Automatic Installation of Operation Code and Configuration Settings
Downloading
Operation Code from
a File Server
Automatic Operation Code Upgrade can automatically download an operation
code file when a file newer than the currently installed one is discovered on the file
server. After the file is transferred from the server and successfully written to the file
system, it is automatically set as the startup file, and the switch is rebooted.
Usage Guidelines
◆ If this feature is enabled, the switch searches the defined URL once during the
bootup sequence.
◆ 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 ECS4620-28T.bix (using
lower case letters as indicated).
◆ 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 ECS4620-28T.BIX from
the server even though ECS4620-28T.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, ecs4620-28t.bix and
ECS4620-28T.BIX are considered to be unique files. Thus, if the upgrade file is
stored as ECS4620-28T.BIX (or even Ecs4620-28t.bix) on a case-sensitive server,
then the switch (requesting ECS4620-28T.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.
