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

    Currently the router:
    sho ver

    ROM: System Bootstrap, Version 12.2(8r) [cmong 8r], RELEASE SOFTWARE (fc1)

    bob uptime is 25 weeks, 1 day, 23 hours, 55 minutes
    System returned to ROM by power-on
    System image file is "flash:c2600-ipbase-mz.123-6c.bin"

    no service password-encryption
    !
    hostname bob
    !
    boot-start-marker
    boot-end-marker
    !

    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 ;)

    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

    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
