The Cisco Nexus® 2000 Series Fabric Extenders comprise a category of data center products designed to simplify
data center access architecture and operations. The Cisco Nexus 2000 Series uses the Cisco® fabric extender
architecture to provide a highly scalable unified server-access platform across a range of 100 Megabit Ethernet, 1
and 10 Gigabit Ethernet, unified fabric, copper and fiber connectivity, and rack and blade server environments. The
platform is well suited to support today’s traditional 1 Gigabit Ethernet environments while allowing transparent
migration to 10 Gigabit Ethernet, virtual machine-aware unified fabric technologies.
The Cisco Nexus 2000 Series Fabric Extenders behave like remote line cards for a parent Cisco Nexus switch.
The fabric extenders are essentially extensions of the parent Cisco Nexus switch fabric, with the fabric extenders
and the parent switch together forming a distributed modular system. This architecture enables physical topologies
with the flexibility and benefits of both top-of-rack (ToR) and end-of-row (EoR) deployments (Figure 1).
Figure 1. Cisco Nexus 2000 Series Fabric Extenders Provide Highly Scalable Unified Server-Access Connectivity
The Cisco Nexus 2000 Series architecture provides the following benefits:
●
Architecture flexibility: A common, scalable, and adaptive architecture across data center racks and points
of delivery (PoDs)1 supports various server options, connectivity options, physical topologies, and evolving
needs.
●
Highly scalable server access: 1 and 10 Gigabit Ethernet server access is scalable, with no reliance on
Spanning Tree Protocol.
●
Simplified operations: One single point of management and policy enforcement using upstream Cisco
Nexus switches eases the commissioning and decommissioning of server racks through zero-touch
installation and automatic configuration of fabric extenders.
●
Increased business benefits: Consolidation, cabling reduction, rack-space reduction, reduced power and
cooling, investment protection through feature inheritance from the parent switch, and the capability to add
functions without the need for a major equipment upgrade of server-attached infrastructure all contribute to
reduced operating expenses (OpEx) and capital expenditures (CapEx).
The Cisco Nexus 2000 Series design aligns with that of servers. It offers front-to-back cooling, compatible with data
center hot-aisle and cold-aisle designs, all switch ports at the rear of the unit in close proximity to server ports, and
all user-serviceable components accessible from the front panel. It also offers back-to-front cooling, with switch
ports in front of the chassis, aligned with the cold aisle, for optimized cabling in network racks. The Cisco Nexus
2000 Series is built for nonstop operation, with redundant hot-swappable power supplies and a hot-swappable fan
tray with redundant fans. Its compact 1-rack-unit (1RU) form factor takes up relatively little space, making it easy to
incorporate into rack designs. The fabric extenders are available in several models to provide speed, connectivity,
and port-density options (Figure 2).

Transceivers for Cisco Nexus 2000 Series and Cisco Nexus Parent Switch Interconnect Are in Front of the Fabric
Extenders
The Cisco Nexus 2000 Series provides two types of ports: ports for end-host attachment (host interfaces) and
uplink ports (fabric interfaces). Fabric interfaces, differentiated with a yellow color, are for connectivity to the
upstream parent Cisco Nexus switch.
A PoD is a module or group of network, computing, storage, and application components that work together to deliver a network
service. The PoD is a repeatable pattern, and its components increase the modularity, scalability, and manageability of data
centers.

Table 1 lists the Cisco Nexus 2000 Series Fabric Extenders. Fabric extenders can be mixed and matched to a
parent switch to provide connectivity options.
Table 1. Cisco Nexus 2000 Series Fabric Extenders
The Cisco Nexus 2248TP-E (Figure 3) is a general-purpose 1 Gigabit Ethernet fabric extender with enhancements
that target workloads such as large-volume databases, distributed storage, and video editing. Like the Cisco Nexus
2248TP, the Cisco Nexus 2248TP-E supports 48 x 100/1000BASE-T host-facing ports and four 10 Gigabit
Ethernet fabric interfaces. It also supports 32-MB shared buffers.
Figure 3. Cisco Nexus N2248TP-E
The Cisco Nexus 2248PQ 10 Gigabit Ethernet fabric extender (Figure 4) is the newest member of the Cisco Nexus
fabric extenders. It supports high-density 10 Gigabit Ethernet environments and has 48 x 1 and 10 Gigabit Ethernet
SFP+ host ports and 4 QSFP+ fabric ports (16 x 10 Gigabit Ethernet fabric ports). QSFP+ connectivity simplifies
cabling while lowering power and solution cost. The Cisco Nexus 2248PQ 10GE Fabric Extender supports FCoE
and a set of network technologies known collectively as Data Center Bridging (DCB) that increase the reliability,
efficiency, and scalability of Ethernet networks. These features allow support for multiple traffic classes over a
lossless Ethernet fabric, thus enabling consolidation of LAN, SAN, and cluster environments.
Figure 4. Cisco Nexus N2248PQ
The Cisco Nexus 2232PP 1 and 10 Gigabit Ethernet fabric extender (Figure 5) is an excellent platform for
migration from 1 Gigabit Ethernet to 10 Gigabit Ethernet and unified fabric environments. It supports FCoE and
DCB.
The Cisco Nexus 2232TM-E fabric extender (Figure 6) supports scalable 1/10GBASE-T environments, ease of
migration from 1GBASE-T to 10GBASE-T, and effective reuse of existing structured cabling. It comes with an
uplink module that supports eight 10 Gigabit Ethernet fabric interfaces. It is a superset of the Cisco Nexus 2232TM
with the latest generation of 10GBASE-T PHY, enabling lower power and improved bit error rate (BER). The Cisco
Nexus 2232TM-E supports DCB and LAN and SAN consolidation. FCoE support distances of up to 30 meters with
Category 6a and 7 cables from the adapter to the fabric extender.
Figure 6. Cisco Nexus N2232TM-E
Cisco Nexus 2000 Series Fabric Extenders connect to a parent Cisco Nexus switch through their fabric links using
CX1 copper cable, short-reach or long-reach optics, and the cost-effective Cisco Fabric Extender Transceivers.
Fabric Extender Transceivers are optical transceivers that provide a highly cost-effective solution for connecting
the fabric extender to its parent switch over OM3 or OM4 multimode fiber.
The fabric extenders behave like remote line cards for a parent Cisco Nexus 5000, 6000, or 7000 Series Switch.
Working in conjunction with Cisco Nexus switches, the fabric extenders extend the capabilities and benefits offered
by the parent Cisco Nexus switch while providing flexible, scalable, and cost-effective server access. Table 2
summarizes the Cisco Nexus 2000 Series parent switch support matrix.

Unified server access architecture: The Cisco Nexus 2000 Series offers a highly cost-effective access-layer
architecture for 100 Megabit Ethernet, Gigabit Ethernet, 10 Gigabit Ethernet, mixed Gigabit Ethernet, and
10 Gigabit Ethernet servers; Ethernet or unified fabrics; physical or virtual servers; and rack or blade server
environments.
●
Flexible physical topologies: The Cisco Nexus 2000 Series architecture allows the Layer 1 and 2 topologies
to be decoupled, therefore providing flexibility in physical architecture designs, including ToR, middle-of-row
(MoR), and EoR deployments, while allowing quick expansion of network capacity and remote line-card
portability across multiple parent switches. It is also space optimized for all these architectures.
Highly Scalable Access Layer
Today’s data centers must have massive scalability to manage the combination of an increasing number of servers
and a higher demand for bandwidth from each server. The Cisco Nexus 2000 Series increases the scalability of the
access layer to accommodate both sets of demands without increasing management points within the network.
●
Massive scalability: A deployment of Cisco Nexus 2000 Series Fabric Extenders connected to a Cisco
Nexus 5000, 6000, or 7000 Series Switch supports highly scalable 1 and 10 Gigabit Ethernet environments,
as shown in Table 2.
●
Layer 2 scalability: Reliance on Spanning Tree Protocol is eliminated between the fabric extender and the
parent switch, thus enabling a large, multipath, loop-free topology. Use of a single management entity to
support a large server domain allows policy to be enforced more efficiently and enhances Layer 2 data
center access scalability. Use of the virtual PortChannel (vPC) feature also allows fast convergence and
effective use of bandwidth in Layer 2 environments.
Simplified Operations
●
Single point of management: The Cisco Nexus 2000 Series Fabric Extenders are remote line cards for a
Cisco Nexus parent switch. All device configurations are managed on the parent switch, and configuration
information is downloaded to the fabric extender using in-band communication.
●
Software maintenance simplification: The Cisco Nexus 2000 Series software is embedded in the Cisco
Nexus parent switch software. The fabric extender is a ready-to-use device that automatically downloads
the software image from the parent switch in the same way that a line card downloads software from the
supervisor engine in a modular chassis. In-Service Software Upgrade (ISSU) on the fabric extenders
provides the capability to perform transparent software upgrades, reducing downtime and allowing
customers to integrate the newest features and functions with little or no negative effect on network
operation for Ethernet, storage, and converged network environments.
●
Switch feature consistency across a large number of servers: The Cisco Nexus 2000 Series forwards all
traffic to the parent Cisco Nexus switch over 10 Gigabit Ethernet fabric uplinks. Passing all traffic to the
parent switch allows traffic to be shaped according to policies established on the parent switch with a single
point of management. Standardizing on the Cisco Nexus switches allows data centers to support the same
switch features across the entire access layer with a single point of management.
Tenfold reduction in management points: The number of management points is significantly less than when
discrete switches are used at the top of the rack. A traditional 12-rack design using a discrete, redundant
pair of Gigabit Ethernet switches at the top of each rack has 24 management points. The equivalent
architecture using the Cisco Nexus 2000 Series has only 2 management points: a tenfold reduction in
management complexity.
Business Benefits
●
Cost-effective 10 Gigabit Ethernet solution: The Cisco Nexus 2000 Series is an excellent platform for
migration from 1 Gigabit Ethernet to 10 Gigabit Ethernet. Scalable 10 Gigabit Ethernet provides 10 times
the bandwidth for approximately twice the price of Gigabit Ethernet.
●
Consolidation: The Cisco Nexus 2000 Series protects an organization’s investment into the future,
supporting evolving data center needs by providing an easy migration path to low-latency 10 Gigabit
Ethernet, high-performance computing (HPC), virtual machine-aware networks. In addition, the combination
of the Cisco Nexus 5000 or 6000 Series and Cisco Nexus 2232PP or 2248PQ provides a unified network
fabric that supports LAN and SAN consolidation. Another benefit of the Cisco Nexus 2000 Series
architecture is the capability to collapse data center access and aggregation layers into one single layer.
●
Investment protection: The Cisco Nexus 2000 Series Fabric Extenders can be mixed and matched with a
common parent Cisco Nexus switch. New functions can be derived from upstream Cisco Nexus switches,
resulting in the capability to add new functions without the need for a major equipment upgrade.
●
Rack-space reduction: The Cisco Nexus 2000 Series consists of 1RU fabric extenders. The fabric
extenders are not physically constrained by the position of the Cisco Nexus parent switch in the physical
topology and are attached to the upstream Cisco Nexus switch through fabric links.
●
Cabling reduction with optimal intra- and inter-rack cabling options: The Cisco Nexus 2000 Series supports
ToR, EoR, and MoR deployment models. Placing the fabric extender at the top of the rack allows the use of
short cables from the rack to the servers, reducing cable costs, air dams, complexity, and opportunities for
error. The only inter-rack cabling required is for uplinks from the fabric extender to the parent switch.
Placing the parent Cisco Nexus switch at the end or middle of a row of racks makes efficient use of powerful
switching resources.
●
The Cisco Nexus 2000 Series supports an optimal cabling strategy that simplifies network operations and
prepares for future technologies:
◦Short intra-rack runs of copper: Intra-rack cables connecting to Gigabit Ethernet servers can be Category
5e, 6, 6a, or 7 with the Cisco Nexus 2148T, 2224TP, 2248TP, and 2248TP-E fabric extenders. Category
6, 6a, or 7 can connect 10GBASE-T servers to the Cisco Nexus 2232TM and 2232TM-E. Twinax cables
connect servers to ToR Cisco Nexus 2232PP fabric extenders. This model allows server racks and PoDs
to be preconfigured by server vendors so that they can be rolled into place and put into service upon
arrival.
◦Longer inter-rack horizontal runs of fiber: Cisco Nexus 2000 Series Fabric Extenders in each rack are
connected to parent switches that are placed at the end or middle of the row. For long reach between the
fabric extender and the parent switch, you can use Fabric Extender Transceiver, SFP+ short-reach (SR),
SFP+ long-reach (LR) optics over OM2 or OM3 cables, and QSFP+ optics for 40-Gbps connectivity.
Fiber protects investments into the future because it will support upcoming Ethernet standards, including
40 and 100 Gigabit Ethernet. If the distance to the Cisco Nexus 5000, 6000, or 7000 Series Switch is
less than 10 meters, you can use Twinax cables (CX1 direct attach). Alternatively, you can use copper
cables to reach EoR or MoR 1GBASE-T or 10GBASE-T fabric extenders.
Effective bandwidth utilization: Today’s data center servers are either single- or dual-homed to the network.
However, network designs almost always involve redundant deployment. Through the vPC feature support
on the Cisco Nexus 5000, 6000, and 7000 Series, a server can be dually connected to a pair of fabric
extenders, or each fabric extender can be connected to a pair of Cisco Nexus 5000, 6000, or 7000 Series
Switches, thus giving customers both server and fabric extender connectivity redundancy and providing
active-active connectivity with twice the bandwidth utilization as in active-standby or forwarding-blocking
configurations.
●
Reduced power and cooling needs: Cost-effective 10 Gigabit Ethernet solutions, optimal cabling, device
consolidation, rack-space reduction, and efficient bandwidth use all contribute to a significant reduction in
power and cooling needs in the data center.
Cisco Nexus 2000 Series Deployment Scenarios
The fabric extenders can be used in the following deployment scenarios:
●
Rack servers with 100 Megabit Ethernet, 1 Gigabit Ethernet, or 10 Gigabit Ethernet network interface cards
(NICs); the fabric extender can be physically located at the top of the rack and the Cisco Nexus parent
switch can reside in the middle or at the end of the row, or the fabric extender and the Cisco Nexus parent
switch can both reside at the end or middle of the row
●
10 Gigabit Ethernet and FCoE deployments, using servers with converged network adapters (CNAs) for
unified fabric environments with the Cisco Nexus 2232PP, 2248PQ, and 2232TM-E.
●
1/10GBASE-T server connectivity with ease of migration from 1 to 10GBASE-T and effective reuse of
structured cabling
●
Server racks with integrated lights-out (iLO) management, with 100 Megabit Ethernet or 1 Gigabit Ethernet
management and iLO interfaces
●
1 and 10 Gigabit Ethernet blade servers with pass-through blades
The Cisco Nexus 2000 Series can be used in conjunction with a Cisco Nexus parent switch in four main design
scenarios (shown in Figure 7):
●
Cisco Nexus 2000 Series Fabric Extenders single-connected to one upstream Cisco Nexus 5000, 6000, or
7000 Series Switch: In this deployment scenario, access-layer redundancy is achieved through redundant
server connections to two upstream distributed modular systems using vPC (Cisco Nexus 5000, 6000, or
7000 Series) or server NIC teaming to two Cisco Nexus 2000 Series Fabric Extenders.
●
Cisco Nexus 2000 Series Fabric Extenders dual-connected to two upstream Cisco Nexus 5000, 6000, or
7000 Series Switches (vPC): In this deployment scenario, access-layer redundancy is achieved through a
combination of Cisco Nexus 2000 Series Fabric Extenders dual-connected to an upstream parent switch
and server NIC teaming.
Enhanced vPC (EvPC): In this deployment scenario, access-layer redundancy is achieved in two ways:
through redundant connections between the Cisco Nexus 2000 Fabric Extenders and the Cisco Nexus
parent switches using vPC, and through redundant server connections to two fabric extenders using vPC
and active-active server NIC teaming. This scenario is supported only with the Cisco Nexus 5000 or 6000
Series Switches used as upstream switches. This scenario is not currently supported with the Cisco Nexus
7000 Series Switches.
●
vPC+: In this deployment scenario, access-layer redundancy is achieved through server vPC, fabric
extender vPC, and EvPC. In addition, a vPC+ domain allows the Cisco Nexus parent switch and the fabric
extenders to be viewed as a single virtual switch in a Cisco FabricPath network.
Figure 7. Cisco Nexus 2000 Series Fabric Extenders Design Scenarios, from Left to Right: Server vPC, Fabric Extender vPC,
EvPC, and vPC+
All topologies are supported with Cisco Nexus 5000 and 6000 Series parent switches.
The Cisco Nexus 7000 Series supports server vPC and fabric extender vPC scenarios.
The Cisco Nexus 9000 Series supports the server vPC scenario.
