Creating a mixed-mode Virtual Chassis Fabric (VCF)

5 12 2017

In order to mix EX switches and QFX switches in the same VCF, you need to enable mixed-mode.   This requires all members of the VCF to reboot unfortunately:

{master:1}
imtech@sw0-24c> request virtual-chassis mode fabric mixed
fpc0:
--------------------------------------------------------------------------
Mode set to 'Fabric with mixed devices'. (Reboot required)

fpc2:
--------------------------------------------------------------------------
Mode set to 'Fabric with mixed devices'. (Reboot required)

fpc3:
--------------------------------------------------------------------------
Mode set to 'Fabric with mixed devices'. (Reboot required)

fpc1:
--------------------------------------------------------------------------
WARNING, Virtual Chassis Fabric mode enabled without a valid software license.
 Please contact Juniper Networks to obtain a valid Virtual Chassis Fabric License.

Mode set to 'Fabric with mixed devices'. (Reboot required)

Once you’ve cabled up your QSFP ports between the EX4300 you are adding and the QFX spines, you need to do the following:

Enable the VCF port on the QFX spine:

request virtual-chassis vc-port set pic-slot 0 port 48
