ports or uplink ports, but only ports 0 and 2 can be channelized using port mode. For
full details on the different port channelization modes, see

can be configured as either access ports or uplink ports.
This switch provides the hardware support to enable PTP boundary clocks by using
the QFX-PFA-4Q module. The QFX5100-24Q-AA also supports GPS in and out signals
when QFX-PFA-4Q is installed.
The CPU subsystem of this switch includes a 2-port 10-Gigabit Ethernet network
interface card (NIC) to provide a high bandwidth path or to alternate traffic path to
guest VMs directly from the Packet Forwarding Engine.

The QFX5100-24Q-AA can be used as a standalone switch that supports high frequency
statistics collection. Working with Juniper Networks Cloud Analytics Engine, this switch
monitors and reports the workload and application behavior across the physical and
virtual infrastructure.
The QFX5100-24Q-AA supports the following expansion modules to increase port
density:
QFX-PFA-4Q (double-wide), which provides four additional QSFP+ ports. See
Figure 7 on page 8.

QFX-EM-4Q (single-wide), which provides 4 additional 40-Gigabit Ethernet QSFP+
ports. See Figure 4 on page
EX4600-EM-8F (single-wide), which provides 8 additional 10-Gigabit Ethernet SFP+
ports. See Figure 5 on page
The QFX5100-24Q switch supports the QFX-PFA-4Q and you must take the switch
offline before replacing the expansion module. Any combination of EX4600-EM-8F
and QFX-EM-4Q is also supported. These two expansion modules can be hot-inserted
or hot-removed. However, when an EX4600-EM-8F is inserted instead of a QFX-EM-4Q,
the new configuration causes the interfaces to temporarily go down. Likewise, when
