Stacking 8024/8024F switches using multiple stack links Figure 10.
When a stack consists of three or more members and at least one of those members is an 8024, a
maximum of two (2) stacking ports should be used between stacking peers for several reasons. The
8024 only has four SFP+ ports. It is recommended that all stack members have the same number of
stacking connections and it is recommended the stack use a ring configuration (where the last and first
switches in the stack are also connected). Given these conditions, only two stacking cables (maximum)
should be used between the devices.
Command-Line Interface Method
Be 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 the stack Master and power up this switch only. Performing the command “show
switch stack-ports” will provide two pieces of required information. First, it shows the Unit number for
the switch which is used in the stacking commands. Second, it shows Interfaces of the switch that
may be used for stacking. Since the Master in the example here is an 8024, it will only show four (4)
interfaces, which are the four SFP+ ports.
