf t (config)#no boot system (config)#boot system bootflash:cat4500-e-ios-promupgrade-150-1r-SG10 (config)#boot system bootflash:cat4500e-universalk9.SPA.03.06.02.E.152-2.E2.bin (config)#^Z #write #show bootvar BOOT variable = bootflash:cat4500-e-ios-promupgrade-150-1r-SG10,12;bootflash:cat4500e-universalk9.SPA.03.06.02.E.152-2.E2.bin,12; CONFIG_FILE variable does not exist BOOTLDR variable does not exist Configuration register is 0x2102 Standby BOOT variable = bootflash:cat4500-e-ios-promupgrade-150-1r-SG10,12;bootflash:cat4500e-universalk9.SPA.03.06.02.E.152-2.E2.bin,12; Standby CONFIG_FILE variable does not exist Standby BOOTLDR variable does not exist Standby Configuration register is 0x2102 #redundancy reload peer ! when the peer is online again #redundancy force-switchover #This will reload the active unit and force switchover to standby[confirm] ! when the entire system is up again #conf t (config)#no boot system bootflash:cat4500-e-ios-promupgrade-150-1r-SG10 (config)#^Z
Basically what you'd do for a 'normal' IOS-update, just with an additional entry for the promupgrade first in the boot loader.

Rolf,
Don't forget to remove the first boot variable string instructing to load the ROMmon after the process has been completed.

Thanks Leo, a valid point!
I wanted to keep this how-to sequence compact, but some additonal lines won't hurt :)

Hi! Thanks for your replies.
Can I also start Cat6500 Sup720 Rommon Upgrade from Rommon itself? I mean boot into rommon and start upgrade from there?
This could save some downtime. Thanks.
