Stacking Dell Force10 MXL 10/40G Switches13For this example the built-in ports 33 and 37 and the expansion ports 41 and 45 are used as shown inthe above figure.For each switch in the stack, two cables are run from stacking ports on a switch to the two stackingports on the next switch. This process is repeated until all of the devices are connected. To completethe ring topology for the stack, two stacking ports on the last switch are connected to two stackingport on the first switch.Connecting additional cables in parallel will increase the stacking bandwidth. Dell recommends thatyou connect the stack in a ring topology for resiliency and also that you use the same number of portsbetween peers in the stack. For example, do not use two cables between switches 1 and 2, and 2 and3, but then only one cable to connect 3 and 1.Note: Up to four ports per MXL can be used to create a stack. All four ports on a member could beconnected in parallel to another stack peer to create a stack of two members. Three ports could alsobe used in parallel to create a stack with only two members. To create a stack with three or moremembers, use 1 or 2 links between each member.Creating the MXL stackPrepare individual switches to be stacked1. Identify all switches to be used as members of the stack, and upgrade each (as standalone MXL10/40GbE switches) to the same firmware version.2. Each MXL switch should be powered up with the default configuration.3. Once the initial switch configuration is complete and the individual MXL 10/40GbE switches arepowered up and fully operational, they are then ready to be stacked using the instructionsbelow.Each 40GbE Interface corresponds to a stack-group, which is shown in the output of "show systemstack-unit 0 stack-group" command. Use the “show inventory optional-module” command to see whatexpansion modules are installed.Example:FTOS#show system stack-unit 0 stack-groupStack group Ports------------------------------------0 0/331 0/374 0/495 0/53FTOS#show inventory optional-moduleUnit Slot Expected Inserted Next Boot Power-----------------------------------------------------------------0 0 SFP+ SFP+ AUTO Good0 1 QSFP+ QSFP+ AUTO Good
