Renumbering a Stack Unit
To renumber a stack unit to reset the unit numbering for a master, standby or member unit, enter the
stack-unit renumber command in EXEC Privilege mode and reload the switch.
• If you renumber the master switch, you are prompted to reload the entire stack.
• If you renumber the standby switch, only the switch reloads and is replaced by a member switch that is
elected as the new standby.
• If you renumber a member switch, only the member switch reloads.
• If you renumber a switch to a number already assigned to another stack unit, the following error
message is displayed:

Provisioning a Stack Unit
You can logically provision a stack-unit number to accept only an MXL 10/40GbE Switch. Provisioning is
a type of pre-configuration that is stored on the master switch and applied when a stacked unit is assigned
the unit number.
When you provision a unit number for an MXL 10/40GbE Switch:
• The base-module ports on the switch (ports 33 and 37/stack groups 0 and 1) are pre-configured for
40GbE operation.
• The 40GbE ports on FlexIO modules (ports 41 and 45 in slot 0; ports 49 and 53 in slot 1) are
pre-configured for 4x10GbE (quad mode) operation.
To provision a stack unit, use the
stack-unit provision command in Global Configuration mode, save the
provisioning configuration, and reload the stack.
To provision a stack unit, use the following command:
