Dell C9000 Series Networking Configuration Manual page 841

The above procedure brings up the devices in Dell Networking OS 9.10(0.0). To get a dual homing
setup, you need to have a VLT domain running in two systems with the same OS version. Refer to
Setting up Dual Homing.
When you upgrade a standalone system to OS 10.0(0.0) and then connect a PE later, there might be a
mismatch between the versions. In this situation, the PE remains offline and the system displays the
following:
