The port panel of the QFX5100-48T and QFX5100-48TH devices supports 48 10GBASE-T
ports and 6 quad small-form factor pluggable (QSFP+) ports. Forty-eight copper physical
ports ( 0 through 47 ) are tri-speed and support up to 10-Gigabit Ethernet. These
10GbE/1GbE/100 Mbps ports can be configured as access ports. See Determining Interface
Support for the QFX5100 Device.
The remaining six ports (

QSFP+ socket can operate either as a single 40 Gbps port or as a set of 4 independent
10 Gbps ports using QSFP+ breakout cables. The 40 GbE ports can be configured as
either access ports or as uplinks.
To connect a QFX5100-48T device as a member in a QFX Virtual Chassis, you need a
pair of dedicated ports and cables that link each member in the Virtual Chassis into a
ring topology. Each member in the ring has at least one direct Virtual Chassis port (VCP)
connection to a upstream and downstream member. QFX5100-48T switches are
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 and EX Series Switches in a QFX 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 for a cabling diagram.
The QFX5100-48T device operates as a standalone switch, a member of a QFX Virtual
Chassis, a member of a QFX5110 Virtual Chassis, act as a leaf device in a Juniper Networks
Virtual Chassis Fabric (VCF). QFX Virtual Chassis and QFX5100 Virtual Chassis both
support up to 10 members. VCF supports 20 total devices, of which 4 QFX5100-24Q
devices can be configured as spine devices.
