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. See “Interface Specifications for SFP, SFP+, and QSFP+ Transceivers for
the QFX Series” on page 94.
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 operatingasa Nodedevice, ports 0 through 7 are default FTEports; 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:
•
Default mode
All 24 QSFP+ ports on the switch (PIC 0) are channelized by default (96 ports). With
QFX-EM-4Q Expansion Modules (PIC 1) and (PIC 2), the QSFP+ ports are supported
for access or uplink ports, but cannot be channelized. Ports are over-subscribed In this
mode and could be subject to packet-loss. You can have one of two port combinations:
32 40-Gbps QSFP+ ports, or 96 10-Gigabit Ethernet ports plus 8 40-Gbps QSFP+
ports.
•
104 port mode
