Wireless Access

This is a really cool addtion to the process - Thanks!

I get using %if custom = such and such%, but what I find is that I'd rather do more interesting logic.

Is there a NOT operator?

I've tried !=, <>, and NOT to no avail.

Glad you like the feature.  This is the kind of feedback that really helps improve the product.  We currently do not have a 'NOT' operator, but please file it into the Ideas Portal on the support site.  Can you also provide some use cases?

We are replacing an existing (bad) WLAN product, but don't want to have both hot at the same time on the same SSID.

I want use custom_variable_2 to indicate variation from normal -- my preference is "Install" and blank.

So what I'm actually looking for is a test for blankness.

%if %custom_variable_2%=Install%

set dummy SSID

put radios in spectrum monitor mode

etc.

%endif%

%if custom_variable_2%NOT=Install%

do normal stuff

%endif%

I'm finding out that the synatx I'm using above isn't actually working.  Is it possible to test the variable for a specific string, or is it just a test of filled or not filled?

--Matthew

Templates only test the existence or not of a variable on the device's variable listing.  It's not testing the content of the variables.

Then I think I'll just head on over to the feature request page...

Hi msabin.

Did you ever get this to work, either with a feature upgrade or a workaround?

Is it possible to check if a field is NULL?

what i am trying to achieve is setting bandwidth limits as per a custom_variable

I have got the following:

 %if custom_variable_1%
 bandwidth-limit %custom_variable_1%
 %endif%
bandwidth-limit 2048

This appears to work, but has the side effect of causing an error in the config

Apologies for resurrecting an old post

TIA

I use that syntax for 7 or 8 variables now, all seem to work fine and I don't have any errors in the config reported.

The answer was that %if custom_variable_1% is essentially testing for NULL and if NULL then the if returns negative and the line is skipped.

What version of iAP/Airwave are you on, and what error are you getting.

Hi Matthew,

We are on AMP 7.7.13 and iAP 6.4.2.0.

When looking at the config, it shows the 2 bandwidth lines as such

Desired   bandwidth-limit 2048
          bandwidth-limit 768

Looking at the VC and the line shows

Configuration:    Error (Configuration contains invalid commands)

running a repair doesnt seem to resolve the issue.  I am 99.999% sure its not anything else in the config as if i remove the logic and revert back to

 %if custom_variable_1%
 bandwidth-limit %custom_variable_1%
 %endif%

The error doesnt appear, making me think that the rest of the config is OK, and its this bit causing the issue.

 TIA

Yeah, I ran into the same behavior.

My solution was to dedicate a variable to that valueand set it for all locations.

We enter the "default" or "normal" value at all sites, then change it for those which need a variation.

Hi Matthew,

Glad its not just me :)

What method did you use to set all of them as a "default"? 

Did you use the template to set the default limit then manually change the ones that required a different limit?

TIA

G

Using the word "default" may have been misleading.

I think your conclusion is what I'm doing:

I use the variable to set the value for all sites. Enter the normal value when you set up a site, them edit it as you discover a need to make the change.
