[Soybomb]

Hey guys tomorrow I'm going to update the IOS on a neglected 2620XM and wanted to be sure I had process down.

My plan:
copy tftp flash blah blah blah
verfiy flash:c2600-ipbase-mz.123-6c.bin (and verify md5)
conf t
!
boot system flash flash:c2600-ipbase-mz.123-22.bin
boot system flash flash: c2600-ipbase-mz.123-6c.bin
!
end
!
write
reload

This should give me both IOS's in flash and will fall back to the older one if the new one fails to load. Look right?

you really only need the 123-22.bin boot system flash command. if this file fails, it will find an alternate image file in flash and load it instead. it really doesnt hurt by having both in there though.

ios also verifys the bin after transfer, just to make it was successful. like the dual boot command, the verify cant hurt either

Cool, thanks! Just didn't want to botch something up and wind up starting at rommon

 

[Soybomb]

Whats actually the proper syntax for the boot commands, if any. I've seen people use:
boot system flash flash:file.bin
boot system flash:file.bin
boot system flash file.bin
and a few other ways

 

[jlazzaro]

officially, it's boot system flash [device:][filename]

boot system flash [filename] will work though.

boot system flash:[filename] will not work.

guys keep in mind that this is for routers only.
For switches you actually need the colon
boot system flash:fileName

According to jlazzaro that syntax will not work, but you're saying thats whats necessary for switches?

It won't matter on my 2620, but its something good to know.

Thanks guys
