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 ECS4120-Series.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 ECS4120-Series.BIX from
the server even though ECS4120-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, ecs4120-
series.bix and ECS4120-Series.BIX are considered to be unique files. Thus, if the
upgrade file is stored as ECS4120-Series.BIX (or even ECS4120-series.bix) on a
case-sensitive server, then the switch (requesting ECS4120-serieS.bix) will not be
upgraded because the server does not recognize the requested file name and
