• stack-unit unit-number is the stack-unit number.
• stack-group group-number is group of four 10 GbE ports or one 40 GbE port. The valid values
are from 0 to 15.

Examples of Configuring and Viewing Two S5000 Switches in a Stack
Dell Networking OS Behavior: After you configure the 10 GbE ports in a stack group for stacking, you cannot
use the ports for Ethernet data transmission. For example, if you enable stack group 0 for stacking and only
connect ports 0 and 1 to a peer switch, ports 2 and 3 must remain unused for Ethernet data links.
If you do not assign a priority and renumber each stack unit and the stacked switches reboot at approximately
the same time, the switch with the highest MAC address is automatically elected as the master switch. The
switch with the next highest MAC address is elected as standby. As each switch joins the stack, it is assigned
the lowest available stack-unit number from 0 to 11. The default configuration of each stacked switch is
stored in the running configuration of the stack. The stack-unit ID numbers are retained after future stack
reloads.
To verify the stack-unit number assigned to each switch in the stack, use the show system brief
command.
To display complete information on an stack, use the show system command.
The following examples show how to configure two new S5000 switches for stacking using 10 GbE ports.
The second example shows how to verify the stack configuration.
