The QFX5100-24Q can be used as:
A standalone switch.
An interconnect device in a QFX3000-M QFabric system.
A Node device in a QFabric system.
The QFX5100-24Q is supported on both the QFX3000-G and QFX3000-M QFabric
systems. A QFX5100-24Q Node device is equivalent to 80 10-Gbps interfaces and
4 40-Gbps interfaces.
A master, backup, or line card in a QFX Virtual Chassis.
A QFX Series Virtual Chassis allows you to interconnect up to 10 QFX3500, QFX3600,
or QFX5100 switches into one logical device and manage the device as a single
chassis in a ring topology.
Use QFX5100-24Q switches as the master and backup in a QFX Virtual Chassis.
A spine or leaf device in a Virtual Chassis Fabric (VCF).
VCF uses Virtual Chassis technology to interconnect multiple devices into a single
logical device and manage that device as a single logical device inside of a fabric
architecture. VCF architecture supports up to 20 total devices in a spine and leaf
topology. Of those 20 devices, 4 QFX5100 devices can be configured as spine devices.
BEST PRACTICE:
QFX5100-24Q can also be used in leaf-mode when there is another
QFX5100-24Q in spine-mode.
A satellite device in a Junos Fusion system.
Junos OS Release 14.2.3 or later is required for Junos Fusion.
The QFX5100-24Q switch has two bays on the port panel for optional expansion
modules. The QFX5100-24Q supports two expansion modules to increase port density:
QFX-EM-4Q, which provides four additional 40-Gigabit Quad SFP+ (QSFP+) ports.
See Figure 4 on page 7.
Use QFX5100-24Q as the spine device. The
