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

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.

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.

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.

Stack construction method 1: Stack secure setup

Description

'Stack secure setup' utility is the most convenient of all methods to form a stack. This utility uses a Brocade proprietary discovery protocol that discovers units that are connected upstream and downstream from the switch where this command is entered, the intended Active controller.

Steps

Stack formation with secure setup utility:

• Configure 'stack enable' on the intended active controller unit at configuration level.

• Enter 'stack secure setup' on the intended active controller unit at device level.

Detailed steps:

1. Select a unit that you want to become an active controller. Configure 'stack enable' at configuration level as seen in the following logs.

ICX7450-24 Router#configure terminal ICX7450-24 Router(config)#stack enable Enable stacking. This unit actively participates in stacking stacking is enable. optical monitoring for stacking ports 1/3/1, 1/4/1 is not available. ICX7450-24 Router(config)#

2. Once stack enable is configured, this command will configure two default stack ports, 1/3/1 and 1/4/1 as seen in the message displayed. This can be confirmed using 'show run' command.

ICX7450-24 Switch(config)#show running Current configuration: ! ver 08.0.20T213

stack mac cc4e.246c.e100 ! !!

3. Enter 'stack secure setup 'at device level, this command triggers a Brocade proprietary discovery protocol that begins the discovery process in both upstream and downstream directions. The discovery process produces a list of upstream and downstream devices that are available to join the stack. This process will assign switch IDs to the units. During stack formation user will be prompted to enter desired number of units either upstream or downstream depending on the connections. In the following example 11 units are discovered downstream.

NOTE

During the secure-setup process, after one minute of inactivity, authentication for stack members expires, forcing you to restart the process .

NOTE

To exit the secure-setup, enter Control-C (^C) at any time.

6. While stack formation, units go through various stages when they joins the stack. Once units become part of the stack and the master syncs relevant information and files to all the units and then they are set in "READY" state. During the process the user is prompted to 'write memory' to save changes.

Stack construction method 2: Manual configuration

Description

With this method, user should configure every unit individually and enable stacking on each unit. Once the units are connected together, they automatically form a stack. With this method, the unit with the highest priority becomes the active controller, and ID assignment is determined by the sequence in which user physically connects the units. The example used below is 12 units to form a linear stack.

Steps

Manual stack formation:

• Configure the highest priority on an intended active controller.

• Configure second highest priority on an intended standby controller.

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

• Configure 'stack suggested-id' on the units that will have a desired ID.

• Configure 'stack enable' on all the units and connect the units using stack ports.

Detailed steps

1. Units should boot up using the same software image.

2. On the unit that is intended to be the active controller, configure priority 255. On the unit intended to be on standby, configure priority 240. User can choose to have the same priority for active and standby, which is useful in case of failover.

3. Since each unit is a clean unit, its unit id is 1. Enter 'configure terminal', enter 'stack unit 1' and configure 'stack suggested-id' on all the units that will have the desired ID.

4. Configure 'stack enable' on all the units.

5. After configuration, connect the devices in a stack topology. The active controller retains its ID. The rest of the units are assigned unique ID numbers depending on the sequence in which they are connected or depending on the stack suggest-ID configured. With the exception of the active controller, the rest of the units reset; upon boot up, the stack is formed.

Brocade ICX 7450 Stack Construction Methods with 4x10G Stacking Ports

Two ways of constructing a stack are as follows:

1. Use the 'secure setup' utility to form the stack.

2. Manual stack formation where each unit is configured individually.

Topology

The figure below shows the rear of three units connected in a linear topology using stack trunks. Similarly, a stack of up to 12 units can be connected. The example presented here for configuration is for a 12-unit stack. Please refer to Bill of Materials, table 2 and table 3 for the software image, optics and vendor information.

• Configure 'default-ports 1/2/1 1/2/3' on all the units, write memory and reload. This step is needed because mac-sec and stacking cannot exist at the same time on a port.

• When units boot up, configure 'stack enable' on the intended active controller unit at configuration level.

• Enter 'stack secure setup' on the intended active controller unit at device level.

Detailed Steps

1. Select a unit that you want to become an active controller. Configure 'default-ports 1/2/1 1/2/3' on all the units, write memory and reload

NOTE

During the secure-setup process, after one minute of inactivity, authentication for stack members expires, forcing you to restart the process.

NOTE

To exit the secure-setup, enter Control-C (^C) at any time.

5. While stack formation, units go through various stages when they joins the stack. Once units become part of the stack and the master syncs relevant information and files to all the units and then they are set in "READY" state. During the process the user is prompted to 'write memory' to save changes.
