BEST PRACTICE: In a mixed QFX5100 VCF environment with multiple models of QFX5100 and
the EX4300, use QFX5100-24Q as spine devices. In the maximum configuration of 20 total
devices, up to four QFX5100-24Q devices may be used as spine devices. All members can be
connected to the spine using QSFP+ ports. You can configure the QFX5100-96S as a spine in
an all QFX5100-96S VCF or in a mixed VCF comprised of EX4300 and QFX5100-96S.
As of Junos OS release 17.3R1, you can also connect a QFX5100-48S as a leaf device in a QFX5110 VCF
or as a member in a QFX5110 Virtual Chassis.
Figure 18 on page 38 shows the port panel of a QFX5100-48S switch.
