Figure 8: QFX5100-48T Port Panel
The QFX5100-48T can be used as:
•
A standalone switch.
•
A Node device in a QFabric system.
The QFX5100-48T is supported on both the QFX3000-G and QFX3000-M QFabric systems.
•
A primary, backup, or line card in a QFX Virtual Chassis.
A QFX Series Virtual Chassis allows you to interconnect up to ten QFX5100, QFX3500, or QFX3600,
switches into one logical device and manage the device as a single chassis using a ring topology.
•
A line card in a QFX5110 Virtual Chassis.
You can configure up to ten QFX5110 and QFX5100 switches into one logical device and manage the
device as a single chassis using a ring topology. In a QFX5110 Virtual Chassis, configure QFX5110-32Q
as the primary and backup. Junos OS Release 17.3R2 or later is required on all members for QFX5110
VCF with QFX5100-48T leaf devices.
•
A leaf device in a standard QFX5100 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, four QFX5100 devices can
be configured as spine devices.
In a QFX5100 VCF, the QFX5100-48T is always a leaf device and a QFX5100-24Q is the spine device.
•
A leaf device in a QFX5110 VCF.
A QFX5110 VCF must have a minimum of two QFX5110-32Q as spine devices. Junos OS Release
17.3R2 or later is required on all VCF devices for QFX5100-48T leaf devices to operate in a QFX5110
VCF.
•
A satellite device in a Junos Fusion system.
Junos OS Release 14.2.3 or later is required for Junos Fusion.
•
QFX5100-48TH
As shown in Figure 9 on page 26, the QFX5100-48TH is the same form factor and port configuration
as the QFX5100-48T. The QFX5100-48TH is specifically designed for Juniper Networks Cloud Data
Center and comes pre-configured with Satellite Network Operational System (SNOS) instead of Juniper
