Deployment of Dell M8024-k Blade Switch in Simple Mode with Cisco Nexus 5k Switch Page | 2 Summary Adding a Dell™ PowerConnect™ blade (M-Series) switch, with a Dell PowerEdge™ M1000e modular blade enclosure, to an external Cisco Nexus 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 the 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. 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-k) (see Figure 1) with a Cisco Nexus 5020 Switch Figure 1. The Dell PowerConnect M8024-k switch 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 Simple Switch Mode 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. To enable Simple Switch Mode on a Dell PowerConnect M8024-k switch, perform the following steps via Command Line or Web Interface: Command-Line Interface: To enable simple mode on a M8024-k switch, follow the below: 12 34 CONSOLE PowerConnect M8024-k 17181920

Select System Operational Mode Configuration. In the Configuration screen, select Enable in the Simple Mode drop-down menu, and left-click Apply (see Figure 2). Figure 2.

Testing Scenarios
The following sections will present an overview of a variety of different network deployment
scenarios and will provide step-by-step set up guidance using configuration tools with screen shots
as a visual guide. The intent of the paper is to show how some of the features of Simple Switch
firmware can be used to easily and quickly configure both equipment to work with each other
without requiring extensive knowledge of network.
Each of the following scenarios in this document assume you are starting with a default
Simple Mode configuration and (by default) ports Te1/0/1 through Te1/0/20 are currently
members of Port Aggregator Group 1.
All scenarios assume the M8024-k is using external ports 17-20 and that no module is installed
providing additional external 10G ports.
Scenario 1: Plug and Play the Dell PowerConnect M8024-k switch
This scenario shows a basic network setup between the PowerConnect M8024-k switch and the
Cisco Nexus 5020. Figure 3 shows this connectivity.
By default, all internal ports and the first 4 external ports of a PowerConnect M8024-k are in port-
aggregator group 1. This configuration can be easily changed by the user at any time. All internal and
external ports within the same port aggregator group can communicate with each other. When one
or more cables are plugged into external ports of the same port-aggregator group and in the same
LAG role (primary or secondary) they are automatically joined in a LAG (link aggregation group).
Secondary LAG roles are for backup LAGs in case of LAG failure.
All ports in a port-aggregator group only go to a single destination, which eliminates the
need for STP.
Upstream switches using STP should have port-fast enabled on any links connected to an
external port of an M8024-k while in Simple Mode. Internal ports of an M8024-k are not
active unless there is at least one active external connection.
Deployment of Dell M8024-k Blade Switch in Simple Mode with Cisco Nexus 5k Switch Page | 5 Figure 3. Graphic representation of Scenario 1 Configuring the Dell M8024-k Switch The only necessary configuration on the M8024-k switch side is to put the switch at Simple Switch mode. This procedure was explained at the pervious sections. Configuring the Cisco 5020 Switch Configure Link Aggregation Control Protocol (LACP) on Cisco switch ports. In this example, the first 4 ports of Cisco Nexus which are connected to M8024-k switch need to be configured as one single aggregation group. To do so, login to Cisco Nexus 5020 and follow the below changes: Nexus5020#config Nexus5020(config)#feature lacp Nexus5020(config)#interface ethernet 1/1-4 Nexus5020(config-if-range)#channel-group 1 mode active Nexus5020(config-if-range)#exit Nexus5020(config)#exit `STAT CONSOLE L1 L2 MGMT 0 MGMT 1481216 371115 261014 15913 20242832 19232731 18222630 17212529 SLOT2 3438 3337 3640 3539 SLOT3 Cisco Nexus 5020 PS1 PS2 200-240v-6A50~60Hz Dell M 1000 e Blade Enclosure M 8024 -K 1 2 3 4 Cisco Nexus 5020 Single LAG B2C2A2B1C1A1417528639CMC2CMC1KVM123456 GbGb21CMC iKVM GbGb21CMC 12 34 CONSOLE PowerConnect M8024-k 17181920
Deployment of Dell M8024-k Blade Switch in Simple Mode with Cisco Nexus 5k Switch Page | 6 Scenario 2: Configuring an untagged VLAN on a single LAG This scenario shows an overview of configuring VLANs on the internal ports of the Dell PowerConnect M8024-k switch. Figure 4 shows this connectivity. VLANs allow for greater granularity and quality of service (QoS) control over simple sub-netting, and Dell switches with Simple Switch Mode enabled offer a quick and easy VLAN configuration. In this example we will configure VLANs across the internal ports of the M8024-k and then extend these VLANs into the external network by configuring the Cisco Nexus switch. Figure 4. Graphic representation of Scenario 2. Configuring the Dell M8024-k Switch Command-Line Interface: Command-line interface for configuring the Dell M8024-k switch is as follow: console(config)#port-aggregator group 1 console(config-portAggr-group-1)#interface tengigabitethernet 1/0/1 console(config-portAggr-if-Te1/0/1)#switchport general allowed vlan add 100 untagged Warning!

Select any port from the Internal-Port menu. For this example we chose port Te1/0/1. Enter a VLAN number, i.e. 100, in the Untagged-VLAN field (Figure 5). Figure 5. Web Interface for the Dell M8024-k Switch for Scenario 2. Click Apply. Configuring the Cisco 5020 Switch Login to the Nexus 5020 and make the following changes: Nexus5020# configure Enter configuration commands, one per line. End with CNTL/Z.

As an example, to assign an IP address to VLAN interface on Cisco Nexus use the following commands: Nexus5020(config)# feature interface-vlan Nexus5020(config)# interface vlan 100 Nexus5020(config-vlan)# ip address 10.1.1.100/16 Nexus5020(config-vlan)# no shutdown Nexus5020(config-vlan)# exit
