Overview
Ruckus Campus Fabric technology integrates high-performance, xed-form-factor switches to create a single distributed logical
switch that is independent of physical location and that allows organizations to add ports across the campus whenever and
wherever needed without adding complexity. Traditional three-tier network designs with a "big-box" chassis at the aggregation
and core layers require a signicant up-front investment, but with Ruckus Campus Fabric, switches can be added when needed
and they still perform like one big switch. Switch Port Extender, abbreviated as SPX, is the name of this Campus Fabric solution.
ATTENTION
The SPX architecture simplies network management by unifying core, aggregation, and access functions. A core stack
(distributed chassis) serving as the control bridge connects to downstream Switch Port Extender (PE/SPX) units that
aggregate large numbers of access devices. Switch Port Extender creates a more scalable architecture based on IEEE
802.1BR standards.
Advantages of the SPX architecture:
• A centralized point of control and management
• IEEE 802.1BR open-standard-based solution
• STP-free Layer 2 design
• Policy and feature inheritance
• Scale-out using xed switches
The following devices from the Ruckus ICX product family support SPX congurations in FastIron 08.0.50 and later releases:
• Ruckus ICX 7250 Switches (ICX 7250): port extenders
• Ruckus ICX 7450 Switches (ICX 7450): port extenders
• Ruckus ICX 7750 Switches (ICX 7750): control bridge
NOTE
The Ruckus ICX 7250 and ICX 7450-ZP switches are not supported as port extenders in FastIron 08.0.40.
NOTE
The Ruckus ICX 7250-24G switch cannot be used as a PE unit in FastIron 08.0.50.
NOTE
The Ruckus ICX 7150 switch is supported as a port extender in FastIron 08.0.70 and later.
The Ruckus ICX 7750 is a powerful stackable switch that enables simplied distributed chassis deployments for the scale-out
campus aggregation and core networks; helping organizations seamlessly add network capacity in an agile, cost-ecient
manner.

Part Number: 53-1004186-03 5
Preface
Purpose of This Document
The Ruckus ICX 7250 and ICX 7450 switches deliver the performance, exibility, and scalability required for enterprise gigabit
Ethernet access deployment. These switches oer market chassis-level performance and reliability with the exibility, cost-
eectiveness, and "pay as you grow" scalability of a stackable solution.
The components of the Ruckus SPX architecture are the Ruckus ICX 7250 and ICX 7450 routers congured as port extenders
(PEs), or PE units, to a set of Ruckus ICX 7750 stack units congured as the 802.1BR control bridge. The ICX 7750 control bridge
(CB) provides a single point of management for the extended network. Active and standby controller functions are retained in the
ICX 7750 (control bridge) stack and continue to provide hitless recovery and extended administrative functions. SPX widely
increases the number of access devices in the network that can be controlled and managed from a single point. The distributed
CB at the center of the SPX architecture manages PE units and hundreds of ports at the network edge.

SPX Technical Architecture
• Control Bridge................................................................................................................................................................9
• Port Extenders............................................................................................................................................................... 9
Control Bridge
The control bridge (CB) manages port extender (PE) units. It performs switching, routing, and forwarding for PE ports and
provides centralized policy management. The CB uses the Link Layer Discovery Protocol (LLDP) to discover PE units. When the CB
discovers a PE unit, it connects to the PE unit and creates a control plane using Control and Status Protocol (CSP) over the uplink/
cascade port. Each PE port is managed as a virtual port from the CB perspective. The CB sets up each PE unit for trac
forwarding and creates multicast and unicast forwarding tables through CSP.
The Ruckus ICX 7750 acts as control bridge. The control bridge can be a standalone device or a stack. The control bridge stack
can have a maximum of four units with a ring or linear topology. The ICX 7750 supports long-distance stacking spanning up to 10
kilometers between stack units.
Refer to Bill of Materials on page 23 for qualied optics and port combinations supported for long-distance stacking on the ICX
7750.
The models of the ICX 7750 have a similar hardware design. The dierences lie mostly in the external interfaces. All models
support the 802.1BR standard. The ICX 7750 has the following models:
• ICX7750-48F
• ICX7750-48C
• ICX7750-32Q
Port Extenders
The port extenders (PEs) provide a data path between end hosts and the control bridge and use LLDP to advertise 802.1BR
capabilities to the CB over the upstream port or LAG. If capabilities match, the PE uses CSP to attach to the CB. The PE reports the
number of available ports to the CB, and the CB allocates an ECID for each PE port. The PE units perform hardware-based
multicast and broadcast replication.
The Ruckus ICX 7250 and ICX 7450 act as port extender units, which are managed by the control bridge. All ICX 7150 models can
be congured as PE units beginning with FastIron 08.0.70 and later.
PE units rely on the CB for most network functions.
The ICX 7450 has six dierent models based on port density, PoE capability, and port type; in addition, each of the models
supports four dierent ex modules. The ICX 7450 has the following models:
• ICX7450-24
• ICX7450-24P
• ICX7450-48
• ICX7450-48P
• ICX7450-48F

connections.
NOTE

Scaling (Supported Topologies)
ATTENTION
Use port extender ports to hook to APs, phones, and PoE devices. Use control bridge ports to connect to servers, VMs,
and so on.
Do not hook the PE ports to any other routers and switches. Do not deploy where compact switches are connected to
the PE ports where the compact switches are not part of the Campus Fabric, but standalone units.
Disable LLDP on user ports where it is not required for the FastIron system to scale, and avoid high CPU issues.
Turn o FDP and CDP in scaled environments.

Deployment Considerations
• SPX LAG or port: Only one SPX LAG or SPX port is allowed between the CB and the PE or between the PE and the PE.
• Speed: No speed negotiation is possible when SPX links are congured.
• VLANs: 4 VLANs per PE port (including the default VLAN). A maximum of 16 VLANs for 128 PE ports.
• STP: If Spanning Tree Protocol is enabled on the CB, a reload is required.
• IP addressing: No IP addressing on the physical PE port (only VEs are supported).

Conguration Notes
• An ICX 7750 traditional stack or a standalone ICX 7750 device can be enabled as an 802.1BR control bridge (CB).
• A traditional stack that serves as a CB stack in an SPX domain should contain no more than four units.
• A CB can be a ring or linear stack or a standalone unit.
• A CB stack can be formed using Module 2 or Module 3 ports on all models.
• A CB-to-PE link can be 10G or 40G.
• A PE-to-PE link can be 1G, 2.5G, 10G, or 40G.
• A CB stack can be formed with a secure setup utility or by manual conguration. (For more information, refer to the
Ruckus ICX 7450, ICX 7750, and ICX 7250 Stacking Deployment Guide.)
• The CB unit ID ranges from 1 to 12.
• PE IDs range from 17 to 56.
• For manual bring-up, you must establish console sessions to all standalone ICX 7450 units and ICX 7250 units before
bringing them up as SPX PEs. Once the SPX fabric is up, all functionality can be managed from the CB active unit's
console, SSH, or Telnet session.
• You should use ZTP to deploy the SPX domain. Refer to Zero-Touch Provisioning on page 85 for more information.

Conguring the CB
1. Enable SPX on the ICX 7750.
• Congure spx cb-enable on the active CB unit. The spx cb-enable command adds "lldp run" to the running
conguration in FastIron 08.0.40 and earlier. LLDP then runs on all CB ports.
• If STP is enabled, the system must be reloaded.
• If STP is enabled in the core, a reload is prompted once the CB is enabled.
ICX7750-48F Router(config)# spx cb-enable
System is now in 802.1br Control Bridge (CB) mode. Add "lldp run" config.
2. Congure the SPX port or the SPX LAG on the CB.
Enter the spx-port or spx-lag conguration command for connecting the CB to the PE.
NOTE
PE units can join an SPX domain only after at least one working SPX port or SPX LAG has been congured on
both the CB and the PE.
ICX7750-48F Router(config)# spx cb-configure
ICX7750-48F Router(config-spx-cb)# spx-lag 1/1/1 1/1/2
ICX7750-48F Router(config-spx-cb)# spx-lag 1/2/6 2/2/6 3/2/6
