recommended in the master, backup, or line card role. When mixed with QFX3500 or
QFX3600 devices, configure the QFX5100-48T device in the master and backup roles.
See Connecting QFX Series Switches in a Virtual Chassis for cabling diagrams.
To connect a QFX5100-48T device as a leaf device in a Virtual Chassis Fabric (VCF), you
need a pair of dedicated ports and cables that link each spine device and leaf device in
the VCF. All spine devices have at least one direct VCP connection to each leaf device in
the VCF. See "Connecting a QFX5100 Device in a Virtual Chassis Fabric" on page 127
a cabling diagram.
The QFX5100-48T device operates as a standalone switch, a member of a QFX Virtual
Chassis, or as a leaf device in a Juniper Networks Virtual Chassis Fabric (VCF). QFX Virtual
Chassis support up to 10 members. VCF supports 20 total devices, of which 4
QFX5100-24Q devices can be configured as spine devices.
BEST PRACTICE:
device (except QFX5100-24Q-AA) as leaf devices.

To connect a QFX5100-48T switch as a Node device in a QFabric system, you need:
Four QSFP+ uplink ports on each QFX5100-48T Node device to connect to the data
plane network through the QFX3008-I or QFX5100-24Q Interconnect devices.
The two remaining QSFP+ uplink ports on each QFX5100-48T Node device connect
to the data plane network through the QFX3008-I or QFX5100-24Q Interconnect
