Qfabric Systems; Channelizing Interfaces (Non-Qfabric) - Juniper QFX5110 Series Hardware Documentation

QSFP+ to QSFP+ active optical cables (AOC)
QSFP+ to SFP+ active optical breakout cable (AOCBO)
Access ports
You can use 40-Gigabit Ethernet QSFP+ transceivers and QSFP+ direct attach copper cables in any
downstream port. See
Uplink ports
You can configure up to 4 of the 40 GbE ports as uplinks. Each additional QFX-EM-4Q, Expansion
Module adds the switch uplink capacity by 2 for a total of 8 uplinks.
To connect a QFX5100-24Q switch as a Node device in a QFabric system, you need:
Four QSFP+ uplink ports on each QFX5100-24Q Node device to connect to the data plane network
through the QFX3008-I or QFX5100-24Q Interconnect devices.
Two additional QSFP+ uplink ports on each QFX5100-24Q Node device connect to the data plane
network through the QFX3008-I or QFX5100-24Q Interconnect devices. .

QFabric Systems

The QFX5100-24Q operates as a Node device in both the QFX3000-G and QFX3000-M QFabric systems.
Additionally, the QFX5100-24Q can be configured as an Interconnect Device in QFX3000-M QFabric
systems allowing a maximum of 16 Node devices. The QFX5100-24Q may not be mixed with QFX3600-I
Interconnect devices in the same QFabric system.
When operating as a Node device, ports 0 through 7 are default FTE ports; ports 8 through 15 can be
configured as either uplink (FTE) or access ports (XLE). In the port range 8 through 23, only 12 ports can
be channelized when the 2 QFX-EM-4Q are installed.
NOTE: The EX4600-EM-8S expansion module is not supported on the QFX5100-24Q device
in a QFabric system.

Channelizing Interfaces (Non-QFabric)

When fully populated with 2 QFX-EM-4Q Expansion Modules, the QFX5100-24Q device has 128 physical
ports. However, only 104 logical ports can be used for port channelization. Depending on the system mode
you configure for channelization, different ports are restricted. If you attempt to channelize a restricted
port, the configuration is ignored. The following system modes are available on the QFX5100-24Q device:
