requested). However, keep in mind that the file systems of many
operating systems such as Unix and most Unix-like systems (FreeBSD,
NetBSD, OpenBSD, and most Linux distributions, etc.) are case-
sensitive, meaning that two files in the same directory, ms453490m.bix
and MS453490M.bix are considered to be unique files. Thus, if the
upgrade file is stored as MS453490M.bix (or even Ms453490m.bix) on
a case-sensitive server, then the switch (requesting ms453490m.bix)
will not be upgraded because the server does not recognize the
requested file name and the stored file name as being equal. A notable
exception in the list of case-sensitive Unix-like operating systems is
Mac OS X, which by default is case-insensitive. Please check the
documentation for your server’s operating system if you are unsure of
its file system’s behavior.
◆ Note that the switch itself does not distinguish between upper and
lower-case file names, and only checks to see if the file stored on the
server is more recent than the current runtime image.
◆ If two operation code image files are already stored on the switch’s file
system, then the non-startup image is deleted before the upgrade
image is transferred.
◆ The automatic upgrade process will take place in the background
without impeding normal operations (data switching, etc.) of the
switch.
◆ During the automatic search and transfer process, the administrator
cannot transfer or update another operation code image, configuration
file, public key, or HTTPS certificate (i.e., no other concurrent file
management operations are possible).
◆ The upgrade operation code image is set as the startup image after it
has been successfully written to the file system.
◆ The switch will send an SNMP trap and make a log entry upon all
upgrade successes and failures.
◆ The switch will immediately restart after the upgrade file is successfully
written to the file system and set as the startup image.
P ARAMETERS
The following parameters are displayed:
◆ Automatic Opcode Upgrade – Enables the switch to search for an
upgraded operation code file during the switch bootup process.
(Default: Disabled)
◆ Automatic Upgrade Location URL – Defines where the switch should
search for the operation code upgrade file. The last character of this
URL must be a forward slash (“/”). The ms453490m.bix filename must
not be included since it is automatically appended by the switch.
(Options: ftp, tftp)
