A critical step in making a vQFX work is correctly connecting the RE and PFE VMs. The standard internal connection is between the interface on the RE and the em1 interface on the PFE . Without this link, the control and data planes cannot communicate, and the switch will not function.
Unlike a monolithic virtual machine, the Juniper vQFX10000 uses a dual-VM architecture to accurately simulate a physical switch. To make your deployment work, you must understand how these two components interact: vqfx202r110reqemuqcow2 work
: Incompatible CPU flags. Fix : Change CPU to host-model instead of host-passthrough : A critical step in making a vQFX work
User-defined switch ports are typically mapped to the (unlike the vMX, where they map to the PFE). RE Interface em0 is used for the management/admin VLAN. 3. Deployment Steps (General) Juniper vQFX RE - GNS3 Unlike a monolithic virtual machine, the Juniper vQFX10000
Connect em1 (or the second adapter interface) of the RE directly to em1 of the PFE. This dedicated channel allows the control plane to populate chassis linecards and activate operational interfaces ( xe-0/0/0 , et-0/0/0 ).
