    I read about specifying options in dhcp server so that my 4506 switch can
    obtain config file from tftp server. Is this a common practice? Is is
    better to save the config to flash and back it up manually on a tftp server
    or have it boot and get the config file from tftpserver?

    Bad practice... dunno 'bout common.
    Save it to nvram. Back it up on paper.

  5. That doesn't scale very well beyond maybe a handful of devices.

    "Save it to nvram" is definitely a must, but back it up via tftp or
    other means: for our switches and routers, we use tftp, while for our
    wireless access points a script (on the same system as the tftp server)
    runs to grab configurations from each access point's web interface;
    in either case, the "just backed-up" configuration for each device is
    compared to the last saved backup from that device, and any differences
    are sent to appropriate network admins for verification. That way we
    can verify that a change we made was indeed what we intended, and if an
    "unauthorized" change is made to a device, we can identify it immediately
    (well, within a day).

    The system that holds the configuration files is itself backed up to a
    tape unit (any removable backup media would suffice; we use tape), and
    we do have a "secondary" system that can be used to store and retrieve
    these configuration files if necessary.

    I hope this provides some useful ideas ....
