Stacking Commands
Stacking is supported on an Aggregator only on the 40GbE ports on the base module. Stacking is limited to two Aggregators in the same
chassis in a single stack. Up to three stacks are supported in an M1000e chassis.
Stacking provides a single point of management and NIC teaming for high availability and higher throughput. To congure an Aggregator
stack, you must use the CLI.
The stacking commands are always available and operational, whether or not an Aggregator has a stacking module inserted. You can use
the commands to pre-congure an Aggregator, so that the conguration settings are invoked when the Aggregator is attached to other
Aggregator blades.
For more information about using the Aggregator stacking feature, refer to the Stacking Aggregators chapter in the Dell Networking OS
Conguration Guide for the M I/O Aggregator.
You can use the following commands to manage a stack of Aggregator I/O modules:
• power-cycle stack-unit
• reset stack-unit
• show system stack-ports
• show system stack-unit iom-mode
• show system stack-unit stack-group
