and switch can occur. We recommend either using the top port row
exclusively, or bottom port row exclusively, for copper transceivers.
To connect a QFX5100-48S switch as a node device in a QFabric system, you need:
Four QSFP+ uplink ports on each QFX5100-48S 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 QFX5100-48S Node device connect
to the data plane network through the QFX3008-I or QFX5100-24Q Interconnect
devices. See Interface Specifications for SFP, SFP+, and QSFP+ Transceivers for the
QFX Series.
To connect a QFX5100-48S switch 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. QFX5100-48S switches are
recommended in the master, backup, or line card role. When mixed with QFX3500 or
QFX3600 devices, configure the QFX5100-48S in the master and backup roles. See
Connecting QFX Series Switches in a Virtual Chassis for cabling diagrams.
To connect a QFX5100-48S switch as a spine or 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 for a cabling diagram.
BEST PRACTICE:
QFX5100 and the EX4300, use QFX5100-24Q as spine devices. In the
maximum configuration of 20 total devices, up to four QFX5100-24Q devices
may be used as spine devices. All members can be connected to the spine
using QSFP+ ports. You can configure the QFX5100-96S as a spine in an all
QFX5100-96S VCF or in a mixed VCF comprised of EX4300 and
QFX5100-96S.
