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.

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)
