Connecting QFX5110 in a QFX5110 Virtual Chassis Fabric
A Juniper Networks QFX5110 Virtual Chassis Fabric (VCF) is constructed using a spine-and-leaf architecture
and topology. In the spine-and-leaf architecture, each spine device is interconnected to each leaf device.
QFX5110 VCFs support a maximum of 20 members in a VCF. Use QFX5110-32Q as either the spine or
as a leaf device. Use QFX5110-48S, QFX5100-24Q, QFX5100-48S, QFX5100-48T, or QFX5100-96S
models only as leaf devices.
Figure 81 on page 296 shows cabling for a QFX5110 VCF with two QFX5110-32Q spine devices connected
to four QFX5110-48S as leaf devices, all using all QSFP28 ports as
the cabling for a QFX5110 VCF using QFX5110-32Q as spines and QFX5100-24Q leaf devices.
