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 configure 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-configure an Aggregator, so that the configuration 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 Configuration 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
