You must specify a path to an FTP server with an anonymous
user account in order to successfully execute the
upgrade
command, or the Mesh Point returns the error:
[Error] file must be an FTP url, for example "ftp://ftp.server.com/path/to/gw.pkg"
To begin the basic upgrade process, use the upgrade
command to specify the location of the upgrade file and its
password:
# upgrade -f
<ftp://ftp.server.com/path/gw.version.pkg>
-p fortress -ramdisk y|n
CAUTION: If you
use -ramdisk y
to upgrade a Mesh Point
with insufficient RAM
to hold the necessary
temporary images, the
upgrade will fail.
In order to speed the upgrade process, the ES2440 Mesh Point
defaults to using RAM (Random Access Memory) to hold the
temporary image files used during upgrades. Because the
ES520, ES820 and ES210 have less RAM, they default to
using internal flash memory to hold these images. You can
change this aspect of the upgrade process with the
-ramdisk
switch: y (yes) to use RAM, n (no) to use flash memory.
NOTE: Do not use
-ratelimit or
-noresume for locally
stored upgrade files
(with the
-e switch,
described below).
Optionally, you can throttle the download transfer rate for
upgrade files stored on an FTP server by specifying an upper
-ratelimit in whole megabits per second (Mbits/s), 1100.
To ensure that you are starting fresh with a new download, you
can also direct the Mesh Point to refrain from attempting to
resume partial downloads of an upgrade file with the
-noresume switch, which takes no arguments. If no previously
initiated partial download is detected, the upgrade function
ignores the
-noresume switch.
# upgrade -f
<ftp://ftp.server.com/path/gw.version.pkg>
-p fortress -ratelimit 1–100 -noresume
The Mesh Point CLI displays the status of the upgrade
process, which can take several minutes.
After the upgrade has completed, you must reboot the Mesh
Point, as described in Section 5.2.
If you experience problems after the Mesh Point reboots, revert
to the previously running Mesh Point software version (as
described in Section 5.2.1), and then retry the upgrade.
There are two additional upgrade options exclusively for use in
conjunction with the Mesh Point’s Auto-Config function:
# upgrade -d -f
<ftp://ftp.server.com/path/gw.version.pkg>
-p fortress -ratelimit 1–100 -noresume
The -d switch permits you to store the upgrade file (for
distribution and later use), without upgrading the Mesh Point’s
current software version.
