SUMMARY
Adding a Dell™ PowerConnect™ Blade (M-Series) switch, with a Dell PowerEdge™ M1000e
modular blade enclosure, to an external PowerConnect™ J-Series Switch is a straightforward
process. The addition of Simple Switch Mode on the Dell PowerConnect™ Blade switch further
simplifies the process, allowing integration into existing network with minimal effort. This
document is part of Simple Connect campaign that includes both Simple Connect for SAN and
Simple Connect for LANs – both targeted at today’s FC SAN and Ethernet LAN environments and
meant to serve as a supplement guide on how to interconnect equipment that makes up
datacenter.
The Dell PowerConnect™ J-Series product family delivers open and flexible solutions for
datacenters and enterprise networks, based on technology from and collaborating with Juniper
Networks. This document provides an easy to use, step by step, guide on how to configure and
deploy DELL™ M-Series 10Gbit/s Blade Switch (M8024) (see Figure 1) with a DELL™ external
PowerConnect™ J-EX8200 Line of Switches.
Figure 1: The Dell PowerConnect™ M8024 switch
The PowerConnect J-EX8200 Series
The PowerConnect J-EX8208 modular Ethernet switch (See Figure 2), a member of the Dell
PowerConnect J-EX Series Ethernet Switches product family, offers a flexible, powerful, and
modular platform that delivers the performance, scalability, and high availability required for
today’s high-density data center, campus aggregation, and core switching environments. With a
total capacity of up to 6.2 Tbps, the EX8208 system provides a complete, end-to-end solution
for the high-performance networks of today and into the future.
_____________________________________________________________________________________ Deployment of Dell Blade Switches with an External J-Series Switches Page 4
The PowerConnect J-EX8200 series of Ethernet switches exhibit five key characteristics that,
working together, deliver a true enterprise switching solution:
High Reliability: Nothing succeeds like success. That’s why the PowerConnect J-EX8200
Series Ethernet Switches utilize much of the same established technology—including
high-performance application-specific integrated circuits (ASICs), system architecture
and Junos operating system—that power some of the world’s largest networks. The
result is a robust, time-tested and highly reliable network infrastructure solution for
high-performance enterprises.
Security Risk Management: The PowerConnect J-EX8200 Series Ethernet Switches are
fully compatible with the Unified Access Control (UAC), delivering an extra layer of
security by first authenticating users and performing virus checks, then enforcing
precise, end-to-end security policies that determine who can access what network
resources, as well as quality of service (QoS) policies to ensure delivery of business
processes. Integrated anomaly-based threat detection provides additional protection by
being able to identify and block distributed denial of service (DDoS) attacks.
Network Virtualization: The J-EX8200 Series switches support hardware based generic
routing encapsulation (GRE) tunneling for sending mirrored traffic from remote
locations to monitoring devices in the network operations center for centralized
troubleshooting and analysis, or to build segregated overlay networks without the
challenges associated with Spanning Tree.
Application Control: Successfully managing a network requires knowing how it’s being
used in order to optimize application delivery and maximize efficiency. Integrated high-
performance ASICs on the chassis-based J-EX8200 series of Ethernet switches provide
wire-like speed forwarding for any and all packet sizes. To ensure application traffic is
properly prioritized, the J-EX8200 Series Ethernet Switches support a robust eight QoS
queues per port—more than enough to establish separate queues for control plane,
voice, video and multiple levels of data traffic, with room to converge other networks
such as building automation and security cameras.
Lower TCO: A highly scalable pay-as-you-grow architecture, network designs with lower
power consumption, space and associated cooling requirements, a common operating
system, and unified management tools across the J-Series portfolio all combine to help
reduce operational and capital expenses for J-EX8200 Series Ethernet Switch customers.
The high-performance, high-density platforms let users start small and grow
incrementally, saving valuable space in crowded wiring closets and data centers while
_____________________________________________________________________________________ Deployment of Dell Blade Switches with an External J-Series Switches Page 5
lowering recurring power and cooling costs. Using a common version of the Junos
operating system across the switch families helps ensure consistency throughout the
infrastructure and accelerates the learning curve. And unified management tools
consolidate system monitoring and maintenance, saving time and money. Working
together, these J-EX Series switch attributes help advance the economics of networking
by allowing businesses to spend less money and time on their network infrastructure—
and more on innovative technologies that help them gain a competitive edge
The PowerConnect J-EX8208 is designed for Enterprise and Public customers of all sizes. The J-
EX8208 switch is optimized for both data center and campus aggregation and core.

Simple Switch Mode
Simple Switch Mode, or SSM, allows server administrators, or anyone with very limited
expertise in configuring Ethernet Switches, the ability to deploy a loop-free switching solution
without having to configure the Spanning Tree Protocol (STP) or design its integration into the
existing environment.
The primary advantages of deploying SSM are as follows:
Port Aggregation is easy to configure. Simply group internal ports and associate with external ports, assign VLANs (if required), and it’s ready to go.
SSM automatically configures multiple external ports into a Link Aggregation Control Protocol (LACP) trunk group.
By using Aggregator Groups, the feature provides loop-free operation without using STP. Port Aggregation is completely interoperable. Dynamic (via LACP) and static link
aggregation is supported on the external ports.

TESTING SCENARIOS
This document presents an overview of variety of different network deployment scenarios and
then provides step by step set up guide using configuration tools with screen shots as visual
guide. Intent of the paper is to show how some of the built in features like Simple Switch
firmware can be used to easily and quickly configure both equipment to work with each other
without requiring extensive knowledge of network.
In the sections that follow, we discuss some of the new features of the hardware and software,
give an overview of the deployment process, and present the following eight sample scenarios:
Scenario 1: Plugging and playing the Dell PowerConnect M8024 switch
In this section, we provide an overview of the plug-and-play process with the Dell
PowerConnect M8024 switch, by configuring Link Aggregation Control Protocol (LACP) on J-
EX8208 switch ports. Dell’s plug-and-play features with Simple Switch Mode allow for quick
integration of a new Dell switch into a network. We provide detailed instructions in Appendix A.
1. On the J-EX8208 switch, configure LACP on “ae0” Link Aggregation Interface.
2. Assign an IP address to “ae0” interface.
3. Create a device count, which represents how many aggregated interface (port channel
group) are functional.
4. Connect the cables from the J-EX8208 Blade switch to the Dell PowerConnect M8024
switch. The Dell PowerConnect M8024 switch will automatically create an aggregate group
and establish network connectivity.

Scenario 2: Configuring VLANs on the internal ports of the Dell PowerConnect
M8024 switch
In this section, we provide an overview of configuring the VLANs on the internal ports of the
Dell PowerConnect M8024 switch, while configuring those on the J-EX8208. VLANs allow for
greater granularity and quality of service (QoS) control over simple sub-netting, and Dell
switches with Simple Switch Mode enabled offer quick and easy VLAN configuration. We
provide detailed instructions in Appendix A.
1. On the Dell PowerConnect M8024 switch, enter the Internal Port VLAN configuration
screen, select a port, and change the default Untagged VLAN (we changed port 1/xg1 to
VLAN 101).
2. On the J-EX8208 switch, create a two-port channel group with LACP and trunking enabled.
3. Allow VLAN 101 through the new port channel.
4. Connect the cables. The Dell PowerConnect M8024 switch will automatically make a four-
port LAG and tag all communications from the designated internal port as VLAN 101.

Scenario 3: Configuring multiple VLANs per internal port to connect to a server
NIC with Tag enabled
In this section, we provide an overview of configuring multiple VLANs per internal port to
connect to a server NIC with Tagging enabled, which is useful for management of VMs. We
provide detailed instructions in Appendix A.
1. On the Dell PowerConnect M8024 switch, enter the Internal Port VLAN configuration
screen, select a port, and add several Tagged VLANs (we changed port 1/xg6 to include
VLANs 2-3).
2. On the J-EX8208 switches, create a two-port aggregation group on “ae0” interface and
trunking enabled.
3. Allow VLANs 2-3 through the new aggregation group (port channel).
4. Connect the cables. The Dell PowerConnect M8024 switch will automatically make a two-
port LAG. From now on, you can modify VM communications so that you can tag them to
various VLANs.

Scenario 4: Configuring multiple Port Aggregation Groups and dedicating
specific Uplinks
In this section, we provide an overview of configuring multiple Port Aggregation Groups
(AGs to group specific attached blade servers) and dedicating specific Uplinks to carry that
traffic to the J-EX8208 witch network. Doing this allows us to physically separate traffic for
easier administration. We provide detailed instructions in Appendix A.
1. On the Dell PowerConnect M8024 switch, enter the Port Configuration screen, and change
the group ID of the ports you desire to Group 2 (we changed ports 1/xg14 and ports 1/xg21-
1/xg22 to Group 2).
2. On the J-EX8208 switch, create two two-port aggregation groups (ae0 & ae1) with LACP
enabled.
3. Connect the cables. The Dell PowerConnect M8024 switch will automatically make two two-
port LAGs, separating the traffic from between the two groups created earlier.

Scenario 5: Adding VLANs in a multi-AG configuration
In this section, we provide an overview of adding VLANs in a multi-AG configuration, which
combine the advantages of virtual network administration with physical network separation.
We provide detailed instructions in Appendix A.
1. On the Dell PowerConnect M8024 switch, enter the Port Configuration screen, and change
the group ID of ports to Group 2 (we changed ports 1/xg14 and ports 1/xg21-1/xg22 to
Group 2).
2. Enter the Internal Port VLAN configuration screen, select a port, and add several Tagged
VLANs (we changed port 1/xg6 to include VLANs 2 and port 1/xg14 to include VLANS 3).
3. On the J-EX8208 switches, create two two-port channel groups with LACP enabled.
4. Connect the cables. The Dell PowerConnect M8024 switch will automatically make two two-
port LAGs, separating the traffic from between the two groups created earlier.

Scenario 6: Setting up a straight-through topology with LAG failover
In this section, we provide an overview of setting up a straight-through topology with LAG
failover. Simple Switch Mode LAG failover allows Dell switches to automatically change from
the primary to the backup LAG in the event of a port failure, reducing potential downtime. We
provide detailed instructions in Appendix A.
1. On the Dell PowerConnect M8024 switch, enter the Port Configuration screen, and change
the Lag Role of ports to Secondary (we changed ports 1/xg23-1/xg24 to Secondary).
2. On the J-EX8208switches, create two two-port channel groups with LACP enabled.
3. Connect the cables. The Dell PowerConnect M8024 switch will automatically make a two-
port LAG with a secondary backup LAG that it will failover to in the event of a cable or port
failure.
