Preface

Today's campus networks are critical for business connectivity to customers, vendors, and partners

and to support the latest enterprise applications, cloud-based services, and mobile users' access to

the network. The campus networks of today and tomorrow should be flexible, easy to manage, and

cost-effective. The Effortless Network™ is the Brocade vision to meet these objectives; the Brocade

HyperEdge Architecture is the cornerstone for delivering on that vision.

Three key design principles drive the development of the Brocade HyperEdge Architecture for

modernizing and simplifying the network:

1. Consolidated management: Reduces unnecessary network layers to create large HyperEdge

management domains that eliminate individual switch touch points to ease maintenance time and

costs.

2. Shared network services: Allows premium and entry-level switches that share a common

HyperEdge management domain to share advanced L2/L3 services to achieve lower price per-port

functionality.

3. Scale-out networking:

Integrates high-performance fixed form factor switches to create a single logical device independent

of physical location by scaling ports when and where needed across the campus.

HyperEdge architecture implementation options: Brocade offers multiple implementation options to

achieve the benefits of the HyperEdge Architecture design principles

• The Mixed Stack design integrates premium and entry-level Brocade ICX switches that collapse

the network access and aggregation layers into a single HyperEdge domain that shares services

while reducing management touch points and network hops.

• The Distributed Chassis design integrates high-performance 10 GbE/40 GbE Brocade ICX

stackable switches that collapse the network aggregation and core layers into a single HyperEdge

domain with the density and reliability of large chassis switches at a fraction of the cost, while

putting ports where needed on the campus.

HyperEdge Distributed Chassis Design: The Distributed Chassis feature leverages the capability to

combine up to 12 Brocade ICX 7750 Switch units in a single logical switch spread across the campus.

This distributed chassis offers a level of flexibility, ease of deployment, and total cost of ownership

unmatched by traditional aggregation and small-core chassis solutions. Due to rapid technology

evolution and innovative development, Brocade is able to offer the first 10 GbE/40 GbE stackable

solution for the campus aggregation and core layers that delivers higher performance and port density

than a traditional mid-size chassis, while offering the same level of reliability and availability. Brocade

offers a truly distributed architecture, where all the components can be spread across the entire

Brocade ICX 7450, Brocade ICX 7750, and Brocade ICX 7250 Stacking

campus-due to the use of long-distance optical links-yet, the whole system can be managed as a single

entity.

Overview

The Brocade ICX 7450, Brocade ICX 7250, and Brocade ICX 7750 are high density 1RU switches that

can run switch or router code to provide full L2 and L3 functionality. They come in five different

hardware SKUs .

The Brocade ICX 7450 switch delivers the performance, flexibility, and scalability required for

enterprise Gigabit Ethernet (GbE) edge deployment. It offers market-leading stacking density with up to

12 switches (576 1 GbE and 48 10 GbE ports) per stack and combines chassis-level performance and

reliability with the flexibility, cost-effectiveness, and "pay as you grow" scalability of a stackable

solution .

The Brocade ICX 7750 is a 1U fixed form factor 10/40 GbE Ethernet switch delivering a chassis

experience for campus LAN aggregation and core. It offers market-leading port density and chassis-

level performance, availability, and scalability. The Brocade ICX 7750 Distributed Chassis stacking

technology enables scale-out networking.

The Brocade ICX 7250 switch delivers the performance, flexibility, and scalability required for

enterprise Gigabit Ethernet (GbE) edge deployment. It offers market leading stacking density with up to

12 switches (576 1GbE and 96 10GbE ports) per stack and combines chassis level performance and

reliability with the flexibility, cost-effectiveness, and "pay as you grow" scalability of a stackable solution.

ICX 7450 Stacking

With Release 08.0.20, the Brocade ICX 7450 supported stacking only on 1x40G modules. With

Release 08.0.30, the Brocade ICX 7450 supports stacking on 4x10G modules as well.

NOTE

The ICX 7450 can support 4X10 GF stacking from slot 2 or 1x40GQ stacking from rear ports;

however, it cannot support both in the same stack.

ICX Stacking with 1x40G Ports

Stacking is supported only on 1x40Q module when placed in rear modules 3 and 4 for 24 ports and 48

port SKUs. For 24 port units, 1x40Q module is supported in all three flexible module slots which are

Modules 2, 3 and 4; but it will not support stacking when present in slot 1. For 48 port units, 1x40Q

module is supported only on slots 2 and 3. Please refer to Table 1 for more details.

When stacking enabled, the two stack ports configured by default are 1/3/1 and 1/4/1. The following

figure shows default stacking ports for ICX7450.

53-1003581-03

NOTE

When stacking is not enabled, ports x/3/1 and x/4/1 can be used as data/uplink ports.

FIGURE 6 ICX 7450 Showing 1x40G Stacking Ports

ICX Stacking with 4x10G Ports

Stacking is supported on 4x10GF modules when placed in front module 2 for 24 ports and 48 port

SKUs. 4x10GF module can be supported in slot 3 and 4 of all SKUs but stacking on 4x10GF module is

supported only when present in module 2. Please refer to Table 1 for more details.

Since default stacking ports are 1/3/1 and 1/4/1, user has to use "default-ports 1/2/1 1/2/3" command to

change default stacking ports to 4x10GF ports. With 4x10GF ports, comes support for stack trunks.

Trunk can be x/2/1 to x/2/2 and x/2/3 to x/2/4. Each trunk must have a default stacking port configured

as first trunk port. The figure below shows 4x10GF ports available for stacking.

NOTE

When stacking is not enabled, ports x/2/1 and x/2/3 can be used as data/uplink ports.

FIGURE 7 ICX 7450 Showing 4x10G Stacking Ports

Stack can be formed using up to 12 units of any ICX 7450 model type as a liner topology or a ring

topology.

Supported Topologies

The Brocade ICX 7450 can operate as a standalone device as well as a stackable device. When used

as a stack, ICX 7450 supports linear and ring stack topologies. All different SKUs of ICX 7450 can be

mixed in the same stack. The stack can be formed with two units and up to twelve units. Following are

examples of some of the ICX 7450 stacks connected in linear and ring topologies using 1x40G

stacking ports.

NOTE

The Brocade ICX 7450 cannot be combined in a stack with other Brocade stackable devices.

2 unit stack linear and ring topology

NOTE

The Brocade ICX 7450 does not support trunking on 1x40G stack ports. For the two unit ring topology

shown above, the stack ports x/3/1 and x/4/1 on each unit cannot be used to form one trunk; they

should be individual stacking ports.

4 unit stack linear and ring topology
