Re: [Quantum][Grizzly] Second NIC is not getting IP address from the network

 

Thanks Aaron for quick response.

OS dashboard shows that both the NIC got their IP addresses from respective
DHCP servers. It also shows the second IP address which actually is
requested by Cirros VM image. If i run udhcp manually from the VM, will it
get the same IP address from its DHCP server? If yes, than i think there is
no issue, but if not then i think it will create inconsistency on what
dashboard is showing and what actual IP address it got assigned.
