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

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.

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?

Could you share Aruba TAC ticket number?

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 Pavan, unfortunatley we never seem to be given a TAC number - it all goes through our reseller

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

Hi,

 

Login to CLI as appadmin user and stop the service

 

# service status all  (List all the services)

# service stop cpass-extensions
