1121 not registering to WLC

I was converting AP’s from Autonomous to Lightweight AP’s yesterday when I ran into issues with a couple of old 1121G. I only saw the AP register to the controller for 3-4 seconds before it disconnected. While pinging the AP it responded for 1 minute before it did go into a reboot.

I then logged into the WLC to do a debug. I used the following debug command:

(Cisco Controller) >debug capwap errors enable

The output from this repeated itself every time the AP was up and running.

Security processing of Image Data failed for AP was a message in the output that I thought was strange and also other references to the image. I then checked the Cisco Wireless Controller Compability Matrix, to my dissapointment the AP was no longer supported. It ended up with a long and slow process of having one of the local guys in Chile downgrading from Controllerbased AP to a Standalone….

Could not connect to node1 : No route to host

Today I had some issues when working on a SRX650. We had to replace the Services and Routing Engine a few days ago. When I was supposed to get the cluster back online I got the following error message when trying to run a few of the commands on the device:

Could not connect to node1 : No route to host

I got this error when typing show interface ge-0/0/2. I also entered the command on the node1 so I felt it was a bit strange that node1 could not connect to node1.

The firewall was also saying that it was in a hold mode

{hold:node1}

So it was not showing as secondary or primary. It was keeping this status all the time and didn’t try to go to any other modes while the issue was occuring.

The reason for my issues was that I had not deleted all the default config from the new Service and Routing engine card that we got. My config was not correct for all the cluster ports since some of the ports in the cluster is dedicated to cluster services (on the SRX650 it is ge-0/0/0 (fxp0) and ge-0/0/0 (control plane)). These ports are not to be configured as network ports and that is the reason for my issues. When I deleted the config and set a default root authentication password everything was connected. When I did a commit from the primary node the config was correct on both devices and everything connected succesfully.

During my search on the internet I read that some people also forgot to set the reth-count and got the same error. The command to set the number of reth interfaces is:

set chassis cluster reth-count 4

A great source for more information is the following chapter of the book “Juniper SRX Series” written by Brad Woodberg and Rob Cameron.

Problems with HP Port Replicator 3005pr

I had some issues with the screens and usb devices after upgrading from Windows 8 to Windows 10 the other day. It was only one screen that was working and none of the USB devices where working.

When trying to update the driver for HP Port Replicator 3005 pr I got the following error message: “A previous uninstall of HP Port Replicator Software is not yet complete. Please reboot your computer and run this installer again to installation.”

I tried several solutions to solve the issue but none of the ones I found on the internet helped me. Most of the problems was solved with the compability mode but for some reason that was not good enough for me. After some troubleshooting I discovered that it failed during the update of the displaylink software. I then downloaded the Display Link software manually and tried to run the setup. I got a message saying that the installation had failed (I don’t have a screenshot or the correct words).

When I did the complete uninstall of the DisplayLink software I was able to install the port replicator driver. The uninstall software can be found here. The software is named “DisplayLink Installation Cleaner” and starts a command window where you will press enter to remove the old software.
