NCS failing to gather current clients from APs

[ffacilities]

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
