Cisco AIR-CAP1552SA MAP drops off showing spamApTask0 messages

On WLC5508 with 7.6.110.0 image, what could be the reason for MAP AIR-CAP1552SA to drop off from its RAP for 7 hours after 15 days of working?

 

Apparently, the MAP joined back after seven hours with following messages below. (I have obfuscated actual mac address by xx:xx.)

During the dropped period, the WLC did not receive any CAPWAP discovery/join or show any other messages from these two APs.

There is a Primary and Secondary WLC, and other APs. WLC had been up for 71+ days at that time. So, WLC or RAP were not down.

 

The WLC and APs are in the same country code - India domain.

 

WLC Image:

Product Version.................................. 7.6.110.0

Bootloader Version............................... 1.0.16
Field Recovery Image Version..................... 1.0.0
 

 

AP Image:

System image file is "flash:/c1520-k9w8-mx.152-4.JB4/c1520-k9w8-xx.152-4.JB4"

 

 

The following messages were shown:

The MAP has the same image as WLC, exists in the mac-filtering list, and was joined thru a RAP (CAP1552) for 15 days.

 

1. Why was MAP showing no image in 'bundleApImageVer: ' message above?

2. What does 'Spam AP Queue is FULL' mean? When is this message seen? I searched but this message couldn't be found in WLC error list.

 

There are no AP crash log on the WLC. The MAP is three hops away. All APs are already in the Mac Filtering list and on the same subnet as WLC.

 

Any ideas? Thanks.

Thanks, salodh and mohanak

Thanks, salodh and mohanak!

This CSCuo06388 is the closest issue I find to the one described in our scenario. It has been apparently fixed in Rel 8.0(0.72).

In this bug report, the log displays the AP at least has the image.

 

In our original issue, the AP doesn't seem to have an image when it displays:

*spamApTask0: Aug 05 12:29:44.546: apType: Ox14 bundleApImageVer:

*spamApTask0: Aug 05 12:29:44.546: Could not find image version of bundled AP(apType: 20)!!!

Also, the existing AP drops off from the WLC for up to few hours and then joins back to the WLC.

 

Please add comments here If anyone knows when this bundleApImageVer: without image message is seen. Thx.

PS. For others, CSCts55071 was fixed in Rel 7.0 MR5 and it prevented new AP joining WLC when SPAM-Q full.

SPAM-Q full can cause WLC to

SPAM-Q full can cause WLC to refuse all new associations or crash
