Features and Benefits
• Topology-Independent In-Service Soware Upgrade
(TISSU
*
): With its Intel core processor, the QFX5100
allows Junos OS to run within a virtual machine (VM) on
Linux. Junos OS runs in two separate VMs in active and
standby pairs; during soware upgrade cycles, the switches
seamlessly move to the newer soware version while
maintaining intact data plane trac. This true Topology-
Independent ISSU, an industry-first soware upgrade feature
for a fixed-configuration top-of-rack switch, is supported
across all Layer 2 and Layer 3 protocols and doesn’t need the
support of any other switches to perform an image upgrade.
• Automation: The QFX5100 switches support a number
of features for network automation and plug-and-play
operations. Features include zero-touch provisioning,
operations and event scripts, automatic rollback, and
Python scripting. The switch also offers support for
integration with VMware NSX Layer 2 Gateway Services,
Puppet, and OpenStack.
• Flexible Forwarding Table: The QFX5100’s Flexible Forwarding
Table (FFT) allows the hardware table to be carved into
configurable partitions of Layer 2 media access control (MAC),
Layer 3 host, and Longest Prefix Match (LPM) tables. In a
pure L2 environment, the QFX5100 supports 288,000 MAC
addresses. In L3 mode, the table can support 128,000 host
entries, and in LPM mode, it can support 128,000 prefixes.
Junos OS provides configurable options through a command-
line interface (CLI) so that each QFX5100 can be optimized for
dierent deployment scenarios.
• Intelligent Buffer Management: The QFX5100 switches
have a total of 12 MB shared buffers. While 25% of the total
buffer space is dedicated, the rest is shared among all ports
and is user configurable. The intelligent buffer mechanism
in the QFX5100 effectively absorbs traffic bursts while
providing deterministic performance, significantly increasing
performance over static allocation.
• Insight Technology for Analytics: The QFX5100 provides
dynamic buffer utilization monitoring and reporting with an
interval of 10 milliseconds to provide microburst and latency
insight. The data can be viewed via CLI, system log, or
streamed to external servers for more analysis. Supported
reporting formats include Java Script Object Notification
(JSON), CSV and TSV. These files can be consumed
by orchestration systems, SDN controllers, or network
management applications (such as Juniper Networks Junos
Space Network Director) to make better network design
decisions and identify network hotspots.
• MPLS: QFX5100 switches support a broad set of MPLS
features, including L3 VPN, IPv6 provider edge router (6PE),
RSVP traffic engineering, and LDP to allow standards-based
network segmentation and virtualization. The QFX5100 can
be deployed as a low-latency MPLS label-switching router
(LSR) or MPLS PE router in smaller scale environments. The
QFX5100 is the industry’s only compact, low-latency, high-
density, low-power switch to offer an MPLS feature set.
• VXLAN: The QFX5100 supports Layer 2 gateway services
that enable VXLAN-to-VLAN connectivity at any tier of the
data center network, from server access to the edge. For
MAC address learning, the QFX5100 supports both EVPN as
well as OVSDB, and also integrates with VMware NSX.
• FCoE: As a Fibre Channel over Ethernet (FCoE) transit switch,
the QFX5100 provides an IEEE data center bridging (DCB)
converged network between FCoE-enabled servers and an
FCoE-enabled Fibre Channel storage area network (SAN).
The QFX5100 oers a full-featured DCB implementation that
* TISSU supported only in standalone mode, not in Virtual Chassis Fabric deployments.
