9.5.1 Firmware update via web interface
To update firmware on devices in a cluster through web interface, open
«Cluster Firmware Upgrade»
tab of an
access point. When updating firmware of devices in a cluster, the firmware file will be loaded to each access point
and set to
«Primary Image»
. Reloading of the devices with new firmware version loading is performed
automatically. The previous firmware version will be saved as
«Secondary Image»
(backup firmware version).
Perform the following in
«Cluster Firmware Upgrade»
tab:
•
Upload Method
– select the firmware loading method for the devices. The loading through TFTP is used in
the example:
•
Image Filename
– enter a file name of firmware which will be loaded to the device.
•
Server IP
– enter an IP address of TFTP server on which firmware file is saved. «192.168.15.92» is used in
the given example.
Click
«Start-Upgrade»
to start updating. While firmware updating, do not switch off the devices and do not update
or change the web page with progress bar.
9.5.2 Firmware updating through DHCP Autoprovisioning
To update firmware, you need a TFTP server and a DHCP server with particular configuration. The updating
process is as follows:
1. An access point is loaded and obtains address via DHCP. The access point obtains 2 parameters from the
server while DHCP session: tftp-server and file name, where tftp-server – an IP address of TFTP server, and
filename is a name of the file with .manifest extension which contains data on the firmware.
2. A master of the cluster, according to received data, starts make attempts to download manifest-file from
TFTP server. After downloading the file, the master compares firmware version specified in a file with its
own. If firmware versions are different, the master downloads firmware file from the TFTP server (file name
of the firmware is specified in manifest-file) and updates automatically.
3. The other devices in the cluster define that the master is not in operation. Then, new master is selected in
the cluster. The device with bigger «uptime» value becomes a master. New master also repeat the second
step: downloads manifest-file, compares firmware versions and updates.
4. The cycle is repeated until all the devices in the cluster are updated.
Update configuration algorithm:
a) Place
"wop2.manifest"
file on TFTP server, the file should contain the following string:
VERSION= "1.16.0.X"
WOP-2ac-1.16.0.X.tar.gz
,
where WOP-2ac-1.16.0.X.tar.gz – name of the archive containing firmware for WOP-2ac;
1.16.0.X – a firmware version included to the archive. The firmware version might be viewed in «version» file in
firmware archive.
b) Place archive with firmware for WOP-2ac on TFTP server.
