instances cannot get fixed ip

I setup a controller+network node by DevStack with VLAN network type using Kilo version(networking_hyperv is installed), and a hyper-v compute node by cloudbase hyper-v compute driver(Kilo version too). Everything works well except that instances cannot get fixed ip.

>Get-VMNetworkAdapterVlan -VMNetworkAdapterName ec49017e-6d5b-489e-80ff-a311a67dee07 -ErrorAction Ignore

VMName            VMNetworkAdapterName                 Mode   VlanList
------            --------------------                 ----   --------
instance-00000007 ec49017e-6d5b-489e-80ff-a311a67dee07 Access 27

And there are below error messages in neutron-hyperv-agent.log:

Could anyone help on this?

I finally figure it out. My problem here is my physical switch connected to the interface used for VM sets up a VLAN range which mismatches the vlan range I used when installing openstack:

ML2_VLAN_RANGES=default:671:690

Another possibility is iptable rules that prohibit icmp request and you need delete them:

# iptables-save | grep icmp
......
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
