Using Conditional Variables In Templates; Using Substitution Variables In Templates - Dell PowerConnect W-Airwave User Manual

Using Conditional Variables in Templates

Conditional variables allow lines in the template to be applied only to access points where the enclosed
commands will be applicable and not to any other access points within the Group. For example, if a group of APs
consists of dual-radio Cisco 1200 devices (802.11a/b) and single-radio Cisco 1100 (802.11b) devices, it is
necessary to make commands related to the 802.11a device in the 1200 APs conditional. Conditional variables are
listed in the table below.
The syntax for conditional variables is as follows, and syntax components are described in
%if variable=value%

%endif%

Using Substitution Variables in Templates

Substitution variables are used to set AP-specific values on each AP in the group. It is obviously not desirable to
set the IP address, hostname, and channel to the same values on every AP within a Group. The variables in
90 are substituted with values specified on each access point's APs/Devices > Manage configuration page within
the AMP User page.
Sometimes, the running-config file on the AP does not include the command for one of these variables because
the value is set to the default. For example, when the "transmission power" is set to maximum (the default), the
line "power local maximum" will not appear in the AP running-config file, although it will appear in the startup-
config file. AMP would typically detect and flag this variance between the running-config file and startup-config
file as a configuration mismatch. To prevent AMP from reporting a configuration mismatch between the desired
startup-config file and the running-config file on the AP, AMP suppresses the lines in the desired configuration
when auditing the AP configuration (similar to the way AMP suppresses lines enclosed in parentheses, which is
explained below). A list of the default values that causes lines to be suppressed when reporting configuration
mismatches is shown in
