One Gigabit Ethernet RJ-45 management port on each QFX3100 Director device
provides connection to the management network through your out-of-band
management network.
QFX3500 , QFX3600, and QFX5100-48S, QFX5100-48T, and QFX5100-24Q Node
devices—Up to 128 Node devices can be connected to the QFX3000-G QFabric system.
NOTE: Up to eight Node devices can be configured as a network Node
group to connect to external networks. See
on page 22.
Four 40-Gbps quad small form-factor pluggable plus (QSFP+) uplink ports on each
QFX3500 or QFX5100 Node device connect to the data plane network through the
QFX3008-I Interconnect devices. Models QFX5100-48S, QFX5100-48T, and
QFX5100-24Q are supported as a QFX5100 Node device.
Two to eight 40-Gbps QSFP+ uplink ports on each QFX3600 or QFX5100 Node
device connect to the data plane network through the QFX3008-I Interconnect
devices.
NOTE: On QFX3600 the four QSFP+ ports (
as uplink ports by default.
Two Gigabit Ethernet RJ-45 or two SFP ports on each Node device provide connection
to the control plane and management network through the Virtual Chassis.
NOTE: All models of the QFX5100 have at least one RJ-45 port
an SFP cage (
The SFP cages can be configured for either 1 GbE copper or fiber SFP
transceivers. For details on the number of management ports on QFX5100
SKUs, see "QFX5100 Device Models" on page
QFX3008-I Interconnect devices—Two QFX3008-I Interconnect devices are required
for a QFX3000-G QFabric system. Up to four QFX3008-I Interconnect devices can be
used in a QFX3000-G QFabric sysem.
Up to 128 40-Gbps QSFP+ ports on each QFX3008-I Interconnect device connect
the QFX3500 and QFX3600 Node devices to the data plane network across
fiber-optic cables and a high-speed backplane.
Up to eight Gigabit Ethernet SFP+ interfaces (four per Control Board) connect each
QFX3008-I Interconnect device to the control plane and management network
through the Virtual Chassis.
