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 fanout
• show system stack-unit iom-mode
• show system stack-unit stack-group
• stack-unit iom-mode
power-cycle stack-unit
To hard reset any stack unit including master unit.
