hold on...how are you changing the MGMT IP? are you working directly on the bigip config files? If you're not fully familiar with F5 config, you shouldn't be doing that.

 

To change the MGMT IP from the F5 webGUI, go to System >> Platform

I can confirm the ip 61 is from BIGIP. When I disconnect the link. Both IP 61 and IP 70 can not be reached. And two mac address: Old IP: 10.220.69.61 MAC f4-15-63-f6-63-00 New IP: 10.220.69.61 MAC f4-15-63-f6-63-02

 

They are just difference a little bit.
