Deployment of Dell M6348 Blade Switch with Cisco 4900M Catalyst Switch Page 5

TESTING SCENARIOS

In the sections that follow, we present an overview of a variety of different network

deployment scenarios and then provide step-by-step set up guidence using configuration

tools with screen shots as a visual guide. 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.

Scenario 1: Plug and Play the Dell PowerConnect M6348 Switch

In this section, we will setup a basic network connection between the PowerConnect M6348

blade switch and the Cisco Catalyst 4900M to allow a Dell blade server to connect to the

Cisco Catalyst through the PowerConnect M6348.

By default, all internal ports and the first 8 external ports of a PowerConnect M6348 are in

port-aggregator group 1, but this can be changed by the user. All ports (internal and external)

within a port aggregator group can communicate. There is a maximum of 8

external

ports

in any port-aggregator group. 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 in a LAG (link aggregation group). Secondary LAG roles are for backup LAGs in

case of a LAG failure.

External ports don’t need to be side by side to be in the same port aggregator group.

For example, ports 33 and 40 can be in group 1 and ports 34 and 35 can be in group

2. Having multiple external Ethernet ports of different speeds (e.g. 1G and 10G) in the

same LAG is not supported, however they can be in the same port-aggregator group

as long as one speed is used as a primary LAG and the other as a secondary (backup)

LAG. All ports in a port-aggregator group only go to a single destination, which

eliminates the need for STP.

Upstream switches should have port-fast enabled on any links connected to an

external port of an M6348 while in Simple Mode. Internal ports of an M6348 are not

active unless there is at least one active external connection.
