The port panel of the QFX5100-48T device supports 48 10GBASE-T ports and 6 quad
small-form factor pluggable (QSFP+) ports. Forty-eight copper physical ports (
) are tri-speed and support up to 10-Gigabit Ethernet. These 10GbE/1GbE/100 Mbps
47
ports can be configured as access ports. See
and QSFP+ Transceivers for the QFX Series" on page 94
for SFP+ DAC Cables for the QFX Series" on page
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. See
Cables for the QFX Series" on page
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 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 187
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.
