Stacking Dell PowerConnect Switches: 8132, 8132F, 8164, 8164F 11 Stacking scenarios The following sections present examples in a variety of areas concerning stacking the Dell PowerConnect 8100 switches and provides step-by-step guidance using the CLI and Web UI, with screen shots as a visual guide. Consult the table of contents above for a list of examples covered in this document. Each scenario in this document assumes that all Dell PowerConnect devices are using the same firmware revision. It is also recommended that all devices are using the latest firmware version. Note: Upgrade the firmware to the latest revision on the units before stacking them. Unless mentioned otherwise, all scenarios below assume the switches are using the static ports that are hard-wired into the switches, and that no modules are installed providing additional ports. However, ports from an installed expansion module are supported and may be used for stacking. The following expansion modules are supported for stacking in the Dell PowerConnect series:

With an expansion module installed, the command show switch stack-ports shows the link status, link speed, and stack mode for each port in the module. Creating a Stack Examples below provide steps on how to create a stack. Graphics shown in this section only depict some of the possibilities of how to cable together members of a stack. Note: While the cable pictures below come before the configuration steps, it is important not to cable the stack until instructed to do so. Cabling is one of the last steps and comes after configuring all switches used in the stack; however, it is necessary to know exactly each port that is going to be cabled to configure each switch correctly. The Dell PowerConnect 8100 series switches can be stacked up to six high, supporting up to 336x10G ports when two 40G ports on each unit are configured as stacking ports. The stack can contain any combination of Dell PowerConnect 8100 and Dell PowerConnect 8100F switches. The switches can be stacked using any Ethernet port on the front panel, which includes 40Gb QSFP+ ports, 10Gb SFP+ fiber ports, and 10Gb baseT copper ports. Each of these default to Ethernet mode and must be reconfigured as stacking ports in order to stack. This scenario shows steps to create a stack. Figure 8 shows one example of connectivity between stack members. 10GBASE-T MODULE LNKACT QSFP+ MODULEACT LNK ACT LNK 10G SFP+ MODULE LNKACT
Stacking Dell PowerConnect Switches: 8132, 8132F, 8164, 8164F 13 Stacking Dell PowerConnect 8100 series switches using 40G and 10G stack links Figure 8. Notice the top two switches are stacked together using four cables plugged into 10G ports. For each remaining switch in the stack, one cable from a 40G stacking port on a switch is connected to a 40G stacking port on the next switch. This process is repeated until all of the devices are connected. To complete the ring topology for the stack, one stacking port on the last switch is connected to a stacking port on the first switch. Things to consider when cabling a stack together: Only use interfaces with the same bandwidth to stack between members. It is not supported to mix 40G QSFP+ ports with 10G SFP+ or 10Gbase-T ports on a switch when stacking. It is okay however to use one interface type between two stack members, then a different interface type between two other stacking members as shown in Figure 8. A QSFP+ port is counted as one port when stacking. Therefore if stacking only two switches together, all QSFP+ ports (including those on an expansion module) can be used to stack between them when in 40G port mode. Up to eight ports may be used on any switch for stacking purposes. Connecting additional cables in parallel increases the stacking bandwidth. Up to eight ports can be connected in parallel when only stacking two switches. When stacking three or more switches, up to 4 cables can be connected in parallel between members. It is recommended to have the same bandwidth between the stack members. It is also recommended to connect the stack in a ring topology for resiliency. Figure 9 shows an example of connecting four stack ports between each stacking peer. Note: In a stack of three or more switches, Dell strongly recommends connecting the stack in a ring topology so that each switch is connected to two other switches.

QSFP+ quad-breakout cables
QSFP+ quad-breakout cables may also be used for stacking. This allows a 40G QSFP+ port to connect to
four 10G SFP+ ports on the adjacent switch. When a breakout cable is used, the connections are
considered to be four links taking up four ports.
QSFP+ quad-breakout cable may be used for stacking Figure 10.
To use a QSFP+ quad-breakout cable to stack two peers, the QSFP+ port must be set to port mode
4x10G and reloaded before setting it to stack mode (described in the next section). From the interface
configuration CLI prompt, use the hardware profile command to set the port to this mode. The
command is:
console(config-if-Fo5/0/1)#hardware profile portmode 4x10g
This command will not take effect until the switch is rebooted.
When the portmode changes on a port, so do the interface names. For example, a QSFP+ port may be
named Fo1/0/1 when in 40G mode but takes on a new identity as Te1/1/1 through Te1/0/4 when
changed to 10G mode. Therefore, if it is desired to use the QSFP+ quad-breakout cable, be sure to set
the port mode to 4x10G and reload the switch before setting the ports to stack mode since
configuration settings on one port mode does not translate to the other portmode.
Also, when in port mode 4x10G it is required that all four of the breakout ports be moved from
Ethernet mode to Stack mode to use them for stacking.

The Configured Stack Mode is now Stack, but the Running Stack Mode is still Ethernet. The Running
Mode changes to Stack upon reloading the switch, as instructed below.
Save the configuration to the Startup-Configuration.
console#copy running-config startup-config
This operation may take a few minutes.
Management interfaces will not be available during this time.

Perform the same steps for the remaining switches. Do not forget to configure the stacking ports on
the last and first switch to create a ring topology if desired. Once the switches have been configured,
remove power from all switches.
While powered off, cable all of the switches together using the stack ports that were configured.
Select the switch to be the Master switch and power up that switch only allowing a few minutes to boot
up completely. Verify the switch is up by logging into the CLI.
Once the Master is up, power up the next switch in line. Allow the second switch 30 seconds to boot
up, then power up the third switch. Continue to power up each switch allowing 30 seconds between
powering switches. This allows each adjacent switch to be active before the next one. Failure to wait
may result in another switch becoming the Master. All subsequent switches will enter the stack as
Member Units.
Stack Member units serial ports and management IP addresses are not accessible for managing those
devices. Only the Master’s management ports can be used to monitor and configure ports in the stack.
Validation
After the entire stack is created, it can be validated with the show switch command from the Master
switch:

The show switch stack-ports command can also be used to see all of the ports that have been added to
the stack as well as which ones are being used for stacking. To view only ports that are configured for
stacking, use the command show switch stack-ports | include Stack.
Figure 11 shows the Stack LED that is located on the back panel of every Dell PowerConnect 8100 series
switch.
Stacking LED for the Dell PowerConnect 8100/8100F series switch Figure 11.
When the switch is the Master of a stack, the LED glows solid blue. If it is a stack member only, it
glows a solid amber. When in stand-alone mode, the LED is off.
Note: Each stack members’ role (including the Master and Standby) can be defined any time
after the initial stack is created.
Web interface method
Make sure all switches are at the same firmware version prior to configuring the stack, or use the Stack
Firmware Synchronization (boot auto-copy-fw) feature to synchronize all firmware during the stack
setup process to that of the Master. The boot auto-copy-fw command is explained below in this
example.
Select a switch to be Master of the stack and for managing all ports and member units with the stack.
Login to the Web UI for this switch by entering the IP address of the switch into a supported Web
browser. A username and password is required and should be setup beforehand on each switch. See
the switch User Guide for more information regarding username, password, and Web access.
