ClearPass 6.6.5 VM picking up random IP Addresses

Hi, we are running a Cluster on 6.6.5 and after this version was installed yesterday, we have noticed that it is trying to attach itself to another IP Address within the same subnet. We have checked VM Ware and also Clearpass but can't find this random IP Address anywhere. Has anyone else ever had this issue?

We restarted the Servers and they then chose another random address. Within Clearpass, it is only showing the IP Address of the Publisher, Subscriber and VIP though.

 

Thanks

Re: Clearpass 6.6.5 VM picking up random IP Addresses

Jo, Thanks for the explanation. Without going into and huge explanation this is something we will be fixing in a future release. 

 

I'm still not sure how it's effecting other systems as that IP address range is used internally and is NATed out of the MGMT interface when CPPM communicates with external systems.

 

For now and based upon the fact that ClearPass is not being started/stopped very regularly your solution will be to stop the Extension service if you have to re-start ClearPass. This will remove the 172.17.x.x IP-address range from CPPM.

Re: Clearpass 6.6.5 VM picking up random IP Addresses

Hi,

 

Have you assigned static IP address to CPPM servers or DHCP ?  I found below KB for vmware which is assigning invalid ip after reboot.

Thanks Pavan, we use static ip addresses but a random ip is appearing on the vm console when we reboot the box. I'll pass that info onto my colleagues and ask them to take a look in the registry.

Re: Clearpass 6.6.5 VM picking up random IP Addresses

Thanks, we have found this is something called "Docker0" on CP - it's addresses keep increasing everytime we reboot the VM.

We've been on a webex with Aruba but they're unable to fix it - can anyone advise? Aruba found the Docker0 from logging in as arubasupport which we don't have access too.

Does anyone know if this "Docker0" address can be statically assigned?

Re: Clearpass 6.6.5 VM picking up random IP Addresses

So the CPPM docker host IP@ will likely be 172.17.0.1. If you want to stop this, try stopping the Extension Services. This should take this issue away.

Thanks Danny, is this via APIs? I'm trying to locate the extension services but can't find them

 

Thanks

Hi,

 

Login to CLI as appadmin user and stop the service

 

# service status all  (List all the services)

# service stop cpass-extensions
