Unable to Import configuration on airwave from controller 

Apr 09, 2015 10:40 AM

Environment : Airwave version 7.7 + , monitoring/managing Aruba controller

 

Unable to Import the config of a controller, and end up showing mismatch on Airwave.

when we doing an import configuration, if we do a # tail -f  /var/log/httpd/error_log  from the airwave CLI, we could see the below crash:

TableRowBase.pm line 127.
insert() - DBD::Pg::st execute failed: ERROR:  invalid input syntax for integer:"24,46" [for Statement "INSERT INTO aruba_ssid_prof

  wmm_uapsd,
  ap_folder_id,
 
This crash in the httpd/error_log:
TableRowBase.pm line 127.
insert() - DBD::Pg::st execute failed: ERROR:  invalid input syntax for integer:"24,46" [for Statement "INSERT INTO aruba_ssid_prof

  wmm_uapsd,
  ap_folder_id,

Explains that in the controller config, we enabled WMM in SSID profile and configured the DSCP mapping with two integer values, instead of one. in this above example error, we configured "24,46".

We could check on the controller by doing this: (controller's CLI)

# show wlan ssid-profile <ssid profile name>

Please look in the output and If you see two values for anyone of the dscp mapping for wmm (wireless multimedia) (usually there will be 4) for example, for this SSID profile we can see 24,46 for DSCP mapping for WMM voice AC.

(controller) #show wlan ssid-profile <test ssid>

***************************************
This setting is to set the priority  for that module's traffic. if we have two values, it is causing this issue, we could change that value to one. if nothing configured for wmm settings on the controller the default value will be one integer. for more info on how to configure, WMM settings, what are the default values etc, please refer to the links in related links section.
 
steps to remove the extra integer value from the controller are below:

# config t
# wlan ssid-profile <ssid profile name>
# wmm-vo-dscp  <enter one value>

Hit enter to save it.

wmm-vo-dscp is for voice traffic and likewise below are for others.

(TR-WLC7210-01) (SSID Profile "test-VOIP") #wmm-?
wmm-be-dscp             DSCP used to map WMM best-effort traffic
wmm-bk-dscp             DSCP used to map WMM background traffic
wmm-override-dscp-map.. Override DSCP Mappings for WMM clients
wmm-ts-min-inact-int    WMM TSPEC Min Inactivity Interval(0 - 3600000 msecs)
wmm-uapsd               Wireless Multimedia (WMM) UAPSD Powersave
wmm-vi-dscp             DSCP used to map WMM video traffic
wmm-vo-dscp             DSCP used to map WMM voice traffic

After making this change, please do an audit and re-import the config, we should be able to import.
