Managing System Files
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
ecs-runtime.bix (using upper case and lower case letters exactly as
indicated here). Enter the file name for other switches described in this
manual exactly as shown on the web interface.
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
ECS-RUNTiIME.BIX from the server even though ecs-runtime.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, ecs-runtime.bix
and ECS-RUNTIME.BIX are considered to be unique files. Thus, if the
upgrade file is stored as ECS-RUNTIME.BIX (or even Ecs-runtime.bix)
on a case-sensitive server, then the switch (requesting ecs-runtime.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.
