172.17.0.1 address in ClearPass

Afternoon all

Been trying to add another authentication source to our clearpass this morning. ClearPass is behind a firewall so doing basic network type troubleshooting, I see a reply from an IP not even configured on our network or indeed within ClearPass itself:

 

[appadmin@PHXA9CP02]# network ping 172.17.17.254
PING 172.17.17.254 (172.17.17.254) 56(84) bytes of data.
From 172.17.0.1 icmp_seq=1 Destination Host Unreachable
From 172.17.0.1 icmp_seq=2 Destination Host Unreachable
From 172.17.0.1 icmp_seq=3 Destination Host Unreachable
From 172.17.0.1 icmp_seq=4 Destination Host Unreachable

 

Looking at some posts here I see an issue with running ClearPass on VM's since 6.6.x and a Docker0 address?? - We have HW appliance, do I take it this platform is also affected? Is the fix the same - Stop Extension Services?

 

Thanks

It depends, what version of CPPM are you running?
