• The host portion of the upgrade file location URL must be a valid IPv4 IP address.
DNS host names are not recognized. Valid IP addresses consist of four numbers,
0 to 255, separated by periods.
• The path to the directory must also be defined. If the file is stored in the root
directory for the FTP/TFTP service, then use the “/” to indicate this (e.g.,
ftp://192.168.0.1/).
• The file name must not be included in the upgrade file location URL. The file name
of the code stored on the remote server must be FGL-2870-OP-V1.3.4.0.bix (using
upper case and lower case letters exactly as indicated here).
• The FTP connection is made with PASV mode enabled. PASV mode is needed to
traverse some fire walls, even if FTP traffic is not blocked. PASV mode cannot be
disabled.
• The switch-based search function is case-insensitive in that it will accept a file
name in upper or lower case (i.e., the switch will accept FGL-2870-OP-V1.3.4.0.bix
from the server even though FGL-2870-OP-V1.3.4.0.bix was 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,
FGL-2870-OP-V1.3.4.0.bix and FGL-2870-OP-V1.3.4.0.bix are considered to be
unique files. Thus, if the upgrade file is stored as FGL-2870-OP-V1.3.4.0.bix(or
even FGL-2870-OP-V1.3.4.0.bix) on a case-sensitive server, then the switch
(requesting FGL-2870-OP-V1.3.4.0.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.
• If the startup operation code file is named FGL-2870-OP-V1.3.4.0.bix, then the
upgrade image will be stored as op1.bix, and the next upgrade image as op2.bix.
• 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.
