5. Select the model AP from the drop-down list, and select Fetch.
6. W-AirWave automatically attempts to replace some values from the configuration of that AP with variables to
enable AP-specific options to be set on an AP-by-AP basis. Refer to "Using Template Syntax" on page 186
These variables are always encapsulated between % signs. On the right side of the configuration page is the
Additional Variables section. This section lists all available variables for your template. Variables that are in
use in a template are green, while variables that are not yet in use are black. Verify these substitutions to
ensure that all of the settings that you believe should be managed on an AP-by-AP basis are labeled as
variables in this fashion. If you believe that any AP-level settings are not marked correctly, please contact Dell
customer support at dell.com/support before proceeding.
7. Specify the device types for the template. The templates only apply to devices of the specified type.
n Specify whether W-AirWave should reboot the devices after a configuration push. If the Reboot Devices
after Configuration Changes option is selected, then W-AirWave instructs the AP to copy the
configuration from W-AirWave to the startup configuration file of the AP and reboot the AP.
n If the Reboot Devices after Configuration Changes option is not selected, then W-AirWave instructs
the AP to copy the configuration to the startup configuration file and then tell the AP to copy the startup
configuration file to the running configuration file.
n Use the reboot option when there are changes requiring reboot to take effect, for example, removing a
new SSID from a Cisco IOS device. Copying the configuration from startup configuration file to running
configuration file merges the two configurations and can cause undesired configuration lines to remain
active on the AP.
8. Restrict the template to apply only to the specified version of firmware. If the template should only apply to a
specific version of firmware, select Yes and enter the firmware version in the Template Firmware Version
text field.
9. Select Save and Apply to push the configuration to all of the devices in the group. If the devices are in
monitor-only mode (which is recommended while you are crafting changes to a template or creating a new
one), then W-AirWave will audit the devices and compare their current configuration to the one defined in the
template.
If you set the reboot flag to No, then some changes could result in configuration mismatches until the AP is rebooted.
For example, changing the SSID on Cisco IOS APs requires the AP to be rebooted. Two other settings that
require the AP to be rebooted for configuration change are Logging and NTP. A configuration mismatch
results if the AP is not rebooted.
If logging and NTP service are not required according to the Group configuration, but are enabled on the AP,
you would see a configuration file mismatch as follows if the AP is not rebooted:
