◆ 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 ECS4100-Series.BIX from
the server even though ECS4100-series.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,
ecs4100_series.bix and ECS4100_Series.BIX are considered to be unique files.
Thus, if the upgrade file is stored as ECS4100_Series.BIX (or even
Ecs4100_Series.bix) on a case-sensitive server, then the switch (requesting
ECS4100_Series.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.
To enable automatic upgrade, enter the following commands:
1. Specify the TFTP or FTP server to check for new operation code.
■
When specifying a TFTP server, the following syntax must be used, where
filedir indicates the path to the directory containing the new image:
tftp://192.168.0.1[/filedir]/
