NCS failing to gather current clients from APs

We're running NCS 1.1.0.58. Since updating to this release from the 1.0 release, the 'Autonomous AP Client Status' and 'Lightweight Client Status' background tasks have been failing with message 'java.lang.NullPointerException'.  I believe as a result of this that the 'Current Clients' tab on an AP monitoring screen just reports 'No data available'.

Does anyone have any suggestions of how to fix this?

Thanks,

Sean

I was getting that error, so I opened a TAC Case and they patched my system. I have other issues but this was fixed with a patch after openign a case.

Hi;

We had the same problem, running NCS 1.1.0.58. I saw that 1.1.1.24 was out, so I downloaded the NCS-upgrade-bundle-1.1.1.24.tar.gz and applied it. Seems to have fixed the problem, no need for the horror of opening a TAC case.

Instructions here:

Shut down NCS before performing the upgrade. To stop NCS, enter the ncs stop command.


Use the following command to upgrade from NCS 1.0 to NCS 1.1.1.24:

# application upgrade NCS-upgrade-bundle-1.1.1.24.tar.gz ncs-ftp-repo

In the preceding command, NCS-upgrade-bundle-1.1.1.24.tar.gz is the upgrade bundle file, which is available for download.

The repository used in the example, ncs-ftp-repo, can be any valid repository.

Examples of repository configurations follow.

FTP Repository:

# configure

(config)# repository ncs-ftp-repo

(config-Repository)# url ftp://ip-address

(config-Repository)# user ftp-user password plain ftp-user

(config-Repository)# exit

(config)# exit

#

SFTP Repository:

# configure

(config)# repository ncs-sftp-repo  

(config-Repository)# url sftp://ip-address

(config-Repository)# user ftp-user password plain ftp-user

(config-Repository)# exit

(config)# exit

#

TFTP Repository:

# configure

(config)# repository ncs-tftp-repo

(config-Repository)# url tftp://ip-address

(config-Repository)# exit

(config)# exit
