Managing System Files

•
FTP (port 21) and TFTP (port 69) are both supported. Note that the
TCP/UDP port bindings cannot be modified to support servers listening
on non-standard ports.
•
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 SSE-
G2252-SERIES.BIX (using 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
SSE-G2252-SERIES.BIX from the server even though SSE-G2252-
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, sse -
G2252-series.bix and SSE-G2252-series.bix are considered to be
unique files. Thus, if the upgrade file is stored as sse-G2252-series.bix
(or even SSE-g2252-series.bix ) on a case-sensitive server, then the
switch (requesting SSE-G2252-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).
