Saving Configuration Changes
Save any changes you make by using the
.W
command. This updates the database
immediately, and the screen refreshes, displaying the new values. Sometimes, how-
ever, you must reset the unit, or cycle the port for the changes to take affect (see
“Changes that Require Cycling or Resetting” on this page).
If you make changes to a screen, and try to leave it without saving, the screen warns
you “
Data has been modified. Write or Cancel changes
.” Press
.W
or
.C
to remove the warning and return to the screen.
Note
Sometimes the Write and Cancel commands do not appear in the list of commands (at
the bottom of screen) unless you make a change to a field.
Understanding the Configuration Database
Default configuration settings are stored in a non-volatile configuration database on the
SkyWay. When the unit is started or reset, the configuration database is loaded and
determines the runtime characteristics of each port.
The SkyWay allows you to make configuration changes to the Ethernet and RF ports
without disrupting operations. The changes are stored in the configuration database,
allowing you to change Skyway’s runtime port characteristics without resetting the unit,
by ‘cycling’ the port. This allows you to make minor changes on a port by port basis
without affecting operations on the other ports. This is very important on a base station
supporting many sub stations, where you need to avoid breaking the communications
link between the base station and any sub station.
Changes that Require Cycling or Resetting
You must cycle the port for the changes to take affect immediately if you edit any port
level configuration parameters (for example, those in the 1.2 menu tree).
To cycle the port: 1.
Go to 2.2.1 Generic Port Status and Control.
2.
Type 3 (or .N until the port number is the one you want).
3.
Set the Administrative Status Administrative Status Administrative Status Administrative Status field to Cycle.
4.
Type
.W
Cycle evacuates the port, reinstalls the driver, reads the database, and brings up the
port.
Resetting the Unit
You must reset the unit if you download an update to the SkyWay software using the
file transfer utilities, or if you change any global parameter, such as:
• enabling or disabling bridging
• enabling or disabling routing
