Figure 111. Stack-Group Assignments
You can connect the units while they are powered down or up. Stacking ports are bi-directional.
When a unit is added to a stack, the management unit performs a system check on the new unit to ensure the hardware type is
compatible. A similar check is performed on the Dell Networking OS version.
Syslog messages are generated by the management unit:
• the syslog includes the unit number, previous version, and version being downloaded.
• when the firmware synchronization is complete.
NOTE: You must enter the
stack-unit stack-unit stack-group stack-group
command when adding units to a stack
to ensure the units are assigned to the correct groups.
NOTE: Any scripts used to streamline the stacking configuration process must be updated to reflect the Command Mode change
from EXEC to CONFIGURATION to allow the scripts to work correctly.
Enabling Front End Port Stacking
To enable the front ports on a unit for stacking, use the following commands.
NOTE: You can stack a maximum of eight 10G stack ports.
NOTE: After a port is allocated for stacking, you can only use it for stacking. If stack-group 1 is allocated for stacking, you can
use port 49 for stacking but not for Ethernet anymore. If only port 49 is used for stacking, then the ports 50, 51, and 52 are
spare; they can be used for Ethernet.
1 Assign a stack group for each unit.
CONFIGURATION mode
stack-unit id stack-group id
Begin with the first port on the management unit. Next, configure both ports on each subsequent unit. Finally, return to the
management unit and configure the last port.
The range is from 0 to 3.
2 Save the stacking configuration on the ports.
