QSFP+ to QSFP+ active optical cables (AOC)
QSFP+ to SFP+ AOC breakout (AOCBO) cables
See "Interface Specifications for SFP, SFP+, and QSFP+ Transceivers for the QFX Series"
on page 94 and "Interface Specifications for SFP+ DAC Cables for the QFX Series" on
page 126. All 96 of these ports can be used for SFP+ transceivers or SFP+ direct attach
copper (DAC) cables. You can use 1-Gigabit Ethernet SFP+, 10-Gigabit Ethernet SFP+
transceivers and SFP+ direct attach copper cables in any access port.
CAUTION: Do not place a copper transceiver in an access port directly above
or below another copper transceiver. Internal damage to the access ports
and switch can occur. We recommend either using the top port row
exclusively, or bottom port row exclusively, for copper transceivers.
The port panel of the QFX5100-96S switch supports up to a maximum of 104 logical 10
GbE ports that can be distributed over 96 small form-factor pluggable plus (SFP+) and
8 quad small-form factor pluggable plus (QSFP+) transceivers . Because of an 104 port
restriction, only two of the eight QSFP+ can be channelized. Depending on how you set
the system mode for channelization, the behavior of channelization for the QSFP+
changes. The following system modes are available for the QFX5100-96S switch:
Non-oversubscribed
All 96 SFP+ ports on the switch (PIC 0) are supported. In this mode, the eight QSFP+
ports are not supported and cannot be channelized. There is no packet loss for packets
of any size in this mode.
Default mode
All 96 SFP+ ports on the switch (PIC 0) are supported. QSFP+ ports
be channelized. If ports
96
101 , 102 , and 103 are disabled.
The QFX5100-96S switch operates as a standalone switch, as a member in a QFX Virtual
Chassis, or as a spine or leaf device in a Virtual Chassis Fabric (VCF). QFX Virtual Chassis
support up to 10 members; VCF supports a total of 20 devices, of which 4 QFX5100
devices can be configured as spines. A QFX Virtual Chassis is cabled in a ring topology,
where a VCF is cabled in a spine and leaf topology.
Virtual Chassis
In a QFX Virtual Chassis, you can connect up to 10 standalone QFX5100-96S switches
into a QFX Series Virtual Chassis and manage the interconnected switches as a single
chassis. The advantages of connecting multiple switches into a Virtual Chassis include
better-managed bandwidth at a network layer, simplified configuration and maintenance
because multiple devices can be managed as a single device, increased fault tolerance
