3. In the 'Remote Configuration File URL' field, enter the URL address of the remote
server where the configuration file is located. The URL format is as follows:
protocol://server/filename.<conf/ini>, for example:
•
ftp://10.10.10.10/MP20x_<MAC>.conf
•
http://20.20.20.20/MP20x_<MAC>.ini
where <MAC> is replaced with the MAC address of MP-20x's WAN.
4. In the 'Check every' field, enter the time interval (in hours) for which MP-20x
periodically checks for a new configuration file. if 0 is defined, MP-20x checks only
once for a new configuration file, and this occurs after the system restarts.
5. Click the OK button. A download process begins. When downloading is completed, a
confirmation screen appears, asking you if you want to load the new version.
6. Click OK to confirm. The upgrade process begins and should take no longer than one
minute to complete. At the conclusion of the upgrade process, MP-20x automatically
reboots and the new software version runs.
If a new version is not available, click the Check Now button to perform an immediate
check (instead of waiting for the next scheduled one). The screen displays a green
"Check in progress..." message.

Version 3.0.1
For additional security, MP-20x can be configured to use HTTPS client-server
certification when connecting to a remote server (refer to 'Certificates' on page
210).
The configuration file can have one of the following two formats: a hierarchical
conf file (indicated by file extension .conf) or a flat ini file (indicated by file
extension .ini).
The parameter '/rmt_config/version' defines the version of the configuration file.
MP-20x uses the new configuration file only if the version that is defined in this
file is later than the current version. By default, the 'version' is set to 0. This
means that each time Service Providers' operations personnel require MP-20x
to download a new configuration file, they need to increment the 'version'
parameter in the new file (in the .conf file, the 'version' parameter is under the
section 'rmt_config'). To simplify the procedure, it is possible to use the current
date in YYYYMMDD format as the version field.
The remote configuration file must include only a subset of the complete
MP20x.conf file. A recommended procedure is to start with a MP-20x restored
to its factory settings, modify using the embedded Web server the parameters
that should appear in the remote configuration file, and then upload (save) the
configuration file. You must save only the modified parameters, as described in
'Remote Administration' on page 243.
The string <MAC> enables the ISP to pre-configure all its deployed MP-20xs
with the same URL and file details (under rmt_config/url) and still have each
MP-20x download its unique configuration file. Once the URL is configured with
the string <MAC>, MP-20x that is trying to update its configuration file
automatically replaces <MAC> with its own unique MAC address. For example,
if there's a MP-20x with a WAN MAC address 00:01:02:03:04:05, the ISP can
configure the url to http://myserver.com/my_conf_file_<MAC>.conf - and place
a file called 'my_conf_file_00_01_02_03_04_05.conf' on the server.
Downloading a configuration file from a remote server can also be performed
from the CLI:
1) Using Telnet, access MP-20x, and then enter the user name and password.
2) Enter the command rmt_config, for example:
rmt_config –u http://myserver.com/my_conf_file.conf
3) Enter rmt_config without any arguments for more help information.
