ADDC manually managed device, device displays openflow connection fail

ADDC manually managed device, the device displays openflow connection fail, controller north-south integration. The controller is deployed as a single virtual machine.

ADDC manually managed device, the device shows openflow connection fail, controller north-south integration. Pinging the controller northbound address from the device succeeds, but pinging the southbound address fails.

The device can ping the controller (CTL) northbound address but fails to ping the southbound address. Pinging the gateway of the controller (CTL) within the DC pod also fails, while pinging addresses within its own pod succeeds.

Check that the NIC in the pod is in Running state. When capturing packets with tcpdump in the DC pod, the device can immediately ping the controller (CTL) southbound address once packet capture starts. Since tcpdump enables promiscuous mode by default, it is suspected that the virtual machine NIC does not have promiscuous mode enabled.

Use ifconfig ens160 promisc in the controller (CTL) background to enable promiscuous mode for the virtual NIC. After enabling, the device is successfully controlled (Ctl).
